Sorry I was busy. I finally get around to this. Please see below for my current setup.
>>What wireless modes are you using? Under Setup/Wireless/Manual.
>>Try single mode G or N or mixed G and N?
My current setting is Mixed 802.11n, 802.11g and 802.11b. My other modes are
1) G only
2) N only
3) B only
4) Mix G and B
5) Mix G and N
>>Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Currently set to 20Mhz
>>Try setting a manual channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the >>channel is clear.
Right now I have Enable Auto Channel Scan ON and Wireless Channel is at 2.437GHz - CH 6
>>What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi >>adapters don't support AES, so you might want to try TPIK only or Auto.
My security mode is NONE now because I'm using MAC filtering. Should I select a security mode in addition to MAC filtering?
>>Turn off WISH, and WPS under Advanced.
Don't see these options under Advanced
>>Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under >>Advanced/Advanced Wireless.
Already off for Short GI and WLAN Partition. Extra Wireless Protection not found.
>>Enable WMM Enable Under Advanced/Advanced Wireless.
Already set
