Title: slow DWA-125
Post by: arnec on July 17, 2013, 06:17:26 PM

I am running a wireless network with a D-Link ADSL2+Modem (DSL-520B,) a D-Link DIR-601 router connected to a Windows 7 machine with sp1 and a D-Link DWA-125 receiver on Windows xp Home Edition Version 2002, sp3. The "advertised" speed of 150 Mbps is seldom met, generally only after I reinstall the DWA-125 receiver. Then the receiver slows to 72 Mbps.

Any ideas how to fix this problem?

• What Hardware version is your router and modem? Look at sticker under router.

• Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz Routers only: Try single mode N or mixed G and N?
• Channel Width set for Auto 20/40Mhz.
• Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channel) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
• Any cordless house phones?
• Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
• If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
• Enable WMM Enable (http://forums.dlink.com/index.php?topic=50738.0) Under Advanced/Advanced Wireless.

3rd Party Security Software Configurations

• Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
• Turn off all devices accept for one wired PC while testing.

What is the reported connection speed seen on the DIR-601 under Status/Wireless?
Ensure that you are using the latest 125 drivers from D-Links main web site.
