I HAVE A NEW HP DESKTOP AND AN OLD LINKSSY WIRELESS G


Hi Vivian,

Chweck you cables and where they are conencted.

You will need to make sure that the Comcast modem is providing internet, you can do this by connecting your laptop to it using ethernet directly if it connects to the internet, that will be a good thing.

From your comcast Modem, the ethernet Cable should go to the linksys where it says "WAN". this should give you an internet connection and make your comcast modem communicate with your linksys Router.

D-link has stopped working with comcast internet.


Are you trying to install the router.You can do it manually
without the CD.
MAke sure that your computer is able to go
online through the modem.
If your computer is able to go online
through the modem
Then you need to connect the computer to the
router ad the modem to the router.
open the set up page of the
router and change the settings of the router according to the
ISP.

Moved router to connect directly to the Comcast modem that also provides VOIP. Comcast activated modem and internet works when computer is connected directly to Comcast modem. Router does not connect to...


Your ISP should have given you the following information...
Static IP, Internet IP Address, Subnet Mask, Gateway, Static DNS 1-3.
With that information at hand, follow tis link to the router user manual and go to Page 11 of the manual to go through the step by step process of setting the router up for an internet connection.

No more internet thru router after new modem installed


Router setup
Go to the control panel and un-install the program that the Comcast cd installed. then:
Shutdown your PC. Unplug the power from the router and the cable modem.
Wait 30 sec. then plug in the power to the cable modem, wait 30 sec. then plug the power to the router. Wait till you have "Internet" light then restart your PC. The PC should pick up an IP address and you should be able to get on-line.

Did Comcast reset you wireless router settings? If so, you may need to set up your SSID and security settings.


Customizing Wireless Settings of the Router
Having default wireless settings on the Linksys router may cause conflict with other Linksys routers within your network range. Linksys suggests changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.
To change the router’s SSID or the wireless network’s name, click here.
To change the router’s channel, click here.
To enable the wireless security on the router, click here.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Linksys wrt160N router inconsistant internet connection


Check on your cables makes sure they are inserted properly and the cord should be free of kinks, scrapes or loose connections......Also check the back of your computer make sure your ethernet card (the one that has the green lights/LED's) is seated properly (not loose)....

Good Luck.....hope this helps...if not let us know....cheers

PS3: i can obtain ip adress but fail to connect to internet.


I would suggest that first you stop using the first modem. Then plug your computer into the modem and install using the comcast cd that came with your welcome package. If that doesn't work please tell me.

I cannot connect with linksys wireless router


From your description, you appear to be connected to the router fine.

Try powering down the modem from Comcast for about 2 minutes then power it back up. If it doesn't come back, call Comcast service as it is likely on their end.

Hope this helps.

Why does this keep happening??? Please advise...


Your modem is set to only allow one main IP address, which it assigned to your laptop.

Connect the cables through the router, then unplug first the modem, then the router.

Wait 45 seconds, then plug in router, wait 5 seconds, then plug in modem.

Give it a few seconds to talk to everything, and you should be good to go.

Please help...internet won't connect


You may be running into a problem of your ISP only allowing one computer on the internet. while the internet is on can you access the internet from the desktop comcast originally setup?  If so that is more then likely your problem.

I have comcast myself and they told me they do not allow home networks. I fixed that problem by using the mac address cloning feature in my router.

The setup cd is also junk, all you should really need to do is:
1. unplug modem, router, and turn off computers
2. Plug modem into router
3. Plug computers into router (don't worry about wireless right now)
4. Turn on modem, wait 20 seconds or so for lights to set,
5. Turn on router. again wait for lights to set
6. Turn on ONE computer that is hard wired into the router
7 Try to surf the net.
8. If successfull try to connect wireless computers (Without using cd) and see if they surf.

If not call comcast and see if your computers are trying to obtain real-world ip's instead of LAN ip's like they should.
If so, you'll need to enable DHCP on the router.
