Internet pc link and cable link all flashing

Seems to be a dns issue. At least that's what xbox live said. Tried firefox on my pc. Unable to load pages. Ran dos. Released and renewed ip. Flushed dns. These did nothing. Not sure what to do. The router seems like it's functioning properly but as mentioned above, the modem just flashes the three lights

192.168.1.1 is a common/default network router connection. Thompson use a different connection of 192.168.1.254

Don't forget to configure XBOX360 and PS3 through there too. You can even find your WEP key just incase you've forgotten it.

If you use http://192.168.1.254 in Internet Explorer you may be greeted with a box asking for username and password. Both username and password are " admin " in lower-case. Then to retrieve the WEP key click on HOME NETWORK. You'll see your Wireless network and Ethernet network. Beside the WIRELESS you should see WLAN: XXXXXXX (54Mbps) click on that. In the top right just under SPEEDTOUCH you will see OVERVIEW | DETAILS | CONFIGURE | HELP If you click on DETAILS down near the bottom is your WEP key. Hope this helps anyone out there.

Hi,
it just a cable modem. I don't think it does have firewall. It won't block anything.

SOURCE: not getting an internet connection. The pc link

Have you tried removing the AC power from the modem for at least 10 seconds, and then re-applying power? This will cause your ISP to reconnect and reassign your IP address. Then your modem should allow you to connect.

SOURCE: The internet light is flashing on the rca dcm425 i

My RCA DCM425C from Comcast had the same problem when I came home Saturday, 11/14/09 (coincidentally the same day you posted). Had been working fine - cable TV still works fine including On Demand, etc. The Internet light was blinking. Occasionally I'd see it try to work from one light to three or four, but it always came back to one. Called Comcast, they said their side showed "no signal". Sent out a tech today. He replaced the cable modem, reprovisioned it (I guess if I had a backup ready I could have done the provisioning over the phone maybe?)), everything's great. Lasted about a year and a half. When I logged in via http://192.168.100.1, it said it was still in Step 1 of 5 ("Tuning"), and the logs showed a whole bunch of errors on Saturday that stopped after that. Diagnostics would always freeze the built-in web server and require reboot.

Farmville wont load

Slow web pages could be the result of dns server timeouts. Your router is probably getting the dns servers from your Internet provider. (Logging on to the router should tell you the routers dns server IP address).
The PC's could be getting their dns server IP address either from your Server or the 2700HGV router. Disconnecting your server from the network and connecting a PC to the router should test this premise.
Take your server out of equation and see if Internet access and webpages speeds up. later test your speed here ScanmySpeed.com

I am trying to view videos on youtube however, the site loads, the thumb nails load, when i click on the videos i get a blank black box.. no videos load no matter which i click on, i tried updated my flash...

I had a similar problem with my Windows XP which wouldn't support a late enough Internet Explorer and I couldn't use Chrome because my hardware was too old so I used the Firefox browser. It seems Firefox needs a different version of Flash Player. My Internet Explorer was using Flash and for some reason I don't understand that prevented Flash downloading properly or working with Firefox even though several times I uninstalled and reloaded it.
Troubleshooter said to make sure Flash was enabled in the browser options.

I have a moderate nat type on my xbox live. I have a belkin router(model #F5D7130). When I type in my ip address on my web browser it says that the server can't be found. I've tried it on firefox and...

I'm sure you have tried most of these steps but I'm going to list them any way. So we have a complete picture of the trouble shooting process.

To access a Belkin router you must type 192.168.2.1 into your address bar.

A common resolution for this issue is to reset your modem, router, and xbox.

The like below will bring you to Microsoft's official trouble shooting page for this issue.

I hope the info provided helps with your current issue

Xbox can't find network on PC.

the other persons tip is trash mines better ;)

you can go to your routers2_bing.gif website and enter it manually. Type 192.168.1.1 this might be it or try 192.168.2.1 or 192.168.1.100

when it shows your routers2_bing.gif info write it down and then put it in your xbox's network by entering it manually. btw the secondary DNS is just 0.0.0.0 if it doesn't give you two. the gateway2_bing.gif is just your routers ip address.

what else you can do is do port forwarding.
But the xbox is not a static ip address2_bing.gif so it'll change. what you can do is when it says to put your ip address in your xbox put all the numbers the same as the routers ip address BUT DON'T USE THE SAME LAST NUMBER! so like if your routers ip address is 192.168.1.1 you can use 192.168.1.23 i use 192.168.2.15 but you may not have the 2 in yours.

CAN"T SIGN IN TO XBOX LIVE

You might not have been banned. Not being able to connect to the DNS or having it fail can be caused by a few things:
The DNS address serves couldn't be reached
The info on the DNS server couldn't be snagged from your ISP or the DHCP server
The DNS values in the dashboard are wrong.

I don't want to come off like I am insulting your intelligence, but check your internet connection to make sure you have the ability to connect. I'm sure it is all in proper order. So the next thing you need to do is check to see if you IP is set and passes all the tests. If it isn't then you can click the more link on the test page to follow the directions on how to fix it.

You may also want to check out if you are using a XBOX live compatible ISP. Click on Learn More to see if you are using the right ISP or to adjust your settings. You can also check out the connectivity wizard to find out if there are some other issues revolving around this.

Still running into problems!?!?!? try running the modem directly into your XBOX. This has helped me in a few time of need.

Here are some helpful links on what you can do when your DNS fails:
