Lease keeps expiring.....wtf?

Just moved into my apartment and my roommates upstairs get their internet fine. I will get mine for a while, and then it wont work. If i restart the computer (only way to get it to work) it starts up again. I checked the event log and it said my lease expired.

Now, do i have to call the internet company because we get internet for free through the apartment complex (no router or modem is what im getting at here)?

Thanks for your advice
 
Probably the best bet to call. Also you can see the details of DHCP with the command "ipconfig /all", it will show your your lease time.

Next time it happens try "ipconfig /renew" before restarting to see if you can get an address.
 
thanks spidey. i had done the ipconfig /all command earlier, but it was when the computer wasn't connected (or my lease expired, whatever).

this time i did it while it was connected and it shows a lease time of ONE HOUR. what the hell? That's just retarded.

the thing that gets me is that nothing works unless i restart the computer, i cant just repair or anything like that.
 
Ok - so ipconfig/release and then ipconfig/renew doesn't work? If so your tcp/ip stack might be hosed, search MS for "repair tcp/ip stack" - certain parts of the stack not working are normally a sure sign, in your case it's DHCP.

The reason for such a low lease time is if they are running really low on addresses and/or have machines restarting a lot, so to accomodate that the lease time is set really low.

1 hour lease times are fairly common...after a portion of the lease has expired, its up to your computer to contact the server that initially granted it to renew the lease.

as spidey said, sounds like a tcp stack or some other local pc issue.
 
Our cable only has a 1 hour lease time and it works just fine. My router just renews the IP address when it expires, no packet loss or anything. I've actually had the same IP address for 8 months now.
 
this is so irritating. after it expires, it shows it disconnect and then reconnect again (takes a long while), but nothing works. It always gives it the same IP address...and it's automatically assigned. Its one of the AAIPA things, which historically for me means it doesnt work. i guess if it takes too long to connect it gives it an AAIPA which basically does nothing at all.

guess ill just keep restarting.
 
do you have any other spare nics? did you update your current drivers? i know you tried the LSP fix, but what about some others?

start > run > netsh int ip reset
MG Winsock

is your computer the only one with this issue? you hinted to your roomate having similar problems.
 
Why don't you just forget the headache or this and just plug a router into that port and your computer into the router. Problem solved? Although if your computer is not automatically renewing the IP, your NIC has a problem.
 
dont feel like getting a router. i forgot to mention that there is a switch upstairs...at least thats what the internet company calls it. It looks like its connected properly, and it should have no effect on the downstairs (basement, mine) computer, but the odd thing is that the computer that is hooked up TO the device has the internet working fine, but me and the guy upstairs (where the switch is supposed to fix or whatever) dont have correctly working internet.
 
I'd also take a look at the functionality of any cables, routers, switches and NICs between you and the furthest upline you can reach.

What's the IP address of your DHCP server? Don't need to post the whole thing if you don't care too, just the first six digits or so. I'd be shocked if there wasn't already a router in your building's network. Especially if you are getting "free" Internet.

so can i just make it static?
 
"the odd thing is that the computer that is hooked up TO the device has the internet working fine, but me and the guy upstairs "


What is 'TO the device'...is the guy upstairs plugged directly into the modem?
if so, with what type of cable Ethernet or USB?

Id think everyone should be plugged into the 'switch' not just you two guys downstairs
 
er, static ip worked...i dont know if thats okay. There is no modem. There are two people upstairs, me two floors down. The switch should involve just them, not me, right?

There are about a dozen things that would cause that. My guess is still stack because that's a classic behavior. A particular part of the stack doesn't work.
