Thanks Steve I'll go shopping. I'm having weird probs at moment. My router is switched off overnight and about six weeks ago it started taking a long time to get sync when I switched it on in the morning. Thinking it was a sign the modem was failing I swapped to the backup 2-wire.
That's been fine for the last 4 weeks or so, but it's started to exhibit exactly the same symptoms. Eventually it will get synced but it can take up to a couple of hours.
Contacted support and James ran a full set of diagnostics with the modem in the test socket and everything else disconnected. Apparently the line is fine. I can't say I'm entirely convinced since I have recently noticed low syncs recently and the 2-wire reporting a 28dB SNR; the SNR seldom, if ever, now drops below 15dB.
It seems odd that two modems should exhibit the same set of symptoms in such a short space of time but I suppose it's not impossible, hence my looking for another modem.
I had thought of using a cheap single port modem together with a separate firewall. From a wiring pov this would be simple. Not only that but it would become impossible to monitor the signal as the modem would need to be in bridge mode. The 2-wire would have been ideal to use as a simple modem passing PPoE to the firewall, which would have given me a nice VPN setup, but it's gone belly up before I could try it.
