E3000 optimal wireless config to maximize speed/stability?

    I have a linksys e3000 running the (Tomato Firmware v1.28.9054 MIPSR2-beta E3000 USB vpn3.6 firmware) but i am having some issues getting decent wireless speeds on both the 2.4Ghz and 5Ghz radio's and i'm wondering if the default settings aren't doing me any favours, but have no idea what to do to optimize them as quite a few of the settings are unfamiliar to me.

    i'm not expecting miracles on the 2.4Ghz front at the reason for going dual band was all the people crowding the bandwidth around me, but although for the most part the status page shows 150mbps for the 2.4Ghz and 300Mbps for 5Ghz, every time i try and connect on either frequency the connection rate on the router status page nosedives down to around 54Mbps or lower and the wifi card can only connect at around those speeds.

    i understand on 2.4Ghz with all the neighbours, but there isn't anything at all using 5Ghz locally except for me.

    i've done a search, but i can't see anything that might help me get all the settings correct.

    does anyone know what the optimal settings should be?

    thanks in advance.

    Leaving 2.4 out of it for the moment, you should be able to connect at 300 if your client wireless supports it. IF your signal is strong enough with the router (around -70 or better). Check that first.

    You might also want to see this thread where someone else experienced "slow throughput" and achieved much greater speeds.

    When I Enabled the Wireless setting "Interference Mitigation" and changed the Tomato default "NONE" to "WLAN Auto" I noticed an improvement in the wireless RSSI and Quality numbers for the wireless devices running on my network. I believe on the original Linksys firmware the default is Enabled and set to "WLAN Auto" --- not sure why it is disabled in Tomato.

    That's interesting, pharma! I actually found the exact opposite, and in my builds I set the default mitigation to "none". With this set, the signal strength on RT-N16 and E3000 (2.4GHz) with tx pwr set to 60 is approximately the same as a WRT54GL set to 150. But - with it enabled (WLAN AUTO), I got around 6 or 7 dB less and the tx power setting didn't do anything much. I guess it depends what's on the channel, which we basically have no way of knowing for sure.

    I have had quite a lot of mail which said that the suggestion to use "none" improved signal strength, which was the reason for my changing the default setting.

    Whatever the explanation, experimenting with this setting at the same time as tx power seems to be a good idea :cool:

    (Reminder - Don't forget to select a country that enables the use of higher powers - such as US or Singapore. Some countries set a very low power in the wireless driver.)

    I agree Toastman ... it definitely pays to experiment with various settings. One suggestion to people who are having wireless/bandwidth problems might be to change to the original Linksys default settings (*) to see if there is any improvement.
