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:
for 5G:
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:
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
