PC Keeps Disconnecting From Network

Hello everyone,
I keep having issues with my PC's network connectivity. Last week our household installed a new router and ever since I am having connectivity issues. My PC constantly disconnects from the network. I have told my PC to forget the network and then logged back in. I have reinstalled my wifi card drivers several times. Not sure what else to do. I know it is not the router that is the issue. My laptop and cellphone have no connectivity issues even in the same room and on the same desk as my PC.

Any suggestions? Maybe just purchase a newer and better wifi card?

Windows 10 Pro version 1909

Ryzen 5 2600
Gigabyte B450 full ATX motherboard
16gb DDR4-3000
XFX RX570
TP-Link TL-WN881ND PCIe x1 802.11a/b/g/n Wi-Fi Adapter

What is the make and model number of the router? Is it dual band? If so, which band are you connecting to, 2.4Ghz or 5Ghz?

It is dual-band. However, there is no 5ghz option to connect to. Two networks pop up the only difference being the name. One just has a 2 at the end. For example, there is "WiFi" and "WiFi 2." When I go to the properties of the networks in windows both show as 2.4ghz. However, like I said before, the router is both 2.4ghz and 5ghz capable. The router is made by BEC technologies.

Open a cmd prompt type

ipconfig /all

post results also check the signal strenght by downloading a eifi checker from MS store and check to see if your router is on the same channel as another close to you

Sounds like power management.

1. Open Device Manager.
2. Find your Wi-Fi Adapter under Network Adapters and right-click on it.
3. Choose Properties then see if there's a Power Management tab.
4. If so, select the tab and remove any tick in the Allow the computer to turn off this device to save power checkbox.
5. OK any change and close the dialog; close Device Manager.

Hope this helps...

If you look at the setting for the router, do those names match the SID for the 2.4 and 5Ghz bands of the router (WiFi and WiFi 2)?

The TP-Link TL-WN881ND PCIe x1 802.11a/b/g/n Wi-Fi Adapter should be perfectly capable of seeing the 5Ghz band. That it is not doing so seems to me to indicate a problem with the Router or WiFi card.

Since the ROuter is new I would suspect it is the cause of the problem. Can you install the old Router to see if the problem disappears or not?

Hi there

@teletheast

With the 5GHZ band some equipment can only see the lower channels and lower bandwidth option -- so on your router adjust the 5GHZ channel accordingly. Other equipment randomly disconnects as well.

I noticed this when trying to connect a new Amazon firestick -- it picked up the 5GHZ band but kept saying "Out of Range" until I'd adjusted the channel and bandwidth and control sideband settings on the router for the 5GHZ wifi.

This seems the best compromise --I found problems with some equipment if I selected the 80 Mhz rather than 40 or 20 MHZ bandwith option and if I'd also selected upper rather than lower control sideband. The default setting was ch 140, bandwidth 80 Mhz and control sideband setting was upper.

This setting seems to work well for all my gear that can access 5GHZ wifi -- and the range is greater too !!!




All working fine now.

Most domestic routers can be accessed via 192.168.x.1 where x is usually 0, 1 or 2
