Windows 7: Laptop no longer finds 5Ghz band

Laptop no longer finds 5Ghz band

Greetings,

I'm having issues with my wireless 5Ghz connection, since my laptop will no longer find it.
Well, if I disable the network adapter and enable it back on, the 5G connection will show up for a few seconds and then disappear. However, I cannot connect to it, even if I try during the short time it shows up.

My network adapter is a Killer Wireless-N 1202.

Now, the router is working properly, because my phone does detect the 5Ghz band and can connect to it, with no problems.

I think the issue might have started after I updated my network adapter's drivers. which I did this Sunday at around 2:00AM. However, later on that day when I turned on my laptop, I had no issues with 5G.

I noticed the issue last Tuesday. During Monday last week my Internet provider changed the modem and router. However, I didn't use my laptop that day and only noticed the issue on Tuesday, when my laptop couldn't find any connection and asked me to choose one.

The main router I used to have was a Linksys and now it's a Huawei one (which is both a modem and a wireless router). That being said, I've never connected wirelessly to either of those, but to a Netgear r7000 which I connected to them.

Yesterday, I tried hard resetting the Netgear router, thinking it might have been experiencing some kind of conflict with the new modem/router, but my laptop still could not find 5G yet my phone could.

I used the "netsh wlan show drivers" line on CMD and it did show my network adapter supports 802.11a. So, I don't think it's a driver issue.
Two weeks ago (prior to updating my drivers and getting the new modem/router) my laptop could connect to 5G just fine.

So, I'm entirely lost here. Any ideas what my issue might be and how to fix it?

Thanks in advance.

Have you tried rolling back the driver in the Device Manager?

2.g Ghz band signal stronger than 5Ghz band
Is it odd that, according to InSSIDer, the 2.g Ghz band signal is stronger (-45) than that of the 5Ghz band (-61)? My router is a Netgear WNDR4500. Just wondering. Thanks. Arthur
