Low WIFI speed

[Zero_G]

@Borromini

Forcing 40 MHz on 2,4 GHz is antisocial and a bad idea altogether (you'll only create more interference and your network stability won't necessarily improve, much to the contrary).

No, I'm not forcing 40 Mhz currently, I said I tried with that option on to see if anything changed.

Reset the openwrt to its default settings and follow these instructions:

• Enable software flow offloading on LuCi, on the Firewall configurations.
• Install the irqbalance package and enable it on its configuration file . Reboot afterwards.
• Configure the Country Code option of all the 3 radios to the one of your country.
• Check the 5 GHz bands, on both radios, for empty channels, on LuCi: Status -> Channel Analysis
• Set both 5 GHz radios to the most empty channels on each one, with 80 MHz channel bandwidth setting.

Repeat the tests.

Ok, the software offloading I was already doing it on suggestion of the first post. Irqbalance I already had it installed, but didn't know that I needed to activate it, after activating it, speed went to 290mbps so I would say that is more that acceptable.

But I was searching for more info on the forums and it seems the speed problem on radios started on v20-21 where DSA stopped using multi cpu. (More info here). Supposedly fixing that is a work in progress.
