Question about Linksys Wireless-G WRT54G Router

Connectivity with my comcast cable

Late Dec of' '08 we got Comcast cable, multiple users, wireless, we declined to to use their router and their man and others recommended the Cisco Linksys ''G'' model. Comcast has come out and basically have said it's the router/Cisco problem. Cisco says it's Comcast. We replaced it with the another new Cisco Linksys ''G'' model and same results. What happens is we will have decent use as long as a few days, usually hours to overnight. Then I have to play the game. Unhook the modem, and router, plug back in, press the router button until it flashes green. It won't stay green. The modem lights are all green except the link light which flashes green. We also have phone and cable for tv. We do leave the computer running, signoff everything and turn off the monitor.

I have the same modem and comcast cable as the ISP. We had a similar problem and it turned out to be the level of the signal coming from the street drop point. The first level techs had no clue but when a more senior tech came out he measure the level and reduced it. Might have them check this out.

I have a comcast for 10 years with a cable modem and tv. The only time I ever had problems and they were major, they needed to run a new line, that's the only thing that stoped the signal from droping.Previous to that, there was an inline amp on the line, and that would have intermittent isues that you describe. Another reason may be the modem, it may be the "old" unit, tell them you need a new modem. They are going to give you a hard time because you aren't using their modem, so every time you call, they are going to ask you to disconnect the router and run through the modem.They can read the modem from their side, and if it is "on", they will stop right there. You are speaking to someone who is out of the country. I made the mistake one day of asking them if there was construction going on in my area, "because they daisy chain" the connection, and if the house next to you has the cable pulled out, it can effect you. The woman told me "she didn't see anything" so I asked her where she was because the homes on both sides werer having work done, She was in India, they outsource to Canada and India so it would be difficult to see if there was construction in Fl.They are only going to react to things that they are authorised to fix. Call them and tell them that your modem goes on and off, forget the router for now, ask for the motorola 8500 series. You may have to ask for a supervisor and don't let them talk you out of it. You also should tell them that your intermittent issue happens wheather the router is on or off, since they don't understand unless they walk you through the basic troubleshooting, which is a waste of time. You are loosing your signal because the modem is droping the connection, you can also look on the Linksys home page, and see if there is a firmware upgrade for your router, but make sure you get the right version number of the bottom.The last thing to check is to see if they have "filters" on your line, they can also cause problems with the modem. If you have a private home or condo, there is a box that stands out someware on the lawn or off to the side. Usually its not locked. Pull off the top and see if you see silver cylindrical looking tubes about 3 inches long inline with your cable line going into the box. If so they may be causing the problem. I had 3 of their trucks on my lawn at one time, and they couldn't figure out what was wrong. ten minutes after they left I had everything running. The problem is subcontractors, are doing the work and you either get a good one or a bad one, you need to keep having them come out until they get it right. So just to go over it again, Modem, Firmware on router, Wiring coming in, Filters on the line. Get to a supervisor right away or you will have to tell the story several times. Also if they do come out, ask him what his meter is telling him your signal strength is. Cable is shared and if others are using their service at high load times, that is another reason that your connection must be perfect, or this is going to be ongoing. good luck

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.

Will comcast support Actiontec - ADSL Modem with 802.11g Wireless Router and 4-Port Ethernet Switch


Comcast will not support that kind of modem. Comcast is a Cable ISP thus the ADSL modem won't work with them because ADSL modem is for DSL providers. Cable Company uses different protocol than DSL. But Comcast will provide you the cable modem if you subscribe to them.

Wireless router isn't getting internet connection


I am running DSL, but I am sure the method would be the same. The BNC connection (cable) should first enter the cable modem, then ethernet from the modem to the wireless router.

Belkin G wireless Router


Do you have an all-in-one router from Comcast? For example, do you have the cable (RF) line and your PC plugged into the Comcast router? If so, unplug your PC from the Comcast router and connect the Internet port of the Belkin to the ethernet port on the Comcast router. Then plug your PC into the LAN port on your Belkin.

[PC] ---> [Belkin] ---> [Comcast] ---> Internet

Once you have connected your boxes as displayed above, you will need to power everything off and bring up the boxes in the following order:

Comcast (wait 60 seconds)
Belkin (wait 60 seconds)
PC

If you cannot get out to the internet, momentarily press the reset button on the back of the Comcast box. Comcast routers are weird. A poweroff should reset the router but I have seen a few times where nothing works until the reset button is pressed (this is also recommended by Comcast).

I hope this helps.

Arimex comcast router won't talk to belkin wireless g plus mimo router


Comcast has a little known "trick" that they use when setting up users. Here's how it works:

When Comcast first comes to setup your new cable modem service, they insist on connecting it to your computer and "testing" it. Most people think nothing of it, and that it's good customer service ...truth be told, what they are doing is attaching your computer's MAC address to that cable modem, so that you cannot create a wireless network. This is because they want you to pay them $150 to do this for you.

In this situation, since the modem is a modem/wireless router in one, my guess is that the MAC address on your machine now does not match the MAC address on the new router, which is what Comcast has stored in their database(s).

Try this: on your computer (while connected to the modem), perform a release on your IP address (start, run, cmd, then type "ipconfig /release"). Disconnect the ethernet cable from the computer. Turn computer off completely. Hold down the reset button on the cable modem until it performs a reset. Once it's back up and running, boot up your computer with the cable back in the ethernet port.

The cable modem should assign a new address to your computer. However, that may or may not work ...this is an easy workaround with a Linksys router, but not necessarily with the all-in-one devices.

Worst case scenario: contact Comcast and notify them that the new modem is not recognizing your computer's MAC address and that it needs to be updated in their system. They will scan your computer (through the telnet interface on your modem) and get your computer's MAC address, then (hopefully) make the necessary changes on their end.

After that, everything should work flawlessly. If not, insist on a Comcast tech to "fix" the service that you are paying for.

Good luck - hope this helps :)

Other computer won't connect wirelessly


Comcast is apparently weeding out multiple connections through routers. They want you to pay extra for their wireless router and pay an extra $5 a month too.
