Evil Connection, Death to BT Options

[Forever Unknown]

Bah.

My broadband connection keeps dropping out. Sometimes after an hour, sometimes after thirty seconds (and anywhere inbetween).

I have so far:

- Purchased new microfilters;
- Purchased a new modem cable & telephone extension lead (our puppies have a habit of chewing through them) - modem cable claiming to be "superfast".
- Deleted a sh*tload of files and stuff I didn't need.
- Run three virus checks (one saying I had 79 (!), but didn't get rid of them, one saying I had 13 and got rid of the SpyWare stuffy, one saying I had one and getting rid of it)
- Renewed my Norton Anti-Virus/Internet Security stuff at £33
- Re-installed my BT Broadband stuff

That's cost me about £65 and hours and hours of grief. I had this trouble when I first started and I know all BT will do is put me on hold for 45 minutes and then tell me it's all fine, or to plug it into the main connection (and describing it... Which happens to describe every. single. connection. in. our. house.), and saying they'll bring someone out if they have to, but at a hefty fee.

It's pretty much driven me to the point of insanity. Anything else I can do before I bite the bullet and give BT a call?
