Apple Airport Express Ip Address
set up a network to accommodate both wired and wireless connections. My setup includes a Motorola Surfboard SB6141 cable modem, an Ethernet switch, and two Airport Express routers. I recently had my old switch go bad (it was actually an old wireless router acting as a "dumb" switch), so I replaced it with an actual 5-port Linksys switch. Now I cannot get anything to play nicely. If I shut everything off and then power up first the modem, then the switch, airport express default ip address I have Internet connections on the wired PCs. If I turn on the Airports after that, the main Airport Express won't be given a valid IP by the modem's DHCP server and instead ends up with a 169.254.x.x address. If I shut everything off and then power up first the modem, then the Airports and the switch with all PCs disconnected, the main Airport Express will grab a proper IP address but will refuse to connect to the Internet even still. Connecting the wired PCs after this results in them self-assigning invalid IP addresses. The main Airport is in DHCP and NAT mode, while the second Airport is acting as a WiFi extender so it's in Bridge mode. Placing both routers in Bridge mode breaks the Internet connection via WiFi, but it doesn't make sense to me that the first router should work properly in DHCP/NAT mode since the modem is already running a DHCP server, and in my limited understanding it seems to me that this would either create conflict or at least a subnet on my network, which I don't want either. What, if anything, is wrong with my network setup, and how do I correct it? wireless-networking switch bridge airport share|improve this question asked Apr 28 '14 at 23:36 Nate migrated from serverfault.com Apr 29 '14 at 15:55 This question came from our site for system and network administrators.

After switching to the cable modem (Motorola https://forums.mediacomcable.com/index.php?topic=720.0 SB5100), I reconfigured the AirPort to share a public IP address and act as the DHCP server. When I do this, the AirPort restarts with an error stating that it has an invalid IP address, which sounds like it is not receiving a proper IP address from the modem. When I connect a laptop directly to the modem, it will access the Internet without a problem. I have tried power cycling everything in every combination with no luck. Am I supposed to manually enter the IP address for the AirPort? I'm not sure how to proceed any further.

I can clear that out from here though. As long as the router's setup to pull all required info from the modem, we should be able to get that resolved. Will you PM me your

It also had an issue about not being able to find the DNS servers but I think I fixed that. My old (spaceship) Airport works somewhat but I would like to get the old one straightened out without paying Comcast $80 to give me the correct configuration. The modem is an Arris TM402P.I've tried unplugging everything and plugging it all back in in every different order I could think of but nothing seems to work.Any ideas?Thanks in advance. 0 Kudos 14 REPLIES Posted by EG 09-20-2012 11:22 PM Connection Expert View All Member Since: 12-24-2003 Posts: 52,204 Message 2 of 15 (25,204 Views) Re: Airport Extreme IP Address Issue Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Report Try using the recesssed reset button on the rear. You'll need something like a bent paper clip or a pen tip. Depress and hold in the recessed reset button on the rear until you see the front panel indicator lights begin to cycle, then release. Now give the eMTA the time it needs to re-sync. I am not a Comcast employee, I am a paying customer ju
