Windows 10: I have a Realtek 8811CU Wireless network adapter and it randomly disconnected from my PC,...

I haven’t had wifi on the PC for 2 days now, I have tried everything that it says to do online.

Realtek wireless adapter randomly disables

I have a laptop with a Clevo P150EM motherboard and Realtek RTL8723AE wireless adapter running Windows 10 Professional.

I am occasionally able to connect to a wireless network and connect to the internet but the adapter seems to randomly disconnect and disable then enable itself after roughly 20 minutes. When this happens I am unable to reconnect to the network without rebooting the machine.

Sometimes when I try to connect to a network, the connection will be attempted then the adapter disables and enables, stopping the connection from happening.

I have updated all drivers, uninstalled and reinstalled latest drivers, tried everything suggested by Microsoft including turning off the turn off adapter to save power option.

There are several other devices connected to the router that work fine, including Windows 10 devices.

I have exhausted the options presented in the Microsoft forums, most of which just point to solutions in the link above.

Does anyone know how I can get the wireless adapter to maintain a stable connection.

 

Internet Randomly Disconnects: Ethernet Network Adapter Keeps Disconnecting

My internet keeps randomly disconnecting throughout the day. Its a Dell (Windows 10Pro 22H2 - Dell Precision 5770) with Network Adapter: Realtek USB Gbe Family Controller Ethernet. I tried these steps below, no resolution yet:

One thing I noticed, everytime the internet randomly disconnects, I go to Device Manager, and notice the Realtek Network Adapter has totally disappeared from the list (with no option to reenable, even after finding it in Hidden devices).

I have to go through these two steps in this order to bring back internet.

1. Restart Computer
   
2. and then Restart Modem Router. ( I do restart modem by unplugging/plugging back in).
   

If the ethernet disconnects, Restarting the Modem won't work. Neither will Restarting Computer work. It has two be those two steps above in that specific order. I'm curious if having this resolution path, to understand why ethernet adapter disappears. If you can help target or specify why its occurring?

Already attempted this: and the problem still continues

1. Updated Dell Drivers
   
2. Windows Update
   
3. Network Adapter Troubleshooter
   
   
   
4. (a) Network Reset and (b) tried manually uninstalling/reinstalling network drivers separately
   
   
   
5. Tried manually downloading the software drivers at Realtek website Oops!
   
6. Replace cable just in case, but the other computer in home does not have internet randomly disconnect
   
7. Tried:
   

1. Disable these three in Device Manager: (a) Energy Efficient Internet (b) Green Ethernet (c) Wake on Magic Packet
   

I use the modem with another computer, and no issues whatsoever, until I got a new computer.

Note: this is different from previous question, since its looking at a problem/diagnosis path, rather power management settings.

 

My Realtek 8811CU is extremely slow

I recently had fiber optic fitting in my house, I was very excited as my previous Internet wasn't great. I am now getting speeds of 280Mbps consistently throughout the house apart from my gaming PC which gets an appalling 3.4Mbps. I assume this is done to the WiFi adapter I use. I have the Realtek 8811CU Wireless Lan 802.11ac USB.

Things I've tried already:

• Resetting the network
  
• Updating the network drivers
  
• netsh winsock reset
  
• netsh int ip reset
  
• ipconfig / release
  
• ipconfig / renew
  
• ipconfig / flushdns
  

There is no difference in using 2.4ghz or 5ghz, and I cannot move my computer nearer to my router.

Is there anything else I can do or do I just need to get a new one?
