LAN problem

[mar77a]

I have a WRT54G router and each time any of the laptops connects to the LAN through wireless, internet connectivity goes down for a good ... 2 minutes (for everyone) and is then restored (especially my brother's Sony Vaio). Any idea?

I used to get it at my parents place. I'm not sure how i fixed it but maybe adding MAC and a static internal IP(the computers liked to switch ip all the time even when browsing the net thus loosing connection) to each device can help.

Oh and if possible get the latest firmware.
and use some sort of protection if you haven't sone that yet.


EDIT: This might help

you need to tweak the wireless setting on the router itself in order for it to send out proper signals....access the router using http://192.168.1.1 "admin" is the password...
go to the wireless section and select channel 11. save settings....then go to the advanced wireless settings and reduce the beacon interval to 50 and reduce the RTS and fragmentation threshold by 40 each.....hope this works for you

or this:

This from the Linksys web site which is reasonably easy to use and has some
good info.
"If your wireless signal is intermittent, then you are most likely you are
experiencing 2.4 GHz interference. You will need to try switching channels
and changing the SSI D on your WRT54G. The best channels are 1, 6 and 11. To
switch channels:

1. Using a computer that is plugged into the router directly with a
network cable, open a web browser.

2. In the “Address Bar� type http://192.168.1.1 and press Enter.

3. A box should appear asking for a “User Name� and a “Password�.
Leave the “User Name� field empty, and type your WRT54G router password into
the “Password� field (the default “Password� is admin) and click the OK
button or press [Enter].

4. The WRT54G “Setup� page should now appear. Click onto the Wireless
page.

5. When the “Wireless� page loads, you should be on the Basic Wireless
Settings sub-section.

6. Look for the “Wireless Channel� option. The default channel is set
to “6 - 2.437GHz�. Change it to either “1 - 2.412GHz�, or “11 - 2.462GHz�.

7. Click on the Save Settings button toward the bottom of the page to
save changes. Click Continue when prompted to reload the page.

8. The channel of your WRT54G has now been changed. Restart your
wireless computers so that they can automatically connect using the new
channel.

9. If you still experiencing interference using channels 1, 6, or 11,
try switching the router to the other channels as well (2, 3, 4, 5, 7, 8, 9,
10) and find one that captures a good connection".

The WRT54G's SUCK, or at least their firmware does.  Check the linksys site for an update.


The only time I ever recommending using WRT54G units is if you put dd-wrt or some other linux-based/third party firmware on it.
