Had problem with varying speeds going from 8 meg down to 49 k a few weeks ago.

Download cap was 15323 kbps which tier 3 dropped down to just under 14000kbps, gave me a stable connection of up to 8 meg.

A couple of days ago, I found my speeds were varying again, and last night had dropped down to 100k. Reset (switched off) the router and was instantly back up to 5+ meg. Checked the download cap, and it was back up to 15323 kbps.

Got on to Sky this morning, he didn't know why the cap had gone back up 2 15323 kbps, but someone from tier 3 will get back to me in the next 48 hours.

I have my doubts about being contacted, but hey.

Anyone know why this is happening and why resetting the router seems to cure it?
