I've split up the 2.4Ghz and 5Ghz networks into two different SSID's, but I am having trouble with the channel assignments.
The Superhub keeps insisting on putting the 2.4Ghz network onto Channel 11, and the 5Ghz network onto Channel 44.
These channels are very congested with 4 other networks also on these channels, according to my Wifi Channel Analyzer app (Virgin is the only choice here for fast broadband with no Openreach options, so I have competition from 4 other neighbours with VMxxxxxx network names on the same channel).
In the router I
- Navigated to Advanced Settings > Wireless > Wireless Signal
- Chosen 'Disable channel optimisation' under the Smart WiFi section
- Selected 'Manual' for the channel and chosen 6 for 2.4Ghz network
- Selected 'Manual' for the channel and chosen '36' for 5Ghz network
- Applied the changes
The wireless drops for a few minutes then comes back up, on 11/44 again, when I revisit the settings page, it's retained most of the options (e.g. its left Smart Wifi disabled and the channels on 'manual') but the actual channel selection dropdown has reverted back to 11 and 44.
I have factory reset the router as well as the usual restarting it. I actually managed to get it to stick on 6 and 36 for about 24 hours, before it reverted itself again overnight and now I'm back on 11/44.
The practical trouble for me with the 5Ghz network on Channel 44 means when my laptop is connected to it, I get about 18Mbps download speed. When I manage to persuade it to get onto Channel 36, I get the full 110Mbps download speed.
I was going to give up and buy an external Netgear wireless router but then I think I shouldn't really have to do that, the router should keep on the channels I want which is enough to give me a brilliant connection.
