Turn your TX Power to 84. If you feel like you need to go higher, then go higher. I don't experience the TX errors that are mentioned in one of those links.

I just threw 90 at mine. Set my Beacon level at 90. And set the Broadcom chip @ 225MHz. All good

Aside from just signal quality issues from having it too high, increased mW directly relates to heat output. There's a certain point for each router model where it can't efficiently dissipate the heat as fast as it's being produced. This can really affect your router's longevity.

Get high-gain omni antennas for another decent boost.

TX Power - 125
Beacon Interval - 100
CPU Clock - 225Mhz.

Meh. I've had mine at 125 TX Power for 4-5 years. If this thing hasn't blown up yet... I don't know when it will.

Did you do the initial flashing with a mini version,then the full version? Did you reboot everything modem,router etc?

Here's the instructions from dd-wrt if you don't have them already.

It will not do you any good to go above 63 mW if you are using default antennas. Default antennas usually run around 2.1 dBm. Once you add 63 mW and 2.1 dbm, you are going to end up with 100 mW.

The reason for not going above 100 mW is the clients will not be able to get back to the access point, or they will just not have good signal. Omni direction antennas are limited to 100 mW in the US, so you will not find any laptops that do over 100 mW.

It was stated earlier in this thread signal strength does not effect speed, and this incorrect. Signal strength and speed go hand and hand with wireless.

If you set your router to 125 mW and you are using 2.1 dBm antennas, you will end up with a total output power of 202.30 mW. This is double the power your laptop can do. You can have great signal from the router at the laptop, but the signal from the laptop to the router will still suck.

Edit: Something else to add. The wireless footprint for an omni directional antenna looks like a donut with the antenna sticking up through the donuthole. The more power you push from the router, the more you flatten that donut out to look like a pancake. So depending on where you have the router positioned, you could also be hurting yourself by chaning the wireless coverage area. You should only be effected by this in a two or three story house.

Thanks everybody for suggestions but I went back to factory firmware and all is well now.

This is the second time I tried ddwrt with same results. First time I tried it, I thought it was the router (it was a cheap one) but this time I know it is not the router, it is the firmware.

I just didnt see what people see in this firmware, I really want to use but 2 times it left me hanging. Freeze ups, frequent disconnects, really bad signal strength. It was just down right terrible...

That's to bad,cause dd-wrt is really good 3rd party firmware.Did you flash to mini version first,and was directly connected to the router(not wirelessly)? I'm not sure if your router is supported but there is tomato firmware too.
