As msoengineer stated, coming from a pooched firmware, a reset is highly recommended.

But do as you like.

To backup my settings I use the "print" function in Chrome browser which captures the whole page, not just what you see without scrolling,
in pdf format you can copy and paste from (crc?).

I don't know if other browsers have this feature.

Be sure to expand all text boxes and open any pop-up windows,
such as your summary pop-up at access restrictions page.

Also commands boxes if you have many at .../Diagnostics.asp.

Sometimes line endings are not honored correctly when you paste such as CA Cert box on VPN page, must watch for that.

Hostname box on Dynamic Domain Name System page will not expand to see all but autofill takes care of that as well as many other boxes.
I also keep that backed up to a text document.

Mac addys on wds pages are retained, just need to re-enable and rename. autofill works here.

All takes me about ten minutes to re-config, have done it many times lately.

I am new to the R7800 Smile
An interesting router, lots of new things for me, core affinity, latency spikes etc.

Gotten curious, and set a continuous ping to 8.8.8.8, 1 in 28 packets seems to spike from around 14 to around 70 ms.

I know I am lazy and could start reading the whole 178 pages but is this the latency problem you are all referring to?

I am testing build 40527 which is using K4.9 and did an nvram erase && reboot

use kong builds not brainslayer's, his builds are broken for years with ipq806x latency/load since kernel 4.x, kong fixed this.

Code:
1000 packets transmitted, 1000 received, 0% packet loss, time 9761ms
rtt min/avg/max/mdev = 6.736/9.478/23.097/2.215 ms, pipe 3, ipg/ewma 9.771/8.760 ms

Looks good on <Kong>. If you go from BS to <Kong> do an nvram reset and don't use your nvrambak.bin to set the options back.


I do wonder when we will see the <Kong> update with Cake. (IF it works that is.)

Just a quick guess off the top of my head: In 1-6 commits from now, at the very earliest. Because it's always a 0 or 5, and if he landed on 5, the build would be incomplete unless he merged commits manually. 40549 is the current revision in the repository, and 40545 would be missing semi-vital commits.

Looking at my <Kong> backup folder.
Code:
37900
37940
37985
38100
38500
38570
38750
38835
39000
39705
39830
40270
37910
37945
38065
38340
38535
38700
38830
38840
39345
39715
39855
You are absolutely correct. We are on 40555 currently on the SVN.

Did he commit like 6 things in the past 30 minutes?

Well, now, I'll be damned. Sure looks like BrainSlayer is gettin' busy. I was being a little bit of a smartass, but hell, would you look at that.

Thanks bushant for your advice.
Just before your advice, used to save the whole html page, but the idea of pdf is fine. Smile
I tested both chrome and Firefox with pdf print under Ubuntu, and noticed that with LONG password (60 chars in WPA pwd)
-in chrome the pdf produced shows only the VISIBLE characters in the text-field
-if firefox, the pdf produced shows (when double clicked) MORE characters in the text-field (password), BUT not ALL

Chrome produced pdf are indeed more accurate and better formatted.

Thanks for sharing your tip.

Giuliano

I didn't know you could even use 60 char passwords.

There is nobody close enough here to worry much about wifi password length.

I use KeePass for username/passwords and much more anyway (and love it). I only know a couple passwords.

bushant,
Don't forget the KeePass PW ....might not hurt to let another body very close to you to know what it is.
I have hundreds of passwords for various things all in KeePass protected with key & password.
After my accident 1.5 year ago it twas 'bout 1 month after leaving the hospital before
I could remember the PW to get into KeePass.
twas sad for a while because I was only one that knew what PW was and
EVERYTHING here has been done online for years.

Yep, wrecked to MX bike badly years ago, couldn't remember much for some time.
Never have remembered THAT crash. Still hurts.

Before I sold my business Keepass was better than gold.
I keep it backed up many places and several had to know the way in.

Good advice to remember, Thank You.

'Random' wi-fi password on FreshTomato, is one long sonofabitch, but ain't nobody cracking into the wi-fi when you use 'em. I think these days the minimum 'strong' length is 14 characters, or did they change that recently while I wasn't paying attention Shocked Rolling Eyes I'm thinking I should probably start using a PM soon, just in case I really start getting bad at remembering passwords... /random /off-topic

I sync KeePass between my desktop and phone. My wife has a thumbprint stored on my phone so if anything ever happens to me, she can access my KP database through my phone.

I was looking into core affinity, as I have seen the following advised:
Quote:
Set WAN to second core:
echo 2 > /proc/irq/255/smp_affinity


Below are my interrupts, strangely eth0 can now be found in the "100" directory and its core affinity is set to 2 already

Can I assume that everything is already taken care of and that setting core affinity is no longer necessary?

I am running Kongs 40270
