Quick question on intraweb and router

[Swi1ch]

I used to have BT Broadband, and it was slow and kept cutting out all the time. I'm now on o2, and whilst usually getting 6mb+ and occasionally 4mb+, it sometimes either drops down to like half a mb or cuts out altogether.

I initially blamed this on the fact it was coming down a BT pipe from the exchange, but after reading up a little (Had the whole Steam connection problem) it seems it might be the router.

So what are the chances that it's actually the router causing cut outs and speed drops? It's a standard o2 wireless box which is apparently speedtouch and has problems.

Um, it's plugged into a DSL filter splitter thingy, then into the phone line connection in the wall. Dunno after that.

think swinnie meant is it plugged into the master phone socket or is it running on an extension.

Extension.
