Thibor15c slowed me down?

    With the latest official linksys firmware I was able to routinely hit over 20mbit/sec during wireless file transfers between my two computers. Now I top out at 17mbit/sec since switching to thibor15c. Is there a setting I'm forgetting? I turned afterburner to on instead of auto and it didn't do anything. I'm using a version 2 linksys wrt54gs.

    Thanks for any tips.

    It could be due to the fact that the official Linksys firmware defaults to 84 mW for wireless transmit power wheras Thobor's default is 50%, or 42mW. Now, I'm not 100% sure if this would even be the cause, but it's possible. Try setting Thibor's to 84 mW and see what happens

    Are you sure? I think the default value is 28 mw.

    I don't think the router's Tx power has anything to do with it. To the best of my knowledge, all stock firmware prior to V5 defaults to 28mW. V5 and above defaults to 84mW according to BrainSlayer.

    1) Thibor's firware do a bit more than the stock firmware. Maybe turn off whatever functionality you don't need.

    2) Make sure Frame Burst is on. I found this to have more influence on wireless speed than Afterburner. Also in your adapter's driver setup. They sometimes call Frame Burst "Xpress" or something similar.

    3) Afterburner would only make a difference if your adapter is also Afterburner capable. If not, Afterburner on the router may actually slow you down. (Your 20Mbps sounds a bit low, so I don't think you have an Afterburner adapter).

    4) If you use authentication/encryption, test with different combinations. Some firmware seems to perform better with X, while other perform better with Y. Generally though, WPA/AES seems to impose the least speed penalty.

    5) Most importantly, test and retest if you're fanatic about the speed. Two test run right after another, with identical setups, both settings-wise and physical environment-wise, can yield vastly different results.

    6) Read the "Wireless tweaks/hacks" or whatever it's termed (I forget the exact name) on this site. See if you find any useful hints there.

    Thanks for the suggestions HennieM. Yes both the router and the adapter are speedbooster capable but the adapter is the usb pos and I'm regretting not buying a card. I'll play around with various settings. I switched back to the latest stock firmware and the speed is still only around 17mbps so it wasn't the thibor firmware.

    I tried with and without encryption and got the same results so that isn't it. Not sure what's going on with the sudden speed drop.

    I put together a fairly comprehensive list together of things to check as the second post in this thread. Maybe something there will help?

    Well I switched back to the latest thibor, but I didn't use secure easy setup and my speeds are back to where they were before, possibly better. :)

    Manual security settings with wpa/aes was the key. Oh, I also reinstalled the adpater software. Anyway, thanks for the tips guys.
