SZ770N problems with wifi ?? (wifi-N)

i got a sz770n and supposedly it has the wireless-N protocol on the wifi card..

however, i got a linksys wrt350n at home, and can not connect to the wireless with the Mixed mode setting (for N support)..

if i drop my router to BG-Mixed mode, the wireless on the sony works fine.


Anyone else have those problems ????

 

Your not alone in having experienced these issues with the 4965AGN and that router you own.
Based on the threads i have read it looks like the problem could be happening because you might not own a dual band router.

after reading those last night, it all made sense, and i never thought to search for the router / wifi card combination. it would have lead me right to the issue..

Intel® Wireless WiFi Link 4965AGN
Data rate will not exceed 54 Mbps when WEP or TKIP encryption is configured



Symptom(s):
Client device's WiFi data rate will not exceed 54 Mbps when Wired Equivalent Privacy (WEP) or Temporal Key Integrity Protocol (TKIP) encryption is configured.

Cause:


The IEEE* 802.11n Draft prohibits using High Throughput with WEP or TKIP as the unicast cipher. If you use these encryption methods (e.g. WEP, WPA-TKIP), your data rate will drop to 54 Mbps. The Intel® WiMAX/WiFi Link 5350, Intel® WiMAX/WiFi Link 5150, Intel® WiFi Link 5300, Intel® WiFi Link 5100 and Intel® Wireless WiFi Link 4965AGN client drivers connect using a legacy IEEE 802.11g connection rather than failing to connect altogether, which complies with the IEEE 802.11n draft.


Solution:


1. Contact your WiFi access point (AP) or router manufacturer to download the latest firmware version, or to obtain information on particular models supporting High Throughput.

2. Disable 'packet bursting' or similar feature that may be enabled on the AP or router.

3. Configure the WiFi client device's profile to use Wi-Fi Protected Access* (WPA2-AES or WPA2-TKIP). You may also choose to configure an unsecured profile, but this option is NOT recommended.

4. Configure the AP or router to match the client profile.

Note: Some AP or router manufacturers may not have updated firmware solutions for devices sold outside of the United States.
