I have a problem with a Belkin Wireless N F5d8233. Selecting Dynamic allows access to the internet via a wired computer but the orange internet light is still flashing and I cannot connect via wireless. If I select PPPoE I cannot even see the modem. My ISP speifies PPPoA but this isn't an option

Connect a LAN cable from Belkin to your laptop/computer's LAN port, open a browser on your laptop/computer and enter the Belkin's configuration URL. http://192.168.2.1
The default PW = blank (just press Enter) You can now change the default admin password.
You can now configure the wireless settings to protect your wireless network and Internet from unauthorized access. Now configure the wireless card in your computer/laptop with the router's wireless settings. To secure your wireless network from unauthorized access, please click on this link and follow my instructions :- http://www.fixya.com/support/r3559128-wireless_router_security

is your computer wired or wireless? Secured? Start wil the ISP modem, unplug, remove battery, if applicable, unplug Belkin, check all cables and connections. Replace battery , plug in ISP modem, allow it to selftest, plug in Belkin, allow it to selftest, reboot computer. If no change contact ISP for further testing, it may be outside.

mine did the same thing, first try reinstalling the drivers, if that doesnt work, try it on another computer to see if it is actually the belkin that is bad or the computer having issues

Change the connection type into Dynamic

1) With direct connect with modem, check the IP address and default gateway.
(I came across such a modem, it gave default gateway as 192.168.1.254)
I also had the doubt of configuring as a dynamic connection
But it won't work!
Contact your ISP to completely bridge the modem and configure the dsl modem as PPPoE connection with correct username and password.
Finally connect the modem to router and do a complete network power cycle, i.e.: Unplug power from router 1st, then power from modem, unplug the telephone line and now do the exact reverse process... Plug back the tel. cable, then power to modem... now WAIT for lights on modem to come back, then plug in the power to router. This will surely work.

Just in case it helps anyone else, I just had to toggle between broadcasting SSID and fixed the problem.

Why did you change it from dynamic to static? My suggestion would be to put it back to dynamic and let it grab a good ip address from the gateway. The other option is to contact whoever managed the network at your apartment and see what they will charge you for a static IP address.
