How can I tell if my router is truly bricked?

This is an FAQ for which we do not have an article yet.


I bricked my router? Now what?

There's a lot of variables in answering this question and we don't have articles to cover all the different situations. But, for now, first verify that it's truly bricked. Then see: Recovering from a bad flash.


Is my router supported?

If you have to ask, probably not. See Supported Devices
Linksys WRT54G v7.0 models are not supported and probably never will be.


What router shall I buy?

In short, the Buffalo WHR G54s is the cheapest 100% compatible wireless router. For more information see Recommended Devices


Where do I download firmware?

http://www.dd-wrt.com/dd-wrtv2/downloads.php


What's the difference between the different DD-WRT versions?

See this


How do I install DD-WRT firmware?

Make sure you have a compatible router, then see Installation


How do I upgrade my firmware with TFTP?

Flashing with TFTP must not be seen as the standard procedure for flashing: only use it when you are specifically told to do so (for example in the specific instructions for flashing your brand or type of device). Normally, the GUI flashing method should be used; it should be perfectly adequate for any standard situation. See Installation


What's the default username and password?

Starting with v23 SP1, the default username is root and the default password is admin.


How do I access the router's settings?

If you have DD-WRT installed, your router's settings should be accessible by opening a web browser and typing in http://192.168.1.1/ in the address bar. If you have changed the LAN IP address on the router, you'll need to type in the correct one instead. If your router doesn't have DD-WRT installed yet, try http://192.168.1.1/ or http://192.168.0.1/ or else consult the manufacturer's documentation. Whether you have DD-WRT installed or not, make sure your computer has an IP address in the same scheme as the router. Try accessing the settings using a network cable instead of accessing them wirelessly. Try clearing your browser's cache. Also see this.


Why can't I access the web configuration for my router?

If you've read the previous question and it didn't help, then your router's HTTP Daemon might not be running. See "Regaining Access".


I'm having lots of transmit errors. How can I fix that?

Try setting the Ack Timing to 0. If you have the the transmit power turned up higher than 84 mW, turn it down to 84.


How high should I set the transmit power on my router?

Somewhere around 84 mW is considered to be the best setting for maximum power with minimum noise. The forums have had discussions about what power level is safe, with little conclusion. Use common sense and don't set the power higher than you really need to. If you're trying to get more range, consider using a different antenna and make sure you have a clear line of sight, two of the most critical factors in your router's range.


How can I increase my wireless range?

Many factors affect your range. Consider getting a good antenna and try setting up your wireless devices with a clear line of sight. Best range is achieved by using one directional parabolic dish or yagi antenna and then disabeling the other antenna on your router. Try increasing your router's transmit power to 84 mW.

TODO: Place the FAQ here, provide two versions. The first being a guided FAQ version for the less technically inclined to find the answer to their question, as well as a complete listing of all questions seperated by categories for the more advanced users.
