ICS keeps disconnecting

Dell / INSPIRON 6400
December 1, 2009 at 12:45:25
Specs: Windows 7, E6600/2Mb
I have a PC connected through a wireless connection. It's the only way I can connect to the net for purely physical reasons. ( I'd need a cable 1/2 mile long to connect without using wireless, but that's a story for another day).

So I just tried using Internet Connection Sharing on this PC ( running Windows7 )to connect to my laptop ( running Windows XP ) using a crossover cable. Everything is fine.....for about 20 mins or so, and then I loose connection between the two computers. The only way I can reconnect is to disable the ICS, and then re enable it. If I just plug out the crossover cable from the Laptop, and reconnect it, I get the limited or no connectivity issue.

I've tried various things like using another cable, turning off all firewalls/antivirus, and still can't get the connection to stay. When it's working, it's fine.

Any help would be very much appreciated.

Hi wanderer,

The crossover cable I have for a few years. It was a standard CAT5 cable, but I modified it back then, and it never gave me any trouble before. You think it's dodgy?

Anyway, here are the results of the ipconfig. At this stage it's working as I've just connected up.

usually ics defaults to 192.168.0.1 on the host

usually ipconfig /all includes this info also

Thanks for your help wanderer.

I did an ipconfig/all and here are the results. I knew it should default to 192.168.0.1, but it tells me that it is going to configure it to the 192.168.137.1 , and wasn't sure if it might have been something new with Win7. However, it's not even that it doesn't work, it's that it terminated the connection after a lenght of time. I read somewhere that theres an idle timeout of 5 mins, but that's with win XP, and I tried to keep the connection active to see if it stays connected, and it still seems to disconnect me.

I've checked that it's always left on with both the wireless and network card. I've even tried with the laptop plugged in, but it still knocks me off. Baffling me now, this is. Not giving up though

IP Routing Enabled. . . . . . . . : No

This should be yes if ics is engaged.

You have hamachi and a virtual network interface 2. That could be confusing windows.

In post #5 I don't see the ethernet card with a ip address. I see the wireless but not the wired nic which was active in post #2

Kinda thinking its the nic card that is dodgy though I would try a different crossover cable before replacing the nic.

It says media disconnected AND it says you have done a static ip assignment.

Yeah, the static ip I don't really have a choice with. Didn't notice it saying Media disconnected untill you pointed that out. Strange, cause it was connected, and working.

I'll uninstall hamachi, ans see how that goes. And I'll change the ip routing to yes. I'm at work at the moment, and won't get a chance to do anything untill later.

The NIC is built into the motherboard, but there also a second one, and I've tried that too, with the same results.

Thanks again for your guidance. It's very helpful.

You edit the registry to change routing from no to yes? You have to do the whole ics package not regedits.

Start fresh by undoing what you have done then run the ICS setup or download and run analogx proxy.

First of all, Thanks for your paitence wanderer.

yep, your right, I edited the registry to change the routing from no to yes.

So I undid that, rebooted, and started fresh. I downloaded, and installed analog proxy, but can't get it to work. I set the ip in it to 10.0.0.1 and then configure the remote comp to 10.0.0.2 with a subnet of 255.255.255.0 . I tried the default gateway as 10.0.0.1 and nearly everything else, but still no joy.

So I Tried ICS again. ( it's only a matter of ticking the "Allow other network users to connect through this computers internet connection" under the sharing tab of my internet connection on the host comp), unless I'm doing this wrong somehow?

Anyways, even after a fresh start, things are the same. However, I've discovered it disconnects me, and then reconnects after about 5 mins. It seems to keep up a cycle of this

Try a different nic card, not one of those built in. Analogx proxy should have also worked. Since both don't I have to think hardware or corrupt registry.

I couldn't fix windows registry to see a cdburner correctly recently. But a fresh install sees it just fine. Go figure.

Strange that alright. However, I did manage to get Analog proxy to work. Had to use proxy setting in Firefox, or Explorer. Skype the same, but it works fine now. Only thing that doesn't work is when I try to enter details into a page. Like a search query or when I tried to reply to this post, and had to log in, but couldn't. Probably has something to do with https or something, but as far as getting disconnected goes, it's all good. Thanks a lot for all your help wanderer. I wouldn't have got any satisfaction at all if I didn't get your guidance.

Thanks again
