When you find the time, please explain what's wrong with channel 13?

So i read your link and made the appropriate changes Cheers for the tips

Good stuff, now try out both the 5Ghz and 2.4Ghz bands. I highly doubt the 2.4 will be worse signal wise than your old netgear device....

Ok will do later today.

What about the Billion BiPAC 8800AXL VDSL2(Fibre)/ADSL2+ Dual Band Wireless AC 1300 Modem Router with 3G/4G LTE failover 4 x Gigabit LAN, 1 x Gigabit WAN and 2 x USB port

Yeah thats the one i put in my reply when the other guy suggested routers i could use instead of the BT Hub 5.

I've also been considering replacing my BT HH5 (A) (on Infinity 1). (My main reason is because of wifi issues: every time the VDSL re-syncs (which it does frequently) it causes home network chaos by dropping all our wifi connections - but that's a story for another post!)

I presume none of the alternative routers would maintain the open BT WiFi hotspot that my BT HH5 has alongside my secured private WiFi? If so, would BT detect that I'd effectively disabled the hotspot and so bar me from using all other BT WiFi & FON hotspots elsewhere?

No. BT customers get free access to BT Wifi, no conditions.

OK thanks, BatBoy.

From the BT WiFi section of My BT:

When you opt your home hub out of BT Wi-fi, we will automatically disable your access to use BT Wi-fi across our millions of hotspots in the UK and abroad.

So if you opt out you also lose access to the hotspots. However, if you just use your own router and do not tell BT that you are opting put then the hotspot access is not affected. I know this because I had no problem accessing the hotspots prior to having my FTTP Infinity 2 deployed. However, since deployment I have seen no reason to replace the HH5.
