Hey there all you good folks at DaniWeb !!!!!!!
Please hang in there with me because I don't know all the correct terminology for this stuff but I will try my best to explain my problem.
I have a 5mbps Ethernet cable that comes in my house. I have that plugged into a hub, so I can use my computer and also work on other computers. The hub has places to run 5 computers at once.
Usualy I can connect a computer with an ethernet cable, hit "REPAIR" and the computer automatically changes the computer that I'm working on to connect to the internet.
Right now I have a HP Pavilion a 1250n. For some reason, it has 2 different places to be able to hook a Ethernet cable. I have plugged my Ethernet cable into both places, at different times, hit repair and yet this computer will not connect to the internet. I get the mesaage.....Windows could not finish repairing the p[roblem because the following action cannot be completed:
Renewing your IP address. For assistance, contact the person who manages your network.
I'm trying to get this computer hooked up to the internet so I can update my AVG Antivirus, Spybot Search and Destroy, etc...
I'm pretty lost when it comes to LAN and related subjects.
Any help will be greatly appreciated !!!!

Nice quick fix from — power-cycling often clears this sort of problem. A short explanation and a few practical checks will help if this happens again.

Hubs are simple electrical repeaters (they do not hand out IP addresses). DHCP assignment comes from the modem/router or another DHCP server on the network. Windows "Repair" runs a series of steps (adapter reset, DHCP release/renew, ARP/NetBT clears) and will fail if the physical link to the DHCP server is down or the upstream device has locked up. Power-cycling reinitializes the link and the DHCP state, which is why your connection returned after the hub was reset.

Quick troubleshooting checklist (in order):

  1. Look at the link/activity LEDs on the computer port and the hub port — no lights usually means a physical problem (bad cable, dead port, disabled adapter).
  2. Swap the cable and try a different hub port to rule out a bad lead or port.
  3. Temporarily connect the PC directly to the modem/router (bypass the hub) to see if DHCP works. If it does, the hub is the likely cause.
  4. On Windows run these commands from an elevated prompt to see current settings and force a DHCP request:
ipconfig /all
ipconfig /release
ipconfig /renew
  1. If renew fails, try a manual static IP in the modem/router subnet (pick an address outside the router’s DHCP pool) to test connectivity.
  2. Check Device Manager for the NIC status and update drivers; disable NIC power-saving options.

A small unmanaged switch is a cheap, more reliable replacement for an old hub. If multiple machines must share one ISP IP, add a router so every device gets proper DHCP/NAT. This explanation should make clear why ' power-cycle worked and what to do next time.

The hub isn't assigning an IP to the computer, try unplugging the hub, plugging it back in after thirty seconds and trying it on the computer again.
