Hi DDWRT team.
First and most important - Thanks a lot for all the hard work on the DDWRT firmware!
Now to the part which I am unable to find a solution for.
My setup -
WAN router - TP-Link TL-WDR4300 - Functions as WAN gateway without any issues. (r47692)
Second router - TP-Link TL-WDR3500 - Running on r47692. This router is configured in Client mode, as I want to keep the WAN and second networks separate, plus the second router is used only to service 2.4Ghz devices.
Problem - Second router is configured as a 'Client' on the 5 Ghz interface. The 2.4 Ghz interface is configured as the AP. All the devices are able to connect and hop on the internet without any issues in this mode.
The router freezes and all devices lose WiFi on 2.4 Ghz when a big download or upload starts, typically larger than 1 GB. This can be Google Photos upload or a Linux ISO download larger than 1 GB. Even the WAN router stops seeing second router as a client when it freezes.
If there is no upload/download which is big, the second router is rock solid and there are no issues whatsoever.
I have tried different revisions randomly going back last 6 months and this issue surfaces on all the revisions I have tried.
Large uploads/downloads do not affect the WAN router.
I suspect this might have to do with the 'Client' mode I am using, but I am unable to figure out what might be causing this.
CPU usage is consistently less than 20% and I have not seen free memory to drop below 50 MiB. Max IP connections is set to 4096 (default) and average connections I see across devices is around 400.
What am I missing? I do see some kernel errors in the attached log file, line 134, 135, 146 and 147.
Thanks in advance for any insights on this peculiar problem.
It's exactly the same problem on TL-WDR3600 v 1.5. I have 5GHz WIFI and 2.4 GHz is set to totally disable. When WIFI connected devices is switched on and start to download rather big parts of data router suddenly start fast reboot and crash wifi connections. I don't know where is problem. I'm describe problem here: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=331512 beginly I think that problem is solve. Actually problem is still. I'm observe device and it not depend of advanced settings. I'm use tutorials from forum and from dd-wrt wiki. It not solve problem. It not depend of kind of workstation. I try to connect android devices, laptops and problem is still. For example I'm start to download system updates, internet connection go to high speed and suddenly router make fast reboot, after ~10 secs start to work again and this situation is another time. In my opinion device have a problem with stable working. I'm touch device isn't hot and CPU utilisation is ~15 - 20 % and here is OK. In other topic is syslog exist. I'm not beginner user and I don't know where is problem. I'm stay on the newest dd-wrt build and I'm wait for some fixes.
I thought that this might be a bug as the router hangs while processing large uploads/downloads and thought that this is the base functionality and there is nothing special about it. I did try tweaking different settings and combinations but was unfortunately not able to find a working set of settings to fix my problem.
But I understand that this is old piece of hardware and developers probably should focus on more cutting edge hardware and support.
No. Creating a ticket about a lower-end device that you're expecting higher-end hardware performance out of is moot. DD-WRT doesn't turn a Pinto into a Ferrari 308 GTS. And it's likely more a client or configuration issue than anything else...
I personally tried changing Wi-Fi settings, I tried following configuration guides. I'm sure others have tried it too. I genuinely believed that it's just misconfigured router, but now after seeing more and more people with the same exact issue on WDR3500 and 3600, the only remaining explanation that makes sense is a bug in DD-WRT.
Being told that older routers are not a development priority is absolutely fine, however hearing that it's a misconfiguration every single time this issue is brought up seems like dismissing an actual fault. Even in the quote above - can you only expect working Wi-Fi on DD-WRT with a high-end router nowadays?

The TL-WR1043ND devices are close in hardware and I don't see these issues on the v2 that is an AP - I also have one that is configured as a wireless client. I've even downloaded a DVD image over wifi through an anemic TL-WA901NDv2 and didn't see this. But I will say that "following the guides" incorrectly will result in hangs in web surfing alone on some devices. I couldn't even cruise social media on my phone nor could I surf the web on my tablet. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Thanks for your reply. Can you share your settings, maybe? At this point I have nothing to lose, so I would like to try mimicking your settings, as I have racked my brains on this issue for quite some time now. I have literally tried dozens of settings, if not hundreds, after scouring the forums and the internet, to no avail.
