New desktop doesn't detect my personal wifi network

[PoeGamer]

I have been looking everywhere on the internet for a solution to my problem, but nothing has worked. I just purchased this computer:

http://www.bestbuy.com/site/ibuypower-desktop-amd-fx-series-8gb-memory-1tb-hard-drive/5574049.p?id=1219143550897&skuId=5574049

I set it up yesterday at a friend's house, and I was able to connect to his wifi without a problem. I brought it to my place today and for some reason it doesn't detect my wifi network. It shows a handful of the neighbor networks but not my own. There are currently two other computers that are connected to the same network without a problem. I have reset the router, reset my computer, uninstalled and reinstalled the wifi adapter, verified that the adapter can connect with both 2.4 and 5GHz signals, attempted to manually add the network in case it was hidden, and nothing has worked. At one point it detected the signal, but it had 'limited' connectivity and no internet before disappearing again a minute later. That was about 7 hours ago and it hasn't returned. I don't think interference is a problem as my laptop and phone can pick up the signal easily from the exact same location. My router was provided through my cable company, Brighthouse.

Any thoughts would be much appreciated! Thanks!

if it a usb dongle make sure it has the newest drivers. look to see what chipset it uses and download the newest driver from the chipset vendor. look online see if your wifi router has any firmware updates.

Smorizio, thank you for responding. I'm still a little new to this, so I apologize if I sound ignorant. I decided to move my desktop to the same room as the router to see if it could pick it up there. Once again the network wasn't visible, but I was able to manually enter in the network information and get connected. Optimistic, I moved back to my desk a couple of rooms away, and I'm back to my old problem. If it connected in the same room as the router does this mean it should have up to date drivers? Since the router is owned by my cable company, I don't know how I would check for firmware updates. One last thing, I don't have an antenna to better detect the network. I looked online and it doesn't appear that I have the ports required to connect these antennae. If I get a USB one, will it be able to connect to my adapter, or do I need to get a new adapter to plug an antenna directly into it? I'm hoping that this will solve my problem, but I'm still baffled that I can detect the networks of my neighbors without an antenna.

think what your having is a chipset issue with the router that came with the isp. What I would do is pick up a newer wifi router and plug it into the lan port and set it up as an ap. if your desktop connects fine to it then it a hardware issue with the isp unit. the free fix would be to swap out the older wifi router from the isp with an updated unit. most times all you do is walk into the local office and swap the units.

It took me a while, but I was able to get in contact with my cable provider. I explained the situation to them, and they had to adjust the internet settings. I'm not entirely sure what they did, but the connection immediately showed up and has been stable ever since. They didn't even have to reset the router. Thank you again for all your help. I have a feeling that if they didn't have the ability to adjust it remotely I would have had to do exactly as you recommended, as the technical support member said the adjustment should make the connection better suited for both new and old computers. Thanks again!
