Have D-Link G604T router/modem and want to connect my TP-Link TL-WA501G Access Point. Problem is router is not automatically assigning an IP address to the TL-WA501G Access Point. The D-Link gateway is 10.1.1.1 whereas the TP-Link AP gateway is 192.168.1.1 how do I get into the menu of the TL-WA501G?

Connect the router to the modem with an ethernet cable, CAT 5, 6 or 7. Try amazon.

What are you using for Internet connects? do you have the Access point connected to a Router. or is it connected to the Cable or DSL modem. I will need more information to complete this. If you have a router is is set to give an IP address or do you have a static IP? If it is set to give a Dynamic ip change the access point to recieve ip address from router and same with computer. If your connected directly to the Modem with the access point and you only have one IP address it will be used by the access point and not allow the computer to connect.
for more help please provide your internet (DSL, T1, CABLE) if you have router,  how it provides IP, and how access point is connected to it.

Wi Fi needs a router with Wi Fi that is transmitting its identity with an ssid http://www.webopedia.com/TERM/S/SSID.html
Where are you trying to connect lumia 510 to. Is it at home do you have an existing internet router with several ethernet ports on the back of it. If yes then you need a Wi Fi access point or Router.

Basically what you have done is plugged it in but did not set up the router on a static or dynamic IP address.

Once you have established the IP address of the router and it is recognized by your ISP device (DSL, Cable, Satellite modem ....etc etc.) then you have to decide which device will be the DNS server and assign IP address to all the wireless devices that connect to it.


Lots of things can be wrong. You need to follow the steps on the set up link i gave you properly and in the correct order

First, did you pay the bill? Unplug the IPS modem, remove battery, if applicable, unplug TP Link, shut down computer. Ckeck ALL cables reseat, Replace battery, plug in ISP modem, allow it to selftest, plug in TP Link, allow it to selftest, Reboot computer. If you connect ISP Modem directly to PC and it doesn't ID your IP address use this: http://helpdeskgeek.com/networking/release-and-renew-an-ip-address/ To assist you. If this doesn't work contact your ISP provider . Try another Wireless Access Point. My ISP, Xfinity, drops from time to time , for no appearent reason, due to a number of outside difficulties.

Hi,
Assign Static IP address to the netwok

Look for MAC Address Clone setting on the router's Setup Page. Just enable that and power cycle the router and modem
