EX8300 slow videcall wificalls

Installing and Using OpenWrt

Hi Guys,

I just migrated from and archer a7 to a ex8300, and I have the problem that videocalls/wificalls from my iphone are very laggy when connected to my 5gz wifi (rete1)

speedtest and ping I guess it looks good:

While orthogonal to your question, please only use channels 1, 6 or 11 on 2.4 GHz. While the graph might make it appear to fit in quite well, you have partial overlap with both the channels on 1 and 6, which is worse than full overlap using the conventional channel roaster.

With full overlap, your AP both only has to deal with one conflicting network in your vicinity (rather than with two, each at their own pace), but it can also recognize the other BSSID as being network traffic (it's encrypted, so it can't read into it, but it can adapt its strategy to avoid it best), rather than being indistinguishable noise.

The same if obviously also valid on 5 GHz. If you can't avoid other networks completely, always prefer full overlap following the conventional channel roaster over partial overlap (just choose the leat crowded channels, but always 1, 6, 11).

@slh
Thank you for the suggestion.

Regarding my 5Ghz, radio0 the AE8300 (QCA9888), is limited to channel 100 and above.

however if I move the channel below 149 the wifi seems not work, I also see the dark vertical like at 149 here

So what are the equivalent of channel 1,6, 11 on my 5Ghz QCA9888 (limited to 100 and above) and (IPQ4019) limited to channel 64 and below.

THanks
