The last few weeks my WAG 160N stops accessing the internet perhaps four or five time a day. Pulling the power plug for 20 seconds and reconnecting it usually gets it going again - until the next time.
Also I have noticed the internet light - the right hand LED - is red every so often. The gateway is behind my PC so I haven't been able to see if it always correlates withe the lack of connection.

Try the following steps:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Gateway setup page.
# Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your routers main/ basic setup page).
Here is the link for determining and setting up the correct MTU size: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=
Then check the status…

That' very interesting, many thanks. I don't know why the internet disconnection has only recently been a problem - I *have* had the occasional disconnect in the past but now it's every hour or two.
I followed the link, but the ping only returns the message that -f is not a valid parameter. So I have reduced the MTU to 1400 and will see what effect if any this has. I will report back!

Yes, I used the info from http://www.dslreports.com/faq/5793. After going "down" quite a bit I increased the value until it only just "bit" then added IIRC 28 and set that. So far I haven't been having any internet dropouts at all.
Have you any idea why this should suddenly become apparent, after several years with the setting on the default 1500?
And would that be the reason for the red light on the "Internet" RH LED on the router?

Take the back-up of all the settings and reset the Gateway. Steps to reset the router:
Push the reset button on router for 30 seconds, turn off the router wait for 30 seconds and then power it on. Power light should blink when you perform the reset process.
After reset, reconfigure the Gateway and then check the connectivity status…
The Internet LED lights up and stays on when there is a connection made through the Internet port. It flashes to indicate network activity over the Internet port.

I did all that before I started this thread, but to no avail. Your advice about dialling down the MTU did the trick - I haven't had any diconnects for the last two days since I did that, so it appears to have been the problem. Why it should have started when previously, with the same settings, is a mystery. And the function of the red light I can't discover from the user guide.
Thanks for the solution!

Back to the drawing board!
After some time with a lower MTU as suggested, and all being well, the internet disconnects are back. I tried reducing the MTU by stages, eventually right back to the minimum - which made the page delays unacceptable) abd have now gone back to 1000. Something somewhere isn't working properly, and I dodn't know enough about it to know what's wrong - the ADSL connection, the LinkSys gateway or whatever.
