Router -> Modem Connectivity: I am fine if I'm hard-wired to the modem but if I connect wirelessly through the router I can't get WAN. I can get the modem page wirelessly. This just started tonight. I was connected wirelessly just fine for months.

Solution:

Step 1:
Make sure the that router is connected to your modem with an ethernet cable via the router’s internet (WAN) port.

Step 2:
Unplug the modem from its power source and make sure that it's totally turned OFF. Then re-plug the modem to the power source.

Step 3:
Unplug your router’s power supply, wait for 10 seconds and then plug it back in. This will cause the router to reestablish communication with the modem.

If you still cannot browse the web, contact your Internet Service Provider (ISP).

Make sure your router's WAN port is set to dynamic IP. If the light on the front doesn't glow/blink for the WAN port, try a different cable. If a different cable doesn't work it's probably toast. :( This problem appears to be directly linked to the relationship between the WAN port and the modem. Given that the devices can connect to the router, but not internet, it has to be the WAN. Sometimes if the modem goes out it will send too much voltage through to the router and fry the WAN. Had that happen to my parents router. If the above doesn't "fix ya" then try a different router.

Worst case, you might have to put a wireless card in your PC and bridge the modem (wired connection) to the wireless card and broadcast for your wireless devices. At least until you get a new router.

Need more INFO... getting disconnected from what ??? the LAN (Local Aria Network) or the WAN (Wide Aria Network) ???, in other words do you loose network connectivity or internet connectivity ???, is it trough wired or wireless connection ???, if it's wired LAN connectivity, check/change the cable from the router to the computer, if it's wired WAN connectivity, check/change the cable from the router to the ISP's modem, if it's trough wireless check for RFI (Radio Frequency Interference) or EMI (electromagnetic interference) move the unit away from any electrical device or radio transmitters, change the frequency of the unit to an other frequency than the default one, etc...

Good luck!

Flashing lights on a router are routine - they indicate connectivity and traffic.

Seems to me the simple answer here is stay connected by wire. Wire runs much faster than wireless. Wireless is 10 <> while wire is usually either 100 or 1000. If you have to have wireless, do a hard reset on your router and also reload the drivers. Check with the manufacturer for any soft or firmware grades they may offer. If you find a firmware upgrade - make sure you understand the instructions before you start. If you fail in this department, you will have to replace your router. Had you given a little more information on this, I could have done better with links and such.

Modem brand/model?
Router brand/model?

Type of internet connection coming in to your modem, DSL, Fiber, BroadBand (Satellite/WAN)

Double check your physical connection. It should be this way

Modem > connected to Internet Port of the router
PC > connected to port 1
Laptop > can be wireless

Now you must power cycle your router and modem. Turn off router first then modem. Wait for 30 seconds. Power on modem first, then the router. You must configure the wireless settings on your laptop it doesn't connect automatically.

No. A router has 2 main interface types WAN (for the internet connection side, and LAN (for the home network side) the 'LAN' side often has up to 4 ports and wireless connectivity for the home network.

The most common routers available at electronics retail use a CAT-5 connection for the WAN ports and the LAN ports. Your DSL modem/router uses a phone line input for it's WAN port, which uses a signal type that is incompatible with the cable modem output.

If COX doesn't offer a router with the cable modem package, you can go and purchase and common brand of home networking router, and attach it to the output of the cable modem.

** Try this steps

- Check physical connection (Modem=WAN Port, Computer=Port1) *should be hard wired connected*
- Power cycle modem and router for 2 minutes (to turn off the modem and router)
- Check web browser for Internet connectivity

* If nothing happen reset the router for 15 seconds and try the steps again.

Try this. It should renew your configuration between your router and your internet provider:

Step 1 Log into the web-based configuration by typing in the IP address of the router (default:192.168.0.1) in your web browser. The username is admin (all lowercase) and the password is blank (nothing).

Note: The 192.168.0.1 address is NOT on the internet. It is the address to the router itself.

Step 2 Click the Home tab and click the WAN button. Dynamic IP Address is the default value, however, if Dynamic IP Address is not selected as the WAN type, select Dynamic IP Address by clicking on the radio button. Click Clone Mac Address. Click on Apply and then Continue to save the changes.

Step 3 Click on Status. Under WAN, Click DHCP Renew. If it does not get an IP address or times out, then continue with Step 4.

Step 4 Power cycle the cable modem and router:

Turn the cable modem off (first)
Turn the router off
Leave them off for 2 minutes**
Turn the cable modem on (first)
Wait until you get a solid cable light on the cable modem
Turn the router on
Wait 30 seconds

** If you have a Motorola (Surf Board) modem, leave off for at least 5 minutes.

Step 5 Follow Step 1 again and log back into the web configuration. Click the Status tab and click the Device Info button. If you do not already have a public IP address under the WAN heading, click on the DHCP Renew and Continue buttons.
If you're still getting no connection to the internet, another alternative (before chucking the router) would be to reset it to factory defaults, and run through the setup process again, from scratch.

My advice and personal experiences with both wired and wireless connectivity, is if you wish to share files and internet connection, purchase a combined Modem/Router and not a seperate router to work along side your original modem. Your modem will send your router an ip address in turn your pc is sent one from your router and can get complicated; keep it simple! These are much easier to set up and control as one unit and if there are ever any connection problems you will know it's either a setting or a modem/router problem and not have to wonder ; is it the modem?; Router? settings? etc. As there are frequent loss of connections both internet and LAN it makes sense have one peice of equipment to maintain.
