You would use a LAN port on the AirPort Extreme base station. Normally, a PC configured to handle DHCP would connect automatically. Check the network and TCP/IP settings to begin with. Exactly which operating system (Windows?) version are you using?
Have you configured the AirPort Extreme base station correctly (via AirPort Utility)? Are there other computers connected to the base station (wirelessly)?
Also, which Internet Service Provider is it? Modem type/model? Since you can establish a connection directly through the modem, we cannot rule out that the ISP somehow detects the MAC address of a connected device, or that the modem for a reset has to be disconnected for a certain time.
Thanks for replying. The thing is, I don't really know what the settings should be.
Check the network and TCP/IP settings to begin with. What should they be? We have tried manually putting in the IP address.
Exactly which operating system (Windows?) version are you using? Windows 7
Have you configured the AirPort Extreme base station correctly (via AirPort Utility)? We loaded airport utility on the PC and think it is configured correctly, but then again I am not really sure what it should be?
Are there other computers connected to the base station (wirelessly)? Yes, there is 1 iMac, 1 iPad, 3 iPhones, 3 PC laptops that connect wirelessly with no problem to the base station. And also an Apple TV. And an Apple express to extend the wireless network.
ISP is Cogeco. Modem is Arris cable modem.
Is the Windows 7 computer set to obtain an IP address automatically?
Since you have several other devices properly working, the AirPort Extreme base station as such seems to be correctly configured.
Would it be correct to assume that the Arris modem in question is a plain wired cable modem? The reason for asking is that some wireless models appear to require enabling bridge mode when using a third-party (in this case Apple) router. See also
I have confirmed the model of arris modem is tm722. I have read the entire manual and don't see anything about wireless or needing to bridge. I have also configured the LAN connection properties to select IP address automatically. Not sure what to do from here. Should I be doing anything with airport utility on the PC? Should I be talking to cogeco support? Thanks,
Yes, that appears to be a plain wired modem (unlike, for example, the TG862 gateway). It looks like you have connected and configured everything correctly. The modem would be connected to the WAN port of the AirPort Extreme base station, and the Windows 7 PC to a LAN port. The Ethernet cable type (straight-through or crossover) should not matter. BTW, which AirPort Extreme base station model is it?
Just for a test, do you have access to another PC (possibly with a different Windows version) that could be connected to the LAN port of the AirPort Extreme base station instead? Alternatively, if the Windows 7 PC has a DVD (or CD) drive, you could try to start and run that computer directly from an Ubuntu live DVD or CD (without installing a system onto the hard disk: http://www.ubuntu.com/download/desktop/try-ubuntu-before-you-install) in order to check whether a connection via the LAN port in question then is possible.
You could of course contact the ISP to double-check the setup. However, as indicated earlier, all the wireless devices seem to function as they should, so there would not really be a reason to suspect anything wrong here (unless I have overlooked something completely). You may also want to ask them about whether the MAC (Ethernet) address of the base station somehow is of any significance in this context.
Hi, we have now contacted the ISP but they are saying it is the router issue so they were not any help.
The airport extreme is one of the first models, with 802.11g. Not sure of the number.
I have not been able to check another PC yet.
I will try now the ubuntu process. What if the connection via a LAN port is not possible?
