Intel 2200BG (and others) Connection problem fixes .... *** I will try to keep this thread updated with any info on connection problems, most of this will of course be related to Intel cards, but there are some others too. There are also many weird scenarios which have been found to cure or relieve connection problems, so it pays to read through the entire thread and experiment, if you are having difficulty. Intel 2100, 2200BG and many other Intel Wireless Card problems Hi All As most of you will know, some Intel cards caused router reboots with the normal driver. Changing to the ND driver cured the reboot problem, but wireless Intel cards could often no longer associate at all. So, this fix is for the problem where Intel 2100, 2200BG, and many 3945ABG cards, can't associate with the router, using firmware compiled with the ND driver. It may also help with the newer Intel "N" cards which appear to be little better than their predecessors. The 1000BGN is one of them, but it seems all Intel wireless adapters can be buggy. [ NB - often, all Intel wireless adapters do not work correctly with the ND driver either. Googling for more information reveals that they often have trouble connecting with many different makes of router. At our local university, most users of laptops with Intel cards cannot use them on the campus]. The Fix: Telnet to the router, log in and enter the following lines: nvram set wl_reg_mode=off nvram set wl0_reg_mode=off* nvram commit reboot (* technically this second line isn't necessary, the router will detect wl_reg_mode and set it to match on reboot). This switches off (or sets to a known state) the redundant features in the wireless drivers, apparently related to 8011h spectrum management additions and not used in these routers, that were causing the problems. It has solved the problem here with almost all older Intel cards, and a few others which previously were unstable such as the occasional Atheros card and Ralink based USB adapters. ( Some related info: http://www.linksysinfo.org/forums/showpost.php?p=331051&postcount=238 ) Tested with the following drivers in Tomato 1.23. 126.96.36.199 188.8.131.52 184.108.40.206 - and later. Here's some information on what 80211h was supposed to do: " IEEE 802.11h is the IEEE standard for Spectrum and Transmit Power Management Extensions. It solves problems like interference with satellites and radar using the same 5 GHz frequency band. It was originally designed to address European regulations but is now applicable in many other countries. The standard provides Dynamic Frequency Selection (DFS) and transmit Power Control (TPC) to the IEEE 802.11a MAC. " Hopefully there will be no other issues associated with this mod. Thanks to "Teddy Bear" for jointly finding this mod and who is incorporating this in his new release, (along with Victek) :biggrin: http://www.linksysinfo.org/forums/showpost.php?p=338578&postcount=127" .

EDIT: June 2009 - Official tomato now also incorporates this mod in v1.25 upwards, it does not have the latest wireless drivers, however, which have some benefits. .
