Someone managed to install something more recent than that? What could have changed from 38253 onward to just brick them?
My new build release notes wrote:
k2.4 (broadcom/) builds were fixed in 39715 (broken in 39144 through 39654)
I don't recall issues shortly prior, but I also wasn't testing my old WRT54's then.

I was able to move from Tomato 1.28 to DD-WRT v3.0-r40189 mini (07/04/19) on my WRT54GL v1.1 like that:
1) 30-30-30 (hard) reset made on Tomato 1.28;
2) Flashed through Tomato 1.28 web interface to DD-WRT 07-04-2019-r40189 (dd-wrt.v24_mini_wrt54g.bin) listed as Beta version successfully;
3) 30-30-30 (hard) reset made on DD-WRT v3.0-r40189 mini (07/04/19).

All went OK and so far it looks stable. I will write here if something is not quote well in the future.

So far found that:
1) "klogd" can NOT be enabled, leading to no possibility to log in a file firewall logs if enabled (the same can be seen from the GUI and with "dmesg" from the CLI).

Upgraded successfully using https://wiki.dd-wrt.com/wiki/index.php/Linksys_WRT54GL from DD-WRT v3.0-r40189 mini (07/04/19) to DD-WRT v3.0-r41664 mini (12/06/19), dd-wrt.v24_mini_wrt54g.bin, on my WRT54GL v1.1. Everything looks good so far.

"klogd" still can NOT be enabled.

Does anyone have any recent-ish reliable firmware for a WRT54GS v1.1?

I am asking because with FreshTomato 2019.2 and 2019.3, while they seem to be okay in terms of general function, it has issues with uptime as the router seems to reset the uptime after being online for not all that long (within a couple of weeks tops and earlier today not even a full 24 hours before apparently resetting the uptime).

basically I just want something secure and can do all of the more basic stuff people use and be able to stay online as long as the router has power to it (so could be several months or years).

EDIT: I got r39715 (from May 2019) installed for now given the info above using "dd-wrt.v24_mini_wrt54gs.bin" ; ill see how this works over the coming weeks as if this is stable for say 1month+ chances are it's good and there is a fault with FreshTomato 2019.2/2019.3 etc.

The GSv1.1 wiki says to use the mini_generic.bin.

If you're having stability issues, and this is an old unit, it is probably failing caps. Search my posts for `cap*`.

Also, you should be using a recent build that fixed the rekey issue (after r41662). E.g. start with 41686.

EDIT (Jan 8th 2020):

I was having a issue with 2019.3 firmware not being able to have a uptime of more than roughly 1 day to maybe as much as a couple of weeks tops and I thought going back to 2019.2 would fix it, as 2019.2 worked fine for me in the past with no 'uptime' issue, but the issue still remained as I could not even get a full 24 hours of 'uptime' on a recent test.

so I figured I would give DD-WRT a shot as I initially flashed from FreshTomato 2019.2 to DD-WRT r39715 (May 3rd 2019) and reset through the interface like usual etc, and that was working with wireless but I figured it's best to run a more recent build etc and then tried r41686 (apparently has fix for 'rekey' security issue etc(?)) and that's when the wireless showed 'Radio is Off' in the DD-WRT interface and resetting through the interface did not seem to do anything so I played around with even a bit more recent builds etc and I figured nothing was working so I said the hell with it and flashed back to r39715(May 3rd 2019) and at this point the wireless was still reading 'Radio is Off' and at this point I knew something had to be out of whack with the configuration stored on the router. so I flashed back to r41686 (Dec 10th 2019) and then after it was up and running I held the routers reset button for 30+ seconds and at this point once I got access to the interface the wireless was now working once again! ; so given that info I am starting to wonder if FreshTomato 2019.3 (and even 2019.2 in my most recent check) will be perfectly okay with no uptime issue if I reset using the reset button instead of doing it through the browser interface.

but what ill probably do for now is see if DD-WRT r41686 (Dec 10th 2019) stays stable for roughly the next month or so and if it's good ill probably go back to FreshTomato 2019.3 and just make sure to use the routers RESET button and hold it for 30+ seconds instead of clearing NVRAM etc through the interface as I think it's plausible that was my issue the entire time with the router having uptime issues.

p.s. I am using "dd-wrt.v24_mini_generic.bin" (or if not that it's "dd-wrt.v24_mini_wrt54gs.bin").

What do you think the chances are that the two capacitors in my ASUS router are bad? ; because that router is pretty much shot as it's not stable (has trouble keeping any decent uptime and wireless seems to sometimes be on and other times it's like it's not even there with wireless light off) but physically looking at those capacitors, no obvious issues like bulging etc. but currently I put it back together, so I can't easily check any info inside of it at the moment.

as for the Linksys WRT54GS v1.1... since I had to go back to this recently because that ASUS router is not flat out not stable ill see how this router is over the next 2-4 weeks or so as I figure if I can get a solid month or so without any issues, it should be stable enough Smile

If the stability is dropping over time on an old router, that's a pretty high probability of failing caps. And as you'd see in all my posts about them, none of the many bad router caps I've repaired ever had a visible sign of it.

Well it was basically acting up initially around June/July 2019 (I want to say it's roughly 10 years old now) and that's when I switched to the Linksys WRT54GS v1.1. but was playing with the ASUS WL-520gU recently and noticed the wireless was flaky as the LED light would not even come on after some hard-resets etc and as I was about to give up, I noticed it came back on etc.

but assuming the caps are going to bad... is it even worth fixing? ; because I suspect it depends on cost as if it can be fixed for next to nothing it might be worth attempting to fix it and, if I bother with that, I wonder if it would be worth swapping the caps on the Linksys WRT54GS v1.1 I got(which I never opened up yet to see what's in there)? (but I am still testing to see how it fairs over the next month or two as I figure if it does not act up by then, it should be stable).

I do have a soldering iron and some flux etc as I did a bit of soldering on original XBox years ago on it's board and for one which had a mod chip I did some soldering on a pin header.

Thanks for the info.

Or if you mean the 520gU, the electrolytics are here:https://forum.dd-wrt.com/phpBB2/files/asus_520gu_inside_179.jpg


Mine looks almost the same but there is NO heatsink on what I assume is the main CPU chip on mine as I just opened it for the first time about a day ago. but did someone add that heatsink in that picture?

even touching it (WL-520gU's main chip) with my finger (I touched the side of my computer case first to help minimize the chance of static electricity getting to ASUS WL-520gU components) it's a bit warm (as I can feel some heat in it vs some of the other chips feel more neutral to the touch) but it's not even slightly close to burning me.

-------------------------------------------

EDIT (Feb 3rd 2020): replacing the capacitors (I found some used ones around the house (16v 470uF 85c (stock caps are 105c rated)) on Jan 31st 2020 seems to have fixed my ASUS WL-520gU router as it's no longer unstable with uptime issues etc. I currently have 3 days 8 hours of uptime which in recent memory it's unlikely it would have made it this far prior to the capacitor replacement as it would usually kick out within a day to maybe a few days or so tops and not long ago the wireless seemed dead as I did hard-reset etc and out-of-the-blue some odd minutes later, when I was about to give up, it came back online as the LED was lit up like normal once again etc. so at this point I am confident replacing the caps fixed it but ill be even more confident if I can get a full week or two.

so given that info... I am pretty sure replacing the caps on my Linksys WTY54GS v1.1 will also fix that which I suspect ill probably get a hold of some Panasonic ones on Ebay eventually which are four '25v 220uF' for my GS v1.1 router.

BCM53xx chips run pretty cool, so a heatsink isn't needed unless in extreme ambients (or clocking over 250, but the Asus' 5354 is locked at 240 anyway).

Should you bother? ...that all depends on you. Wink They are pretty easy to swap. Fwiw, I've got caps that I could sell cheap, and so far have been able to ship w/ just a stamp. PM if interested. Smile

I see in the more recent builds it shows...

"9. CVE-2019-14899 VPN fix (r41784: applicability depends on VPN setup) and GUI toggle (r41812): ticket 6920, 6928, 6931, 6932"

I realize I am not using VPN, so I assume r41686 is still secure for me, but I figure it would be a good idea to use a more recent one for good measure on the chance VPN is used at some point in the future.

so what do you suggest for the recent builds on a Linksys WRT54GS v1.1? ; I mainly just need to make sure the router does not get bricked flashing and that I can change back to another build if something acts up as I know r41686 is okay in this regard since I had no issues changing from DD-WRT to FreshTomato and from FreshTomato back to DD-WRT through the interface and I think I had about 8 days of uptime on r41686 before I was messing with other stuff etc.

is r41813 stable enough for general AP use?

on a side note... I believe you said it was safe to overclock to 250Mhz on a stock WRT54GS v1.1? ; or is 240Mhz a bit safer? ; assuming I can, there is no chance this can brick the router, correct?

p.s. I got capacitors (Panasonic brand) on the way which ill be using to fix the WRT54GS v1.1 router I got.

I've never run a WRT54 at less than 250 (note the 5354 is locked at 240). The original 4000-series SoC spec was at 250 MHz with heatsink, and the 5000-series run much cooler and don't need one regardless.

I just updated mine yesterday actually. Wink If you need IPv6, use nokaid-generic or voip_generic.

Well after about 6 days of uptime on FreshTomato 2020.1 the ASUS WL-520gU acted up and lost it's uptime so I am thinking it might be more of a issue with FreshTomato than the router itself(?), which is why I switched back to DD-WRT to give this a try. but for whatever reason the AIR light (the Wifi light) on the ASUS router will not come on at all, so I have no wireless.

I was trying to reset it etc (using https://wiki.dd-wrt.com/wiki/index.php/Asus_WL-520GU ) but nothing seems to work.

any suggestions?

p.s. I had this issue not all that long ago before I replaced the capacitors and out of no where it seemed to come back on. but currently it's off and it's like wireless does not exist on that router.

@jwh7 ; thanks for the info on the WRT54 series as after I replace the caps (which ill likely be doing sometime early next week) ill switch it to 250Mhz and see what happens.

EDIT: maybe it was a fluke but I flashed back to 14929 build with the .trx file on the WL-520gU and then waited a while and flashed to r41686 and, for whatever reason, the AIR led is back on and everything seems okay. but last time I had this issue, before replacing the capacitors, I never did this and it came back on, which seemed to be out of no where. so it's hard to say if what I did above had any real effect on things. maybe it's a weird glitch changing from FreshTomato back to DD-WRT (or vice versa) occasionally etc(?) because that's the only time I noticed the wireless AIR light completely staying off as it never done that once things were in decent running order on FreshTomato or DD-WRT (even after losing uptime on FreshTomato etc) as it seemed to only do that (at least on the two times it occurred so far) when changing firmware if I recall correctly. but hopefully DD-WRT stays stable so I won't have to upgrade the firmware anytime soon Wink

so now at this point ill just have to sit back and see how DD-WRT r41686 fairs over the next couple of weeks on my ASUS WL-520gU as I figure if it does not act up within a couple of weeks (maybe a month tops), chances are DD-WRT r41686 is stable where as FreshTomato 2020.1 is not.

p.s. but I guess maybe there is still a possibility the replacement capacitors I used on the ASUS WL-520gU, which were used, are faulty, just not as faulty as the ones that were originally in it? ; but I would imagine if DD-WRT is stable and FreshTomato is not, that would get one thinking it's more of a FreshTomato firmware issue and less likely it's a hardware issue. but if DD-WRT also acts up, maybe that opens the possibility the used capacitors I am using on the ASUS router might be a bit so-so, just not as bad as the original ones previously in it. either way, given I am replacing the capacitors on my Linksys WRT54GS v1.1 soon with name brand ones (i.e. Panasonic) then I can be confident those won't be faulty and then I can test FreshTomato and DD-WRT and see what plays out Wink

-------------------------------------------------

EDIT #2: is there any way for the following script to work with static IP's instead of just DHCP connections? ... https://wiki.dd-wrt.com/wiki/index.php/Ad_blocking ; because that seems to work for DHCP connected clients but does not work when I setup a manual IP address given the ping times etc as the one with a static IP will ping something blocked in that MVPS HOSTS file (i.e. the MVPS HOSTS file is not working) but on the DHCP connected devices, stuff listed in that HOSTS file is blocked (i.e. the MVPS HOSTS file is working).

but will that MVPS hosts file be automatically updated once in a while with that general script? ; or does it only do it upon reboot? ; because it would be nice if one could update it about once a week.

EDIT#3: well I noticed a moment ago that it appears even my computer with the static IP is filtered properly with the MVPS HOSTS file now. I would assume it's on a slight delay after boot up before it takes effect(?)

but assuming all of that is fixed, does anyone know if that script there on the site (the first one listed(which just works with MVPS HOSTS file), not the long one that seems to require 32MB of RAM) automatically updates here and there WITHOUT having to reboot the router?

EDIT #4 (Feb 9th 2020): well in relation to my "EDIT #2" I think I figured out how the 'cron' thing works, which does automatically update it, given this website... https://opensource.com/article/17/11/how-use-cron-linux ; at the "Other scheduling tricks" section I can change it to update once a week instead of updating once every day (as I figure updating once a day is too often as once a week is plenty) at 12pm like it does given the way the cron stuff is entered on that ad blocking website in my 'EDIT #2'. so basically...

instead of what's shown...

0 12 * * * root /tmp/.rc_startup

I can change it to something like...

0 12 * * Sat root /tmp/.rc_startup

so instead of updating every day at 12pm it would then only update once a week, on Saturday at 12pm. or to change to 1pm on Saturday, I can do this...

0 13 * * Sat root /tmp/.rc_startup

@jwh7 (or anyone else)...

What voltage do you get from your 12v rated Linksys WRT54GS power supplies?

because mine, which is the official adapter for it, is rated at 12v 1000mA. using a multimeter it measures 16.98v (give or take a little). that seem a bit high to you?

I even have some random generic power supply (see "p.s." section below) that's rated @ 12v 1000mA and that measures 14.19v and this also seems to plug into the Linksys WRT54GS v1.1 router I have and it powers up (but that was about as far as I have went with it so far is a basic power on test). I have not really tested it for stability, which I might once I replace the caps as they should be here soon (should have been here today but got delayed), especially if the official adapter acts up.

one last thing... when plugging in the power to the WRT54GS router and it's on you can hear some noise coming from the router. I assume that's likely from bad caps? ; it's not loud or anything but audible as shortly after you unplug it, the noise is gone.

on a side note... DD-WRT r41686 (Dec 10th 2019) is still working okay so far on my ASUS WL-520gU as it's got 3 days and 8 hours of uptime and so far everything feels good. I am going to try to get at least a full 7 days maybe a bit longer out of it as FreshTomato 2020.1 made it to about 6 days of uptime before resetting. but based on my gut feeling... I suspect DD-WRT r41686 will stay stable and FreshTomato 2020.1 is a bit suspect and given I got a HOSTS file to work on DD-WRT (for some general ad-blocking), I am not as concerned with going back to FreshTomato now.

but I may still test out FreshTomato 2020.1 on the Linksys WRT54GS v1.1 once I replace the caps just to see if it still acts up as if it does not, within say a full 7 days, maybe the used caps in the ASUS are a bit suspect(?), but if not, it's probably a FreshTomato issue I would imagine. but personally I am starting to lean towards DD-WRT being more stable than FreshTomato on these older routers.

p.s. but I got a hold of that generic one at a auction bundled with some crap not all that long ago. but apparently, given what it shows on the side of the sticker, it's made for charging some 'RAZOR Power Core 90' electric scooter apparently and shows a May 21st 2018 date on the sticker.

EDIT (Feb 12th 2020): I installed the quality Panasonic capacitors (low-esr/105c etc) in the Linksys WRT54GS v1.1 on Feb 11th 2020. it currently has DD-WRT r41686 on it (so I might just stick with this and skip FreshTomato for now). but my ASUS router currently has 4 days 13 hours+ of uptime as I figure if I can get another week or so I would imagine the odds are good it's stable in general. then ill shut it down and switch to the Linksys WRT54GS v1.1 since it's the better router anyways (and ill use the ASUS router as a backup to the WRT54GS) and I might as well use it since it's got brand new quality caps in it.

but I noticed as far as overclocking options on the WRT54GS v1.1 it shows 192Mhz/200Mhz/216Mhz(which is default)/228Mhz/240Mhz/252Mhz/264Mhz/280Mhz/300Mhz ; but I simply am not going to try anything over 252Mhz as I don't want to risk a bricked router.

but just playing around with it a moment ago... 252Mhz does not seem stable (wireless dropped connection and router seems to reboot itself once every 5-10min in my brief testing) where as using 240Mhz it does seem stable as I am currently at 20 something minutes of router uptime. since I am still using the ASUS ill probably let the Linksys sit for a day or two and see if it holds it's uptime overclocked at 240Mhz.

I checked CPU info using "cat /proc/cpuinfo" (without the ") and it shows BogoMIPS = 239.20 ; and "dmesg|grep -i hz" (without the ") shows... CPU: BCM4712 rev 1 at 240Mhz.

but since we are on the topic of overclocking... is it safe to upgrade firmware when the router/DD-WRT is in a overclocked state? ; or is it much safer to put the CPU back to it's default speed (which is 216Mhz) before any DD-WRT firmware upgrades/downgrades?

ill probably edit this post if anything new comes up.

Because it's an unregulated supply; 14-17v is common for a 12v unreg. As the load (current) increases, the voltage drops. Naturally, regulated supplies are more expensive to make. Wink Out of all the older Linksys routers I've had, only one (for the GSv6 I think) is regulated. Measure it when you plug it in; it will drop then slowly come up as boot completes.

Most likely it's inductor ringing; that's why they usually have epoxy (or hot glue) on the coils.

That would be difficult since there isn't a build for it (no k2.4). Smile

GSv1.1 defaults to 216? The specs I've seen still show 200 until the GSv2. Granted, the manuf sometimes changes things leading up to model rollover. Is the S/N prefix CGN2, or did you change the CFE? Did you add a heatsink? As I said, the BCM4712 was specs at ~250 with a heatsink. I ran my GSv1 at 264 actually, but 240 is a good default due to the pll tables. Last I knew, DD did not set clkfreq correctly for the v1 (perhaps fixed with v1.1) and the CFE did not failsafe, thus bricking until I fixed it via serial. There's an old tomatousb post I made about it...
Ah ha, ref'd here:
