DSL problems

I have been having a frustrating month with my ISP and their apparent inability to fix on going DSL problems. The only plus side to all of this is finding a new reply from linux's ping command. My connection is often so bad that a high level of packet corruption occurs. Its nice to know this can be easily seen. Its too bad you don't see this from Microsoft's ping.exe.

Hopefully being shuffled around to 4 different technicians (not counting SLA nazi's and phone support) and finally having some cards replaced on the switch is getting somewhere, but from the lack of communication between the telco and their repair contractors it looks like it is time to try my luck with some 3G broadband. Since the problem only really happens between 8am and 8pm, I'm thinking it is heat and bad equipment related...but i'm just a customer, what would I know? Connection dropped 2 times while writing this.
