WiFi in desktop is not working properly, Asus PCE-N53

[jabelone]

Hello,
After having a buggy installation of windows 8 on my desktop PC (custom built) I did a clean install of windows 8.1. The main issue was the wireless was not working properly. It won't connect to some networks, it won't even display some networks. When I try to connect to a network (and it actually works) the connection is always at around 5.5 Mbps and is unusable. It always drops out and doesn't work properly. I am running windows 8.1 on an Asus P8Z77-V LX motherboard, i5-3570k, 120GB Samsung 840 SSD, 1TB WD HDD, GTX660 and corsair 16GB RAM.


I am using an Asus PCE-N53 PCIe WiFi card (WiFi g/b/n dual band) and a Netgear Wireless Router (WiFi n). A while ago on windows 7 it worked completely fine. Now most of you are probably going to ask me about the drivers, I have completely removed and re-installed the most up to date drivers from the Asus website multiple times. I have a cheap (L-Blink or something) PCIe WiFi card and it does EXACTLY the same thing - with it's generic drivers.

Could it be a windows 8.1 issue - ie how it handles the wireless connection? I am at my wits end am starting to get extremely frustrated. I have spent almost two weeks trying to get this to work and would really appreciate any help.

Thanks, Jaimyn

My guess is that it has to do with win8.1 and/or the drivers. I really do not have a solution but the wifi chip on the Asus card has another producer and if you can find what it is they may have better/newer drivers.

Thanks for the help, but I really don't think it's the drivers as it is doing EXACTLY the same thing on the Asus WiFi card and on some el cheapo one that uses a generic driver. I have also tried, generic windows drivers, proper asus drivers and the automatically installed windows drivers - they all do the same thing. I will look up that chip though and try another manufacturers drivers and see if that helps. Thanks!

I am encountering the exact same issue with the PCE n53. If you happen to find a solution, please post it.

Here is the solution. it helped me to get 300 mb/s with ASUS PCE N53.

1. Download latest ASUS driver for PCE N53 (for me it was ASUS PCE-N53 driver 5.0.35.0 for windows 8.1 64 bit). It's a ZIP file. Extract it. There will be 5 files. Make a back up copy to another folde in case of something goes wrong.
2. One of this 5 files is RaCoInst.dat. Open it with Windows Note editor. Now you have to find a line like this "RUS=10001000". For me it was RUS as I'm in Russia. Find your own country and change "10001000" parameter to "11101110". For me it became like this "RUS=11101110". It activates 802.11n. Save the file and lose it.
3. Go to Windows Devce Manager, find your wifi adapter and dele it. Refresf the list. Windows will find a new device. Now you have to install the driver for this device. Do not let Windows make it automaticaly, manually find the folder with the file we eddited (RaCoInst.dat).
4.Reboot your PC (maybe it's not neccesary).
5. Got to windows RUN, type in "regedit". Find the following string:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\XXXX
XXXX in this line is a sub folder. I have 7 of them: 0000, 0001......0007. For me it was 0000 folder. Click on it and you'll see a lot of parameters on the right side. Now find and edit the folowing lines:

AdhocNMode - 1 (to activate "N" in Ad-Hoc mode)
AllowBW40InBGBand - 1 (to turn 40MHz on)
AutoReconnect - 1 (autoreconnect)
CountryRegion - 1 (allows wifi chanels from 1 to 13)
SmartScan - 1 (multimedia/gaming mode)
TXBurst - 1 (speeds up the connection)
and finally
WirelessMode - 5 (for me it was 5. Try which is better for you)
0: legacy 11b/g mixed
1: legacy 11B only
2: legacy 11A only
3: legacy 11a/b/g mixed
4: legacy 11G only
5: 11ABGN mixed
6: 11N only
7: 11GN mixed
8: 11AN mixed
9: 11BGN mixed
10: 11AGN mixed

I also changed these lines:
CountryTxPwr - I set it to 20
CountryTxPwr5G - this HAS TO BE "1118181e"


6. Reboot your pc. Connect to wifi AP.

Good luck.
