why does my wifi keep dropping only on my computer
i have a realtek rtl8811au wireless lan 802.11ac usb 2.0 network adapter in the usb slot in my pc and it seems that everytime i try to play games, the wifi drops but it says the device is still working. i have just had enough because i simply cant play a game i like. it seems that the only way to deal with it is to unplug it then plug it in to a different port. this is the only solution i have but it only last for 15-20 min before it cuts out again. is it the adapter, computer or wifi in general, (i have 100mbs of internet)
does the adapter get overly warm or even hot (check carefully) between the start of game playing and the wifi drop?

try using a usb extension cable to connect the wireless adapter to your pc.

then raise the wifi adapter up and away from the pc. 

reposition as necessary to determine if wifi service stabilizes.

may also help keep the wireless adapter a bit cooler.
i assume your new router is wireless?

limited access with wireless usually means you don't have a valid ip address assigned. you need two things for a working internet connection. 1. you need a physical connection, known as layer 1 and layer 2. 2. you need a logical connection known as layer 3.

if you've got the limited access message that means your laptop has a working wireless connection at layers 1 and 2. what you don't have is the layer 3 connection i.e. an ip address.

there could be a number of reasons why this is happening. i would suggest that you start by powering your pc down - shut it off completely not just hibernate it or just shut the lid. next power down the router, pull the power cord out of it. let the router sit unplugged for about 2 minutes. power the router back up......wait about 2 min more. power your pc back up.

learn how to use the command line command "ipconfig". you access the command line via the accessories folder on windows. when you get the c:/> prompt - enter the command "ipconfig" hit enter. in the group of stuff on the screen you want to see an ip addess assigned to the wireless interface. when you get the limited access message the first thing you want to do is check to see if you have an ip address assigned.

if the above trick doesn't work, then i suspect there is something wrong with your network configuration on your pc. if you take your laptop to a starbucks does it work there? Your card is ok. There is interference between the router and your computer.  

  

1. The router or the PC may be "hidden" behind a metal cabinet, refrigerator, etc.  

2. Move router higher  

3. Microwave ovens and some cordless phones (not cellphones) that use 2.4GHz will interfere with the 2.4GHz WiFi signal.  

4. Point the router antennas in-line with the direction of the PC.  

5. Move the router closer to the PC. hi [@tino52](/u/tino52)

however, there might be other factors that don’t show easily - e.g. radio noise like other wifi or bluetooth devices, badly filtered appliances, quality of your power supply, external circuitry, …

i agree with this, it could be any of a number of things. you are c… only thing i can think of is to maybe reflash the firmware. that is where i'd start as well. osi...
so:
1. physical link (maybe check the patch panel and the cabling that's involved in connecting to the computer, maybe swap cables and try a usb to ethernet adapter to rules the nic out.
2. data link - check the switches and switchports on the way. maybe try to use different portts
3. network - most likely not an issue if all the other computers are working fine...
etc.
but this is pretty much it: it could be a random drop or a glitch. if you've got the item and nothing else is wrong with the game, enjoy! If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.  

OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.  
If the battery drops to an unacceptable charge level then the battery needs to be replaced It could be a problem with static discharge , if so do the following.


1. Disconect the power cord


2. Remove the battery


3. Hold down the power button for 30 seconds , then release for 30 sec and then hold down for another 30sec


4. Plug in power ,replace battery and power on laptop.


If this causes no Joy try this.


Remove memory and reinstall one stick at a time, if there are more than 1 dimm of ram, try each stick in each slot one at a time to see if the memory is ok and to determine if one of the memory slots is bad.


Hope this helps i've been having intermittent access problems also.  i changed the dns servers my wifi router is using to google's - 8.8.8.8   it seems to have resolved my issues. it is solved. did all of the above and unplugged the att u-vers router. after it rebooted all seems well.
