Apart from the usual problem of having to repeatedly restart the superhub 2 because the wifi drops out we now have a new problem that has started since an engineer was here yesterday. Until yesterday we were able to watch amazon prime via a smart tv without problems. An engineer was here yesterday to replace one of our v6 boxes which was faulty and also corrected signal strength issues for all the boxes and the modem. Since then we have problems with Internet. When trying to watch amazon prime it now comes up with an error saying insufficient bandwidth. The problem is obviously not with the TV as we had to watch amazon for 5 days without problems while waiting to get our v6 box replaced.
Assuming for the moment that everything you have mentioned is connected by WiFi, then even a few centimetres of movement of the SH2 could change the signal characteristics. I wouldn't dream of connecting a TV via wireless unless it was in line of sight to the router.
Moving on to a different assumption, it could be that the technician has messed things up. The V6 is connected to VM via a coaxial cable ands requires the circuit to be in good nick for programmes to be shown on TV.
So, can we please see your modem stats via 192.168.0.1 --> ROUTER STATUS --> upstream and downstream power levels. That would provide an indication as to whether or not the technician dod the right thing.
Indeed it needs resolving but it's annoying the fact that apart from the video output of one of the v6 boxes packing in totally on Monday, everything else was working as it should without problems. We had to wait till Friday afternoon for an engineer and other than the v6 being replaced things are now worse than prior to his visit.
Well it just gets better. Someone from the it department accessed the router and changed a setting in wifi and said that should sort it and phone back in 2 days if it's not better. The problem is with ANY INTERNET both wifi AND LAN. So I now have poor Internet, the laptop now connects to the router but has no Internet access, the TV can't access amazon prime or Netflix and I have to wait 2 days before I can phone them back. I have had enough of them not listening to what I tell them, they can come and take everything out and I will go to Sky. At least then if there are problems I know what to do to sort it as I was an engineer for them.
... and what's even worse, those people up top at VM know what a shower their offshore broadband support agents are and by not doing anything about it, stick two fingers up at their customers. Disgraceful.
