Losing wireless connection

    My system is constantly losing its wireless connection. Same with my Acer Aspire One netbook and my Xbox 360. I have a WRT54GL router that I've flashed with Tomato 1.25 SpeedMod. Most values are set at default, except I've recently upped the Transmit Power to 70 mW. This had a moderate effect in wireless signal, as shown in the Device List page and in the program InSSIDer. I have my wireless set on Channel 1 as there seem to be a lot of neighbours in the area on Chan 6 and 11. I have security set at WPA2 with AES. My main system is an overclocked Q6600 on an Asus P5Q-E motherboard with 4gb ram. Both my main system and netbook are running Windows 7 RTM, but I had the same problem when they were running Vista Ultimate before. Any tips/suggestions?

    Thought I might go ahead and clear my NVRAM and reflash my firmware. I only did this after upgrading to 1.25 SpeedMod, and through the menu Administration->Configuration->Restore Default Configuration->Erase all data in NVRAM memory (thorough). Is this same as the hard reset 30/30/30 instructions I found on the dd-wrt website?

    Try not to set the transmit too high. If the signal is too loud, your client devices will not be able to "hear" the signal clearly, as there will be too much noise. I would not recommend setting the transmit to 70mW, especially if the devices are in the same room.

    okay i'll try bringing transmit down, but dont' really want to go all the way to default

    If you haven't already done a hard reset after flashing to tomato, definitely do so.

    For sure do a nice reset. For kicks. Put the transmit power to 28mW and see if it keeps you online. Pretty much have the same setup as you. With a Wii added and no trouble with wireless. If you had the problem before like you said you did. It could be because of all the traffic around and having a high transmit power causing the issue.

    I just loaded Rod's 1.25 speedmod and tested it. No issues, all stays connected. I think it is more likely to be an issue with your wireless card compatibility with Tomato. This is known to happen with most Intel, some Atheros cards and some D-Link USB adapters (Ralink chipsets) on occasions. The easiest way to check this would be to see if a different client has the same problem using with a different wireless card. You have a few devices already, but they are all known to be troublesome ones, I believe quite a lot of people on this forum have had issues over the last year or so. You didn't mention what your main PC uses for wireless.

    But, before doing anything else, I'd see if the problem persists after turning off all encryption. If it's OK, try WEP, work your way up, some encryption methods have issues too.

    Also, to erase NVRAM: Administration/Configuration/Restore default configuration/erase all data in NVRAM (thorough).

    Thanks guys I'll give that a try. I'm wondering if I should try flashing with the ND driver version of speedmod, but I'm not quite certain what that is. My main system has a Linksys WUSB54G wireless adapter, which is Ralink RT2500 chipset based. My netbook has an Atheros based chipset.

    Great to hear, I'll give Victek's a try. So far Speedmod's is running quite stably and I do notice better wireless signal running the ND driver (this time I erased nvram before and after flashing). The true test will be if I do some heavy traffic such as uTorrent. I thought the Speedmod was better for P2P traffic though, should Victek be the same?

    I believe Victek's version also includes all of the Speedmod changes.
