strange problem with wireless N on dlink dir-615 / toshiba laptop
in [Wireless Internet]
|
From: bitz on 20 Jan 2010 22:14 Should encription like wep / wpa etc be any different if your laptop is connected in Wireless N mode v's G or B etc. Here's whats bugging me at the moment. I have a new toshiba laptop with wireless N capabilities and a dlink DIR-615 router. The DIR-615 has a setting which can force "wireless N only" mode which i turned on just to test out the wireless N speeds etc. With encription turned off it connects ok (speed was 150mbs ..5m across the room). The minute i turn wep or wpa or wpa2 on my laptop wont connect (yeh im putting in the same passcode into the laptop etc!). Yet if if change the router to accept all speeds (ie wireless N G B etc), it connects ok wiht WEP/WPA etc but only connects at 54mbit G settings ..not N. Basically if i use any encription ie wpa/wep etc it wont connect with wireless N settings? Any ideas?

Try either a different router or a different client PC/wireless adapter to prove it off. -- <http://ale.cx/> (AIM:troffasky) (UnSoEsNpEaTm(a)ale.cx) 18:36:37 up 21:38, 6 users, load average: 0.01, 0.02, 0.01 DIMENSION-CONTROLLING FORT DOH HAS NOW BEEN DEMOLISHED, AND TIME STARTED FLOWING REVERSELY

It is a design fault of WiFi radio chip in the router. Maybe your D-link router uses same chip.

"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. Newer Intel� wireless adapter client drivers connect using a legacy IEEE 802.11g connection rather than failing to connect altogether, which complies with the IEEE 802.11n draft." <http://www.intel.com/support/wireless/wlan/4965agn/sb/CS-025643.htm>
