Internet sucks!!!

I have been having so much trouble the last few days with my internet....well, my mother's since I don't have service at my own home yet. I could use the internet but not get onto my Yahoo mail, post on blogger blogs, and log onto sites like twitter and a college website.... I have no idea what's wrong. I tried everything, short of calling the network provider. Firewall is off, the sites are not blocked (as far as I can tell), and the internet is connected fine because I can still search on yahoo and read blogs and such. Oh well, I have my own little laptop and brought it over to her house to use the wireless internet.

So sorry about not posting anything in days...I promise to get a few good posts out soon. :)
