Vista Home Edition - internet connectivity issues

hpm
Folks,

I recently purchased a Compaq laptop and have been trying to get it to connect to the internet consistently. When I use it at home with my Linksys router and cable modem, it fires up just fine. However, when I take it off-site to my office and plug directly into the cable modem there, it will NOT run. I get an IP address that starts with 169... meaning that even though I have set it for automatically getting an IP address from the DHCP, it doesn't assign one. Other folks can plug into the modem and they have NO problems. They are also running Vista Home Edition. I have tried "hard coding" an IP address into my system but that doesn't work either .... any ideas where I should look next?

Thanks!

    The following is a suggestion from Peconet Tietokoneet:

    You might try one other trick:

    For network adapter driver, enable TCP/IPv4 and TCP/IPv6, click configure.

    Internet Protocol v.6 is enabled by default in Vista, but may not be supported by the office network. Check out True Blue's post of 19 June'08:

    Control Panel > View Network Status and Tasks > Manage Network Connections > Local Area Connection

    right click Local Area Connection > Properties

    > uncheck TCP/IPv.6
    > uncheck Link-Layer Topology Discovery Mapper I/O Driver

    > uncheck Link-Layer Topology Discovery Responder
    click OK > restart

    Refreshing configuration by using ipconfig /renew
    When you troubleshoot a TCP/IP networking problem, begin by checking the TCP/IP configuration on the computer that is experiencing the problem. If the computer is DHCP-enabled and is using a DHCP server to obtain configuration, you can initiate a refresh of the lease by using the command. ipconfig /renew in the command window.

    Click Start, run and type in cmd and press Enter.

    At the Command Prompt type ipconfig /release and press Enter.

    At the Command Prompt type ipconfig /renew and press Enter.

    Does this sequence of commands accomplish the same thing as clicking repair in the LAN icon system tray?

    Yes, sort of, except at a lower level. It's a command directly to the hardware and leaves Windows out of it. Because, as we all know, sometimes Windows gets confuzzled!

    Keep Portland Weird? Many natives think it's due to influx the past decade from Southern California (Venice Beach types)...

    Personally, I prefer the Land of the Tumbleweeds, where one can gaze across miles of unobstructed rolling prairie and hear the meadowlarks chirping.

    Normally cable modems store the MAC address of the device that was last connected and should be rebooted (turned off or unplugged and then powered back on) when connecting a new device (or you could wait potentially quite a while). You may also want to inspect the configuration of the modem itself which is normally accessible through a web interface which could be accessed by a computer than can successfully obtain a lease.

    I have done several of the suggested fixes: release/renew ipconfig, rebooted the cable modem, used the "fix connection" button on Vista networking and "unchecked" the IPv6 protocol buttion. BTW, another laptop using Vista Home Edition has both protocol buttons clicked -- IPv6 and IPv4 -- and no problems connecting to the internet.

    I have even fired up a different laptop using exactly the same physical connection, gotten the IP address and used THAT as a static address for the VISTA laptop that won't connect. No joy.

    The "office network" consists of plugging directly into the cable modem so I don't have a router or switch in the way. In theory, I should get an IP address directly from the connection but my address ALWAYS starts with 169 ...

    The thing that drives me nuts is that the non-connect ONLY happens with this laptop at THIS location. When I take it home and use it there ... no problems. When I take it off-site to a different real estate location/office and connect in their computer room ... no problems.

    Because of the law of troubleshooting, "the amount of time you spend trying to fix a problem is inversely proportional to the size of the fix", I believe I am overlooking some small or simple ... any other troubleshooting tips?

    thanks!

    there should be a local explanation.

    1) 2.4GHz radiofrequency interference (cordless telephone base station)

    2) RF interference (motors, fans, etc.)
    3) Shielding (metal cabinets, metal cubicle enclosures)
    4) Wrong encryption password
    5) Wrong encryption protocol enabled
    6) Low signal strength (too far from access point)

    You're right - when things aren't working, go back to the basics and don't overlook the simple stuff.

    Hope this helps.

    Not using the wireless connection. This is a hard connection using CAT5 cable. Yes, I have swapped out cables, used one cable on multiple machines, swapped ends, etc ...

    Would encryption be a problem on a wired connection? None of the other PCs I have seen on this connection have encryption enabled.

    Sorry, just frustrated as to why the gremlins decided to pick on me.

    checked the DHCP Address Range of the Modem. It may be set to allocate only a small number of Addresses and if they are already in use there is nothing left for your connection. Check the IP Address of the other PC's in the Office and assign it a Static IP on a number above the rest.

    < I am not in front of a Vista PC at the moment. Check to see if you can set the IP from the Alternative connection if it is there. >

    I did try to use a static IP address from another machine but that didn't work. I didn't think to try one "out of range" but since I am getting the IP address directly from the cable modem/provider, I don't know that I would be able to check their address range ... suggestions as to how to do that?

    Thanks! hpm

    Try another Fly Lead. That is the Cable that connects your PC to the Modem/Router, wall outlet or Hub/Switch. Or remove the Cable from a working PC and plug it into yours.

    To access the Modem would require UserID and password. It is normally accessed through a Web connection by typing in its IP Address. Unless you have the required information you won't be able to view or make modifications. If you don't have this information you will have to get in touch with the person that looks after it.

    Also try this but follow the instructions.

    Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers

    I used to have a Compaq laptop that would have problems connecting to the internet after windows update would run. Try doing a system restore and see if that fixes it.

    0. I can easily solve this problem if I have more relevant data about how that wireless switch/router is configured.

    1. Just because they can does not mean you can. It did not assign you an IP may be because it's setup to assign IPs only to specific MACs that are authorized to be on that wireless network (MAC filtering). For example, only company equipment are allowed to be connected to company internal network locally. This is how the wireless switch/router can be locked down to lockout unauthorized users (perhaps users such as you who are bringing home equipment to work and may potentially infect the entire company with viruses, malware, and spyware).

    2. Have you asked your company IT staff about how that particular switch/router is configured? Have you asked them to configure your notebook access?

    3. It's also possible (I don't know how plausible) that your attempt to connect has cause the network connection to exceed a preset limit.

    4. If the wireless switch/router is setup for DHCP, you're wasting your time in setting it up using static IP. It could have been setup to allow only a block of IPs that are authorized to be on that router, or it could have been setup to limit the number of IPs assigned to a preset limit.

    5. It could have been set to use VPN so you'd need to be authenticated thru a VPN thru that network first before you're allowed to be on that network. Again, have you asked for official help? If not, why not?

    6. I would not post more detailed information here since any such info may be used to get into your company network. But if you don't, it'd be difficult to help you out.
