When my cable goes out my laptop looses connection to the router and my local network
 

When my cable goes out my laptop also looses it's local connection to the router and my local network.

Why? :mad:

do you have a cable modem?

i dont get it, you lost power to your house?

Thats odd. Has to do with the way the ips are handed out on your router I guess. What kind of setup do you have?

ummm, because you get your Internet from your cable company would be my guess

need at bit more detail

Sounds to me like your laptop is being assigned an IP address by the cable
modem instead of the router. Do you have a cable modem that has wireless
support? If so that is probably the cause.

That was kind of my thought also.

this is over your head, read my 1st post again.

yah crocket, brighthouse cable modem, a nice fast one at that :thumbsup to Road Runner

i have it connected to a WRT54G Linksys

I have the laptop set to assign ip automatically.

I'm not sure why you would lose your lan when ever the cable goes out. Even if it was a cable modem/router combo I'd think lan would still stay up but you just wouldn't be able to connect to the internet.

The more important issue would be why is your cable going out? It should really never go out unless you are in a hurricane or they are working on the lines. Does it go out very often?

I have had this problem before. I rebooted by router and IPConfig /release /renew and it fixed it. Have no clue where the conflict was.

You are getting your Internet connection from your cable company and you don't understand why your router doesn't work when your cable goes out?

yah , every couple days it will flicker, sometimes i have to turn the modem & router on and off

it might be in the router

The local Lan should still stay up even if it's not connected to the internet. Computers that are networked together don't have to have internet to be able to talk to each other.

He means that, when the cable internet goes, it so happens that he cannot reach other computers on his network .... don't need internet for that.

I would check to see if all boxes use the same network name ... ( workgroup, ... )

Laptop should be on an ip like 192.168.1.05 or similar. Should be an internal network Ip. Very odd the cable is affecting it.

dude, your making yourself look really stupid, especially for a webhost

Just because the Internet goes down does not mean that my laptop should lose connection with my router.

OK.

now i see why you get bashed so much on here

Is it just the modem that drops out as in loses the solid light and resets it's self? Or is it the cable TV and everything goes out?

It's possible you have a bad line or the signal is just too low maybe it has a extra splitter or two it it's dropping out regularly.

ah, thank you . . . . I'd replace the router

I have issues with my wrt54g too sometimes. I have to reboot it to get back online. You sure its not just the router dropping all connections rather than the cable going out? Like are your connected lights lit up on the modem, but you lose internet?

the line is a tad low, they're suposed to be fixing the problem for 21/2 years

at this point i'm not sure if it's the cablemodem losing it or my router losing connection with the cable modem or both.

Bypass your router for a day or so and see if you lose internet or not. I have that same deal with that router too.

Very similar. I think this is what happens, cable modem loses the internet for a minute or 30 seconds, then my router loses the cablemodem, then when the cable modem comes back to life it cant find the router.

But none of the above should affect my laptop connecting to the router.

I'm not really worried about loosing internet every now and then. BUT my security system uses ip cameras on my network and the pc I connect to this syestem is my wireless laptop.

I don't want my local network going down. :mad:

i can't, my router is my firewall, i don't run any software firewalls

i might gamble and go out and by a newer and better router

Yea the router shouldn't go down.. maybe go and pick up one at best buy or somewhere local and it it doesn't solve the issue take it back.. lol

Routers are so cheap now you can normally pick one up well under a hundered. Also if yea need any help on the cable stuff let me know, I know a thing or two about that, can probably get it fixed for you. You can hit me on ICQ if yea want sometime.

:1orglaugh heh
