Hello, and thank you for using this service.
Sorry you are having trouble. I will help you now.
It sounds like you own your wireless router, and it's connected to a DSL modem. Is that correct?
What is the model of your router? You can find this on a label on the bottom of the unit.
OK. We are not earthlink, and so I wouldn't really be able to tell you exactly what they could provide or if it would be any better. It is also doubtful they would be able to give you an informative accurate answer on that.
However, if you own your router now, it would usually make sense for you to continue to own your device, and upgrade it strategically to suit your needs. I can help you with that, and would recommend that you do so. The ISP equipment is often more costly, and more difficult to maintain over time. You also don't have nearly as many choices as you do when you own your own router.
So, just let me know if you'd like to proceed here, and if so, please send back the model of your current router so I can see what options you'd have for a worthwhile upgrade. thanks.
