We could do with seeing your upstream/downstream modem stats plus an opinion from you as to whether upstream power is stable (refresh the screen a few times).

Other than that, you could consider phoning Retentions and demanding a SH2ac or else you're thinking of leaving. You would point out that 152 meg users should have the SH2ac because it is not possible with WiFi on the SH1 to achieve full speeds nor to properly share bandwidth among users. You should make that a demand because VM are cannot in your case match the advertised features, yet you're paying for them. And don't accept to pay £20 for the SH2ac.

The above said, I realise that you are in modem mode and that the SH1 is adequate for that. But if it is defective you don't want them to send you a refurb SH1, do you? And you don't have to mention modem mode on the call.

But first your modem stats so we can take a look.
