Windows 7 Professional Service Pack 1
Laptop Wifi used to recognize & communicate with 5G net, now it can't
I have an HP Pavillion dv6 running Windows 7 professional with an Qualcomm Atheros AR9485 802.11b/g/n WiFi Adapter. My router is a Netgear90. I have a record of 5G communications in my history of network communications. Now my computer can not recognize 5G networks. I have recently moved. Previously I was on a Dish satellite network. Now my network is a century Link DSL network. The router is the same. Any suggestions on what might have happened and how to correct the problem?
At the same time while I had it opened up (and my Asus laptop has to come completely apart) I maxed out the RAM to 16 GB and replaced one of the two 1TB hard drives with a 500 GB SSD.
Even though the network adapter might be extremely easy to replace on your laptop (on most it is behind a removable cover on the underside), some laptop manufacturer's have whitelists in the bios and only those specific network adapters on the whitelist in the bios will be recognized and work.
