Are you getting any crackling on your phone line when the router is connected?
Hey, I'm not sure if this is the right place to post this but oh well, here goes.
Ever since we moved house and changed from Telecom (NZ) to Vodafone (NZ), we have suffered from random disconnects. It varies from about 5-30 times a day, which as you can imagine gets somewhat frustrating. Now, being someone who plays games on a regular basis, getting disconnected through something relatively important is extremely annoying and recently has got me kicked from certain things. I'm relatively good with computers but when it comes to the whole internet thing, I'm useless. Also we phoned Vodafone and they said the issue was the filters at the ethernet jacks or whatever they are called. So we spent some money and bought some new ones. For the first two days it went smooth and now we're disconnecting again. Any help would be very much appreciated.
