They are splitting the bandwidth. Turning them off might help, especially if the DSL is not "high speed DSL" and they are running applications like updates, etc which use the internet.
You may also have some roadblock in the 802.11b to the 802.11g transmissions, the "g" being the newer standard.
Upgrading your router may make your connection more reliable. If your connection is noticeably weak all the time, variable, being dropped often in your own network, upgrading to new technology omnidirectional routers and corresponding notebook cards will enable better signal coverage and give you a more stable and stronger signal.http://www.netgear.com/products/details/WPN511.php
More Ram will not increase the maximum DSL connection speed you have but it will increase your computer's ability to make maximum use of the connection speed for the reasons below.
More RAM will help your computer load pages faster because XP, if that is what you are running, works much better with 512 anyway, and part of your 256 is being drawn off for your graphics adapter.
Graphics intensive or poorly designed pages take more time to load and make the load on your graphics adapter more severe. In a notebook the graphics adapter usually uses shared memory vs a separate video card which may be installed in a desktop that has its own ram and especially under load takes ram that the rest of the system could greatly use. Of course the speed of the processor comes into play too.
More ram will also give your computer more speed because it won't have to write to the page file as much, (or retrieve from the page file as much), the page file being slower because it a section on the hard drive - vs solid state memory (ram) which is much faster.
Another thing to try would be to reboot the entire system - the DSL modem (by unplugging it and disconnecting it from the phone line for a few minutes), unplugging the router, and of course shutting down all the computers using it.
To reboot, plug the modem back in, then the router, then boot the computer/s.
