Title: losing internet connection?
Post by: Mark R on March 24, 2004, 02:43:19 PM
i have installed sme 6.01 without a hitch.
but after a while my internet connection goes down.
i can still access all the sme apps from within my lan, but cannot access the outside world.
it seems that my link to my router goes down.

Does the fallowing help?
ifconfig eth1 down
ifconfig eth1 up
There are some network cards, that drop the connection when the connection goes down (in example you unplug the lan cable) and do not come up on their own (tey do not autosense the network cabling, because they do not have 'media-sensing'). In example early 3c900 cards had such behaviour as I have experience.

Other type of problems could be related to unresolved names because of DNS failure :(

why do you need the netgear router?
SME can act as a router, too.

cheers

Some Netgear routers have a bed habit of dropping internet connections. Try doing a Google search for your router and check out some of the discussions on this problem, there are a lot of them.

I've got a similar problem, no Netgear though.

SME 6.01-1 hooked directly to my Toshiba PCX2500 cablemodem with TWC Road Runner.

ifconfig eth1 down|up does NOT seem to resolve the issue.

Every few days I end up doing a shutdown -r now and cycling power on the cable modem to 'fix' the problem.  Interestingly, I get the same IP address after each restart.  Quite annoying...  With power management enabled it was much more frequent - every few hours or so.  I'll try entering in the DNS information as mentioned above.

As a relative n00b to Linux, where should I be looking for clues on this?
