alright guys, heres the back story. The apartments I live in are fairly new less then two years old. They contracted out all their IT and comm/data guys for awhile but there were some managment issues/changes and well they no longer contract out for their network admin/maintainance people. Which is all fine and dandy (their not firing me either way) but every few days I'll go to get on the internet and nothing. I'll have to go through and tell my TCP/IP settings to change to some static ip (total shot in the dark on which ones arent used by the way) so for a few days my computer will be happy with 192.168.1.67 and I'll have to change it to 192.168.1.154 and so on.
I have no reason why it does this, so I asked around. No one who works here seems to know anything about computers less what TCP/IP means. I tried everything I can think of to even find the d*mn router my place is hooked up to.
ipconfig /all will show

Ok so I'll go to type in 192.168.1.254 in ANY (IE6, FireFox, Opera) browser and nothing.
Ping it, I'll get 0% loss. Approx round trip times 1ms-3ms

Still shows 192.168.1.254, yet still cant view it in any browser. Cant even get a hit, it will almost time out and then send me to my browsers seach page and then whine about how it cant find the specificed address.
So I try Netstat -r
[code:1:22f9b8e0c8]C:>netstat -r
I played around with arp -a but I honestly have no idea what it does so I didnt includ that here.
I only barely tried searching for 10.0.0.x ip's howver I did try to change my ip to 10.0.0.5 with a subnet of 255.0.0.0 and looked around that way only because I remember hearing somewhere that if your on a different subnet you wont be able to find the router and blah blah.
I dont know what else to do. I'm not a networking major though so I very well might have either missed something or just didnt go about it the right way. But hopefully someone here can give me a hand!!!
Thanks in advance
I dont know why I didnt think of it before but I decided to go into IE and hit up
https://192.168.1.254
guess what? I got the login prompt for the router (I believe) the funny thing is on the prompt where it would normally say the piece of hardware's name it says "level_15 or view_access" ???
So I went through the normal barrage of users and pw's and every time I'd end up with a 401 Unauthorized error. So is this actually my router or did I just come upon some catch 22 in networking?
Thanks

They may be using a Sonic Firewall and a hub and or switch. Hotels use hubs because they are cheap. If its a hub you should be able to pick up all trafic with a packet sniffer.

Well I have found the MAC address of the router, some of the TCP ports. Most importantly
port 22 ssh - RLP
SSH-1.99-Cisco 1.25
I tried to open it up in telnet and guess what?!

I got that fair, however they have changed the default user and password.

Cisco SDM supports a wide range of Cisco IOS Software releases and is available free of charge on Cisco router models from Cisco 830 Series to Cisco 7301. It ships preinstalled on all new Cisco 850 Series, Cisco 870 Series, Cisco 1800 Series, Cisco 2800 Series, and Cisco 3800 Series integrated services routers.
Still nothing. Any idea's?
On a side note, I did go looking for a physical router but alas could not find it.
Your appartments sure weren't skimping if they went Cisco Is DHCP addressing avaliable? or are you having to assign a static to get an IP at all?
Do you know of anyone else in the building who is having this problem as well?
How big is this appartment complex?
If it is huge and supplies its tennants with internet there must be a data/server room hiding somewhere. Is anyone on or offsite in charge of the network right now? Better make sure with the owner of the building before messing with their equipment to much
It looks like they are probably using a Cisco integrated services router. No way of telling what model without logging into it or finding it though.
