My thoughts exactly after reading this thread, the router is broadcasting on too higher frequencies.
This is what I think happens when a new Vodafone Broadband customer gets their new Vodafone router. They plug it all in after activation and then the first thing the router does is a firmware update.
And what happens always is that the THG3000 router always broadcasts on too higher frequencies for both 2.4Ghz and 5Ghz. So 2.4Ghz will select channels 12 and 13 which lots of devices can't pickup and 5Ghz will broadcast anything higher than channel 48.
I have had this happen to me several times after a firmware update on my THG3000 router. This is why I found the solution by using an old version of the Vodafone Broadband app to manually change the frequencies again.
Whoever writes the updated firmware code for any of the Vodafone routers, they could easily solve these problems by fixing this bug in a firmware update. Plus they could also reimplement on both the router and the Vodafone Broadband app to allow the user to change the frequencies again manually. Because it is causing a headache for not only users and this is also one way Vodafone are probably losing customers.
The fact that when people ring Vodafone Customer Services, when you get through to an Indian call centre they are just reading from a script and have no knowledge on solving these sort of problems. Which will be very frustrating to new customers with little knowledge of how to configure a router. Hence then people come to this forum.
Maybe a moderator on here could put this information higher up the chain to resolve these problems.
