5GHZ problem

[theinno3]

So im having lots of issues now with my new pc and its PCIE wireless card (REALTEK 8812AE 802.11ac)

In the first hour i got the pc i could connect fine to 5ghz had nice download speed of 150 mbs, now its strugling to connect to 5ghz and if i manage to connect it only gets 10-20 mbs download, upload still seem fine at 20-30 mbs.

On my phone the 5ghz connection is still working fine, on my macbook air i get download speeds up to 300mbs, old school laptop 150mbs. But on this i only manage to connect to 2.4ghz but its maxed out on 50mbs or 5ghz connection with 20mbs, i tried installing different drivers makes 0 difference, and i didint do any windows updates or anything else before the problem occured.

How far away is the computer from your router?

 

How many walls (and of what type - eg: drywall, brick, concrete, etc) are in between?

 

How many other 5 GHz networks are visible nearby?

maybe this will work for you also. ok this again is similar to the issue my son had it took running SG TCP Optimizer.....that fixed his internet. yes i know it doesnt say for win 10 but it worked

seeing this im wondering if some windows update is causing this. if this works you'll be the second one in networking forum that is affected

Computer is right under the router there is a tree wall and drywall its really thin can hear everything thats happening above, only on 5ghz network and 1 2.4ghz, no others in the area i live. 

Like i said phone, macbook, shitty school laptop all work from the same spot. I also have full bars.

Have you tried the obvious, moving the cables and antennas around to try and minimise them getting in the way of each other?  If it just has the small antennas on the back of the motherboard, it can be tricky to avoid the wires and case itself from blocking the signal.

Move the PC around the room a little (it doesn't have to be a lot, a few feet, change the direction the case is facing, etc), see if it changes.

It can even be something silly like somebody has moved something upstairs, or someone sat near the router during the period it was working well, deflecting the signal.

Ive tried moving the anthenas and the pc a little, but i dont see the problem with that since its full bars on the network and since it always works flawless on other devices might just buy new wifi adapter and see if that helps

The other devices aren't sat behind your PC though are they.  Also the "bars" and even "link rate" on WiFi can be completely meaningless, as it doesn't tell you if you are getting a ton of errors due to signal reflections.

i can lift my pc up a little set my phone under the pc and still get the same internet connection, really the router is like max 2 meters over me
