RESOLVED: Network slowdown with 1.10.0

[lucianor]

TP-Link TL-WDR4300 v1, running version 1.10.0 with extroot.
Upgraded using factory image w/o preserving settings.
Same router was running on 1.9.1 before.

On more than two occasions the router stopped responding: I tried browsing the router config page but it timed out. On some occasions it just hanged for a couple of seconds: ssh was frozen for example.

I tracked it down the problem to be with the signal strength: the slowdown were only happening when I was far from the router. I have not measured the power on the place I was - only had an iPad and the signal strength was 2 out of 3 - but where I was I never had any kinda of these problems.

What I noticed is that the 1.10.0 defaulted to channel 11 with a max transmit power of 19 dBm. When I changed to channel 3, the max transmit power went up to 22 dBm, and the connection was much better.

After the channel change, I measured the signal strength on a Gargoyle 1.10.1 client bridge (TL-MR3420) and it was around 67%. Before it was around 75%. I will run some signal strength tests later today with different channels, but my question is:

Does the channel assignment impacts the max transmit power?
Does 1.10 handles the channel/signal/transmit power differently from 1.9?

Yes, by law different channels have different permitted transmission powers.

No these were handled the same in 1.9.x

[lucianor]

Which channel will get me the highest transmit power option?

[Lantis]

What country are you in?
The UI should tell you when you change between channels in the drop down box. Pay close attention to the max transmission power listed.

I'm in Brazil, but using UTC timezone.

[Lantis]

From what I’m reading, 20dBm is the limit across all Channels in BR

Thanks. I've tried multiple combinations and getting coverage at the same level as the previous firmware.

Note to self: take note of all configs before upgrading.
