How to set optimal wireless channel on Aztech FG7003GRV(AC) (or any Broadcom based wifi router) with ssh terminal in order to increase wifi speed.

Being fed up with bad wifi speed of Aztech FG7003GRV(AC) and Singtel unable to help, I bought Asus RT-AC66U as primary router and set Aztech FG7003GRV(AC) as additional wifi access point (by put 7003 in bridge mode). But notices that wifi speed is not that good. Cross checking wifi on Asus RT-AC66U I found that automatic channel selection doesn’t work great. Basically automatic wifi channel selection only saves from huge interference case, but it doesn’t choose the best channel (BTW the same on ASUS). Choosing proper wifi channel manually let increase wifi speed for free. The only problem is that Aztech FG7003GRV(AC) has no user interface at all to see what wifi channels are received at AP. So below the instruction how to do it with ssh terminal. The command should also work on other Broadcom based wifi router, I checked that it works on Asus RT-AC66U.

1. Enable SSH on Aztech FG7003GRV(AC)

http://192.168.1.254/singtel
user: admin
password: H3ll0t3ch

Acccess Control -> Services

SSH - check Enable

Save/Apply

2. Login ssh (use PuTTY on Windows, Terminal on Mac) to 192.168.1.254 the same user and password

2.1 Scan wireless networks

for 2.4G:

Code:
wl -i wl0 scan && sleep 10 && wl -i wl0 scanresults


for 5G:

Code:
wl -i wl1 scan && sleep 10 && wl -i wl1 scanresults

Basically wl0 and wl1 is the name of the wifi interface and it could be different on different modems, but except interface name the same command works on Asus as well ("wl" command is for all Broadcom wifi chips).


3. Look at results and find channel that not used at all.
Set the channel at http://192.168.1.254 Quick Setup -> Wireless and choose Channnel.

I’ve got about 20% speed increase. Your milage may vary.

4. Bonus. To see all your connected wifi clients with their signal level

for 5G:

Code:
for a in $(wl -i wl1 assoclist | sed 's/assoclist//');do echo "$(wl -i wl1 sta_info $a)\n\tRSSI=$(wl -i wl1 rssi $a);";done;echo

See wiki for RSSI - Received signal strength indication - Wikipedia, the free encyclopedia - it is a very good indication of wifi signal strength and so speed.

P.S. I’m a geek. I got ill and had nothing to do.

Best Regards,
Vlad

Good work there... Hope you don't fall sick too often though...

Alternatively, if you have an android phone, install the Wifi Analyzer. It will tell you all the wifi signals/channels... I used this for my home wifi site survey, configuring my wifi on the least congested channels..tuning the power so that i can have more optimal roaming between my APs

Most routers have auto channel nowadays, kind of hard to get a good fixed channel with minimum interference.

I use WiFi analyzer, and inSSIDer on Windows. It's a pretty good software
