AC network detection

[player4]

Hi guys

 

I've got some weird problems with wireless network.

Important-to-know hardware is as follows: ASUS AC-87U router, PCE-AC66 network card, old apple devices, a samsung s8 and a meizu mx4.

 

So, how it goes. The router is about half a year old, just as s8, all other devices match their production date (mac '12, ipad2, several iphones; meizu mx4 is end of 2014 as you most likely have no idea what that is)

Router (all the firmware is up-to-date, tried keeping it off for up to a day) gives off 2.4 GHz and 5GHz signals. 

All apple devices, although lacking the detection range and effective speed, can see and use both networks granted they're close enough.

Meizu MX4 (serves as a transitional testing device in this case) instantly connects to a 5GHz signal, getting strong RX/TX rates (don't really know which is which), this can also be seen by its network speeds.

Now we're getting to the problem.

PC never saw the 5GHz signal since i got the new router. I figured it's the distance (even though MX4 gets strong reception in the same spot, and PCE-AC66 has 3 freaking full-sized antennas), but a week ago i was finally able to connect, also getting a strong signal. 2 days ago, however, i got up, woke up the machine, and saw that the 5GHz signal has disappeared, leaving me with the boring 2.4GHz. Nothing relevant to the situation has been changed in any way (MX4 still sees it perfectly).

Now, the s8 became my main device just a few days ago as it has been used in a different place and i never really needed to check if it was ok with ac signals. And as it turns out, it can't see the 5GHz either, even when its really close to the router! Note that I didn't get the chance to test it in different places with ac yet though.

 

This is where you - the community - comes in. I'm fine with the s8 being on a 2.4GHz  (although it would be nice to have it on a faster network), but I really really want to use the 5GHz on my PC. 

Please help.

 

P.S. I try to keep all the devices off of the 5GHz network to have the least interference when trying to get a signal on a PC.

Sorry if there are any mistakes, my language doesn't even use latin alphabet. 

 

 

Edit: If anyone has the similar problem - it turns out, i shoud've played with the selected channel from the start as it seems not all devices can see all chanels. Sorry for being dumb. Admin, you can delete this post.

It's actually not that dumb, lots of people will overlook wifi channels, all 10 wifi networks around my house, minus mine and 2 others are all on channel 1 (with tons of interference I presume).

 

Good thing you fond out what was wrong on your own!

 

The thread can be left open since others with the same problem might find your thread and solution, and if it can help then it's a good thing IMO!
