Intel 9260 Wireless behaviour

[steve_togo]

I had an intel 8260 wifi card on a gigabyte PCIE card for my desktop. Recently i was having issues where 5 ghz was not visible or not working. I replaced the card with a 9260 and i stgill have the same issue.

The weird thing here is I can see other 5 ghz networks and connect to it if i use a different router (Wifi + Modem) combo.

My primary AP is TP-Link EAP 225 and I cannot see the 5ghz broadcasted by these AP's. The 5 Ghz network from this ap is visible on my phone but not on my PC using intel 9260. I have done the following.

1. Deleted drivers and updated multiple times
2. Created a spearate 5ghz network, changed security settings to include no security.
3. Rebooted multiple times.
4. Reset the AP

Still no luck. I would appreaciate if there is any insight on this issue.

Thanks!

What channel are you using?

Right now I have 2 AP's and they are on channel 161 and 48. Interestingly I can now see and connect to 5ghz network but not to the one from my AP. I checken my WLAN report and I have the following error.

What channel are you using?

Do they have a selective channel that it works against?

I was asking to see if you were using a DFS channel. You are not.

Did the 8260 card ever work with the TPLink AP? If yes, what changed?
What version EAP225 are you using?
What is the make/model of the AP/router that the card connects to?

Yes it was working with 8260 fine before.

My AP is EAP 225 -v3 and ER-X is my router.

Today i was able to connect to the AP only if i roll back the driver to 20.120.1.1 and set my 5ghz property on my AP 80 Mhz only. It does not work if i set it as 20/40/80. Also the connection rate is super low. It is not going more than 173.3 mbps

Which router it this that you say works?

Yes it was working with 8260 fine before.

But you started this thread by saying:

So what happened to make the 8260 have "issues"?

173.3 Mbps link rate indicates 20 MHz bandwidth operation

Have you tried changing any 9260 settings in its Wireless Properties?

Disable MU-MIMO on the AP if you can.

Its working with an SBG 6700 AC

8260 worked fine for more than a year and I replaced the card with a 9260 thinking the issue was card. Anyways I would like to use my 9260 now and I contacted inte, they wanted me to recah out to Dell to see if they had a driver for me. I use an optiplex 7040 and does the system or the processor matter here?

I tried changging a couple of settings on the AP as well as the card.

Forcing 5 ghz
Auto channel selection
etc.,

Please let me know if you would like me to look at something specific.

Thanks!
