Asus PCI WiFi Card and Router don't connect at 5ghz

[GregP74]

I recently picked up an Asus model RT-AC1900P router and an Asus PCE-AC68 PCI Express card. The router's running the latest 3.0.0._380_3831 firmware. Card is using the 7.35.315.0 driver for 64bit Windows 10.

The router has been great. It hooks up just fine both with wired and wirelss connections to our smart tv, Roku box, 3 iPhones, iPad, and laptops both on 2.4ghz and 5ghz bands.

The only device I'm having issues with is the one I least expected -- the Asus PCI card in the desktop computer 40 feet away.

On that machine, 2.4ghz connections work every time, solid as can be. 5ghz not so much. Both networks show strength as just fine. Sometimes the 5ghz network will connect with no problems as soon as the computer boots. Other times it sits there with a * on the network connection icon but looks like it hasn't attempted to connect, even though the "connect automatically" item is checked. Other times it tries to connect but I get a message about "Secured, No Internet" or "Checking network requirements" and it tells me unable to connect with this network.

This is turning out to be a real head scratcher for me as everything else works fine. I don't see any rhyme no reason to when it happens. No appliances being used, no neighborhood WiFi networks seem to be conflicting.

what happens if you move around the antenna also for the driver did you use the right one there is one for eu and another for non eu parts .

Antenna doesn't seem to affect anything. I've tried them in different positions on the back of the PC as well as with the extension cord and base.

Driver is the 2nd latest, for non-EU

could you try this card in a another system .

Unfortunately this is my only desktop PC.

 

[scout_03]

you need to find a friend that could test this card for you .

Good thinking.

the other thing you could try is to get closer to the router and see when signal start to fail could be something that intefer with the 5 ghz signal .

That's the thing that's been making me crazy it's not that far and it looks like the signal strength is way up there. Showing as very strong.

 

[GregP74]

I suppose I could also just keep it on the 2.4ghz band. As long as I'm getting 100mbp/s through the wifi I'm not losing anything on my internet.

 

[scout_03]

then there could be a stone wall or another device that use the 5 ghz band that interfer with it , how far from the current place to stong siganl you have to go in distance .

 

[GregP74]

Like I said this desktop isn't all that far from the router. There's a drywall wall but that's about it. Windows shows it as having 5 bars of signal strength. Perhaps something else is interfering at times.

And the frustrating thing is it's random. It connects to the router just fine sometimes then other times it's a no go.

 

[scout_03]

what happens if you use another channel like channel 9 on the router to transmit sim=nce most router run on default as channel 6 and 11 .

 

[GregP74]

I'll have to play around with that. I'm not really as familiar with the 5ghz channels as I am the lower frequency ones.

 

[scout_03]

the channel setting is in the router you change it from the one you have to channel 9 and press apply you dont have to play with card .

 

[GregP74]

Oh yeah I knew that. I'll have to play around with the router settings when I get home nad look at it.
