TP-Link C7 v2 2,4GHz intermittent performance, unrealiable

floriangee · January 8, 2019, 10:30pm

Hi guys,

I'm running 18.06.1 on a TP-Link Archer C7 v2. Its a very basic configuration where I use an identical SSID on 5 and 2,4GHz and it's basically just an AP. Everything else is handled by a potent Sophos Firewall.

My problem is, that every few days the 2,4GHz radio locks up. I only notice it when devices which only talk 2,4GHz all of a sudden aren't connected via WiFi anymore. All other devices just switch to 5GHz. A reboot fixes this until the 2,4 band locks up again.

Any ideas what could be done to remedy that?

Thanks in advance

Posting logs of "before, during, and after" would be helpful.

For many, including my five Archer C7 v2 units, they are very reliable and good wireless performers if not pushed hard for CPU or memory.

Good hint, I just saved a system log "before". I'll try to catch logs "during" and "after".

Ok, caught it. The 2,4 band (wlan1) stopped working today at 17:22:21h, here is the excerpt from the log:

After that part, no "wlan1" activity is recorded and the band had 0 associations. A reboot fixed it.

Changing to a less congested channel (likely with less hidden stations) worked for me.

floriangee · January 10, 2019, 9:15pm

I live in a pretty rural area so that's not an issue at all.

robvh · February 24, 2019, 4:54pm

I have the exact same problem, 2.4 GHz locks up while 5 GHz keeps working. I moved my 2.4 GHz channel away from conflicts. I have 2 Archer C7 v2 covering my home, at channel 6 and 12. Here is a log of the radio winding down:

Changing the channel to 6 worked for me to increase the intervals with 2,4gig locking up, but it did not resolve the issue. I bought an AirPort Extreme last gen and enjoy hassle-free WiFi since then.

Hi,

I have the same problem with my TP-Link C7 2.4GHz Wifi dropping from time to time (sometimes twice in a day). I'm running LEDE Reboot (17.01.4, r3560-79f57e422d) and I was hoping upgrading to the latest firmware would fix; but it appears others running on 18.06.1 are facing the same problem.

Any chance this will be addressed ?

Regards,
