Windows 7: Slow Wifi Speed

Does your router has the latest firmware? I would definitely verify this.

Also, you may try WPA encryption, see if it makes any difference. Sometimes, when you change encryption even lowering it to WEP, then upgrading it to WPA2 would do magic.

Hi,

Thanks for your response,

Would this make any difference though as the card is working fine in safe mode but not when running in windows normally. I'm sure you are probably right but just wanted to check first?

Also the router is currently running on the latest firmware.


Edit - have tried changing the security settings still the same.

That might be an issue, if you're speed is way better in Safe Mode and not Normal Mode your system might be infected.

Let's do some minor Virus and Malware scan. Please install MSE Free, then scan your computer, no need to post the logs. Also, install SuperAntiSpyware and run it as well.

Test your connection after.

Thanks for your response,

I did all these before uninstalling the AV/Firewall software. I dont think its an infection as I can connect through Ethernet fine in windows but its just the wireless card that I have slow speeds with. It seems like something is interfering with the card in windows because it works fine in safe mode.

Hi, wizkid.

2xg asked me to take a look at your thread since it was suspected the problem may be a malware issue. If you are completely comfortable that it is not a malware issue, fine. However, you may wish to consider an on-line scan. If so, please do the following:

Please go here to run an on-line scan from ESET.
  • Note: It is easiest if you use Internet explorer for this scan. (If you use an alternate browser, it will be necessary to download the ESET Smart Installer)
  • Turn off the real time scanner of any existing antivirus program while performing the online scan
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the ActiveX control to install
  • Click Start
  • Make sure that the option Remove found threats is unticked and the Scan Archives option is ticked.
  • Click on Advanced Settings, ensure the options Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  • Click Scan
  • Wait for the scan to finish
  • Use notepad to open the logfile located at C:\Program Files\Eset\Eset Online Scanner\log.txt
  • Copy and paste that log as a reply to this topic.

Possible malware issues aside, please realize that when you boot to Safe Mode, certain generic safe drivers (i.e., VGA drivers) are loaded instead of the drivers for your hardware. Also, even though you tested disabling unnecessary services, nonetheless, the system still loads only minimal services when booting to Safe Mode. Thus, it is not unexpected that your connection would be faster.

I spent a bit of time researching the ASUS WL-138g v2 Wireless Network Adapter PCI Card and discovered that slowness issues with that particular card is common.

Sample at ASUS WL-138G V2 recognized as airport card but running slow (Note: there are suggestions in that thread that adjusting the antenna made a major difference.)

When I installed the WL-138G v2, my results are around .4 to 1MBps.
