I have used this router for over a year now.
Everything works on it, wireless, dhcp server, the gigabit switch. But now it cannot pull a IP from my motorola cable modem.
I've reset both devices, the modem and the dlink, reset to factory settings, everything, still won't get an ip from the modem.
I know the modem isn't the issue, as I hooked up an older dlink wireless b router and its working fine, its my backup!
I have the newest firmware and everything.
Any help would be great!
I had this problem with another type of router. If the software is fine and the modem shows no problems, its probably your ethernet port on the router. Alot of routers ports go bad after a certain amount of use. It could have been a defect from start and just started to show problems.
Logically at this point its hardware. You troubleshot the rest. Last thing to point at is the WAN port on the router going bad.

The easiest way I can think of is to shrink the DHCP address pool.
To do that, at least on the model of Actiontec router I have, click on "Network (Home/Office)" the go to the "IP Address Distribution" section of the screen. "DHCP Server" should already be selected, and under that, you'll find "Start IP addresses" and "End IP addresses." Usually, the start will be 192.168.1.2 and the end will be 192.168.1.254. What I usually do is change the start address to 192.168.1.200. That leaves over 50 addresses for normal wireless connections, and I'll general assign IP addresses from the rest of the range as follows:
192.168.1.2 to 192.168.1.9: routers, APs, etc.
192.168.1.50 to 192.168.1.59: printers
192.168.1.100 to 192.168.1.109 for other static devices. (I often find that Blu-Ray players, cable boxes, etc. behave better if they have a static address.)
But really, on home network, I doubt you'll have more than 15 devices that need static addresses, so you could set the DHCP start address as low as 192.168.1.16 if you wanted to.
How did you connect the computer to the router. If you are using a DSL modem it will have a DHCP server in it that is allocating IP addresses across your network. If you added the router to the computer via a hub or network switch what is the computers ip .
address. Remove the WI FI router - turn off P.C and then Go to cmd or dos prompt if windows based system and type in ipconfig and press enter to see if ip addresses are 10.0.0.2 if they are your dlink router uses 192.168.0.1 so you need to make the dlink router ip addressand subnet setting to match the Modem ip addresses of the DHCP server. Change the ip address of the dlink router to be 10.0.0.2 and change the modem to allocate DHCP IP addresses from 10.0.0.10 to 10.0.0.255. Only do this if IP addresses are 10,0,0,1 to 10.0.0.,254 on the desktop p.c with the dsl or cable modem connected.without the router being involved. (you may need to ask the ISP what the user name and password is of the modem and it should be ip address xx.xx.xx.1 so type this into a browser to change the modem settings. 10.0.0.1 or 192.168.0.1 just remember if the modem is 192.168.0.1 so is the Wi router from d-link and you will have an ip clash problem)
. How do you do this by ethernet connection from only the desktop directly with only the Wi FI . router. Go to a internet browser and type in the URL 192.168.0.1 and then change the router ip address to match what the DSL modem DHCP issues..
Page 14 of Router instructions see http://files.dlink.com.au/Products/DIR-615/Manuals/DIR-615_C2_Manual_v3.10.pdf
in the manual it states to use a direct ethernet connection for the setup program but you need to be connected to the internet for it to work but if the IP addresses are wrong or clashing will have no internet. You also want to set the modem as the DCHP server and disable the DHCP server in the set up of the wi fi tand set the WI FI router default gateway as the ip address of the Modem. if any DHCP server options in the WI FI router sert to the modem ip address. .
You shouldn't be connecting the device directly to your ISP, but rather to a modem that is connected to the ISP. The modem will then handle the NAT for your network and your E4200 should be able to pick up a private IP address using DHCP from your modem. Or you can set a static IP on your wireless router as long as that address is available and on the same subnet as your modem. You should also exclude any static IP addresses from being handed out over DHCP so you avoid IP addressing conflicts.
The Linksys WRT54G2 is Cable/DSL router with 4 port switch. It has many features including a built-in DHCP server. By default, it's IP address is 192.168.1.1, username: blank and password: admin.
Plug in the Modem to the Linksys router's Internet / WAN port then plug your PC's to any of the 4 ports (1,2,3 & 4). The Linksys router once turned ON will automatically provide your PC with IP address starting with 192.168.1.xx (x means number from 100-149).
Make sure that known working ethernet cables are being used. Check your computer's IP adress by going to the command prompt. Start>RUN>type CMD then press Enter. Type IPCONFIG and check the IP address (e.g. 192.168.1.100). Check you PC's network adapter if you don't get an IP address from the Linksys router.
You may opt to reset the router by pressing the reset button at the back for 30 seconds if it fails to give out DHCP.
Does folder sharing work through WiFi? Might be that the IP ranges are not in the same subclass network if the IP numbers are not coming from the same DHCP server. Did you check the IP number on Computer B in case of the cabled connection and when it is connected on the WiFi? They should only differ in the last digits, not the first 3 groups.
it seems that ur PC & cable modem configuration is ok, now the problem is with ur router WAN interface configuration. the problem would be one out of 2 - first to check whether ur router wan interface is configured properly to obtain IP address from DHCP (if possible, u can give the static ip address with same series as cable modem) second to check with ur ISP.
If the modem is actually passing out DHCP, then you have to connect the modem to the router 4 port lan side and not the wan port. Give the router a static ip like 192.168.1.2 and you can talk to it and configure the wireless features.
First of all - your ISP has nothing to to with DHCP. DHCP is handled internally by your router (or DHCP server). If you did not configure your router otherwise, it should hand out an IP address automatically. If you ipconfig shows that you have an IP address, then I assume that this address is manually configured. You should set everything to automatic until you know it works. So... Go to your start menu -> Control panel -> Network connections. Right-click on "Network Connections" and choose "open". Look for your "Local Area Connection", if you are wired into the router, or something like "Wireless Network Connection" if you're using wireless. Right-click "Local Area Connection" and choose "Properties". Double-click "Internet Protocol (TCP/IP) and see that both "Obtain an IP address automatically" AND "Obtain DNS server address automatically" are selected. Click "OK" twice and make sure that all property windows are closed. Go to the command prompt and re-do "ipconfig /all" (No quotation marks of course). Check the line that says DHCP server, it should be the same IP as your Default Gateway (your router).
If this does not work for you, copy the result form that command here and I have another look.
If it works, please come back and leave a comment. This might help others with the same problem.
You need to disable the DHCP server on your "slave" wireless router ( the di-524 ). In D-link routers this might be called configuring it to be an "Access point".
When this happens, connecting to the second wireless router should cause your computer to obtain an IP address which is in the range of the first router (that is to say, it will use the first router's dhcp server).
You should be able have your laptop connect with an automatic IP address and have it work.
