Need MAJOR help with router issues
Hello everyone. I have been trying to find an answer all over the internet, but have come up short so far. Hopefully someone here will be able to give me some good advice.
My ISP is Comcast, and a few years ago they gave us a router to use for our cable internet (the model is Netgear CG814WG). Everything has been fine until a few months ago when some of our computers were frequently disconnecting (five or six times a day). According to our laptops/desktops, it said that the PCs are connected to the router, but the router was not able to connect to the internet (also mentioned something about not being able to contact DNS server, I forget).
Even with all these frequent disconnections, we would still get through eventually. But today when I came home from work and booted up my laptop (which is always around 10 or 20 feet away from the router), it would not even connect to the router. This happened also with the other laptop in the house and a desktop that runs with a wireless network adapter.
Now, before I go on any further, let me explain the situation in the house. There is one desktop directly connected to the router via Ethernet cable. There is one desktop 30 feet away that connects with a wireless network adapter. There is one laptop 10 feet away that has its own built in wireless network adapter, and there is another laptop on the other side of the house with the same build. All these computers have worked at various other places (Starbucks, university, etc) without any problems. So I conclude that it is not any the computer's faults.
As of now I am giving all the blame to the router. The two laptops, including the one desktop, are all right now connected directly to the router via Ethernet cables, and they have perfect internet, but the second I try them out with just wireless, they are unable to connect.
1) Buy a new router
2) Call a Comcast rep and ask for one of their workers to come out and help us directly.
I want to avoid the latter because they'll probably give me a big fat service charge.
1) If I buy a new wireless cable router, do I have to buy directly from Comcast or can I go to Bestbuy/Walmart and buy one from there? If so, is it easy to set up?
2) Do you think this is the right way to go? Could there be another reason why my internet experience is failing?
Thank you for reading my novel and hopefully we can get some discussion going.
