SH3 & 9.1.116.608

My router firmware changed to the 9.1.116.608 version last week.

Great improvement on menu changes and 2.4 Ghz wifi n channel width to 40Mhz giving 100Mbps wifi.

Today without any warning it's back to a menu that doesn't change any of the settings and a channel width of 20Mhz with 50Mbps speed.

The channel is fixed on 1.

Does anyone have any idea what has happened, no changes to the settings were made by me.

Nothing I do now has any effect anyway!

I seldom use the 5Ghz band.

I have re-booted the router, that makes no difference.

Any advice is welcomed. TIA!

Maybe VM put a override in the channel width if your in a build up area with lots of wireless about?

Re: SH3 & 9.1.116.608

5Ghz is much better for high speeds. 2.4GHz is heavily congested and 40Mhz is rarely possible on that band. A good router will reduce back to 20Mhz to avoid causing problems for other WiFi users nearby.

There are a limited number of channels on 40Mhz take out far too many of them. As stated, it’s much better, if possible, to use the 5Ghz band.

Re: SH3 & 9.1.116.608

I think the problem I have with non responding menus is/was linked in some way with the smart wifi option being enabled.
It probably saw a congestion problem and switched to 20Mhz channel width.

The firmware stills seems to be buggy though, with the smart wifi option off the menu doesn't seem to connect with the electronics very well.

Back to modem mode with my own router seems to be the only way to get to exploit the potential of +100Mbps wifi at 2.4Ghz.

Thanks for comments though, my next laptop will need to have 5Ghz built in.
I have tried a 5Ghz adapter but it doesn't perform as well as expected and suffers from variable speeds.

Perhaps a future firmware release will work better.

VM must have been out of their minds when they introduced the so-called “Smart WiFi” to the Hub 3.

Have they learned nothing from the MacBook debacle when aggressive signal search strategy of this type caused havoc to millions of users?

>It probably saw a congestion problem and switched to 20Mhz channel width.

I suspect you are correct here which is why the menu entry is "20/40MHz", i.e. you can't force it to 40MHz. I read somewhere that the "rules" are that if there are other devices using adjacent channels - which using 40Mhz (two channels) would overlap with - then it should drop back to 20MHz.

So a laptop with 2 antenna/radios (MIMO 2:2 - 2 special streams) will be able to get ~50Mbps download when close to router on 20MHz - with a connection speed of around 144Mbps. However, most mobiles, cheaper tablets and Android TX boxes only have one radio & antenna (MIMO 1:1 - 1 special stream) so get about 30MBps on a good day.
