WRT54G connect to Comcast cable - SUCCESS

There are so many of us asking for help to get WRT54Gs to connect to the internet, I thought I'd post a success notice.
Mine is a V5. It has progressed from simple connecting to encrypted connecting, and has been running several days at each.
What seems to have made the difference was:
1. Update the firmware to the latest level, and
2. Change the LAN address from 192.168.1.1 to 192.168.2.1.
Since doingthe above I have seen no need to clone the MAC address of any pc (even though I'm dealing w/ Comcast and that seems to be a "default" suggestion when Comcast is mentioned). I've connected using both LAN cable and wirelessly from a Vista pc w/ built-in, XP pc with built-in, and XP pc with PCMCIA card (all G-types)
Initially I just did unsecured to see if it would work for a few days. I had never gotten more than about 2 days life out of any setup prior to this. After that, I secured it, and it's still running fine.
Thanks to Linksys Tech Support. I had already done the firmware upgrade on my own, but the suggestion of changing the address came from you. Quite frankly, I got that suggestion a few weeks back before the firmware upgrade, and it didn't seem to be as successful then. I think BOTH are needed.

When I looked at Status, I had a Comcast IP. I changed it to 2.1 because you Tech Support told me to. You gave me a pretty good explaination of why it might be important to do that, and the only thing didn't jive was that Comcast didn't SEEM to be presenting me with 192.168.1.1. However, since it works and since I have a policy of not fighting success, I simply moved on.
I currently have 98.196.142.30 coming in. Not sure if that has been the same all of this time or if it's been re-assigned at some point. Since I've had no power fluctuations I'm inclined to think it's been the same.

i have a Linksys Wrt54gs connected to a Cable modem.
it worked for about 8 months.
My kid pressed a button by accident and now it won't work.
the router just keeps resetting.
i unplugged everything.
conencted 1 computer, and everything is fine.
Received DHCP address.
Once i plug in a second computer it starts rebooting.
Both computers are set to DHCP.
NO internet connection is connected at this time for troubleshooting purposes.
Nothing is connected to the ethernet port on the Linksys router (port for internet access), only 1 and 2 are connected.
i reset the router and still nothing.
i can connect 1 computer via wireless and 1 computer via direct connection and all is good. Once 2 devices are connected via direct connections it starts resetting.
i can even connect the modem to the router (for internet access), and connect to the linksys router via wireless from my computer and get internet access.
But once i direct connect 2 connections, the router starts resetting.
i have reset and reboot it with every combination i can think of.

Its good that its working now.
If it happens again, try this :
Press the reset button on the router for 30 seconds. The Power light will start flashing. Turn the Router and the Modem OFF. Turn the modem ON first, wait for 10 seconds, turn the router ON, wait for 10 seconds, you should be ONLINE !!!
Do this when the computer os connected to the router with a cable.
than on the computer open Internet Explorer and in the Address Bar type : 192.168.1.1 and hit enter.
It'll ask for the password. The default password is admin.
Once in the setup page. Click on the Wireless tab.
In there Change the Network Mode to mixed. And change the SSID to your name.
Change the Channel to 11. And Enable the SSID Broadcast.
Save the settings here. After that Click on Wireless Security and configure it accordingly and Save the settrings.
Than click on Advanced Wireless Settings. In there Disable the SES function.
What is the firmware on the router ?

Internet Dial-up connect without Comcast cable ?

What hardware/accessories are needed to establish an internet connection via HiSpeed dialup service
Want to use Copper.net(eg) and quit paying for & using Comcast DSL modem(they are a monopoly here in Jersey City,charging $50/month) ???
Is this even possible ? I have only this one computer & no network.

King H.:
Welcome to Apple Discussions.
To use a dial up connection go to Apple menu > System Preferences > Network > Show > Internal Modem and set up account information. To do your regular dialing up you can to to Applications > Internet Connect. Select Show modem status in menu bar and connect either from Internet Connect or clicking the phone on the menu bar and selecting Connect.
To get more info on this you can call Tech Support and the ISP and they will guide your through the process. You can also, while you have System Preferences open, go to the Help menu, launch the Help Viewer and browse for the topic you need.
Please post back with any specific questions on this subject.
Good luck.

WRT54G connection issues with cable

My router was working fine after few months back, 1 thing I suspect is that I upgraded to the latest firmware of v.2.
The problem is the access to the out world stops working, I can login into the router wireless and access all the UI but if I PING from inside the router to an external site it just doesn't work.
The only way to fix this is by resetting to the default settings (in the administration tab) or hard reset (power button from the back), after this it works but I need to configure again the security, after a while may be a day or some times 4 days after it stops working again and I need to repeat the same steps.
What I believe is that for some reason something gets renewed in the router and messes up with the routing table so nothing can go outside the router itself.
I called Linksys and they didn't help is there somebody with the same issue ? How can I fix it?

HELP I have a wireless Linksys router WRT54G connected th...

HELP I have a wireless Linksys router WRT54G connected through my cable company broadband modem on a Mac. I have another computer to which I installed wireless capability because it didn't come with it. This required attching some piece of equipment to the back of the PC which enabled it to get on the internet without another cable modem. My question is this. If I get an iphone or a laptop(with built in wireless ability) will I automatically be able to go on the web because of the router on the Mac.

yes certainly... if you get any wireless device in network that would certainly connects to a wireless n/w of router...

WRT54g connected to modem with router

Got a WRT54g connected to a cable modem which acts as a router. The WRT54g gets an IP address (192.168.1.x) from the cable modem and the WRT54g can ping and tracert to sites on the internet (from the diagnostics page). The WRT54g is acting as a DHCP server for the 192.168.9.x network and I have the cable modem connected to the WAN port. (I need to have the cable modem connected to the WAN port b/c I'm using all the ports of the WRT54g. I want to have the cable modem connected to the wan port too so the network are separate subnets).
Any idea why packets would not be going through the WRT54g? I've tried setting the router and gateway modes, neither of which work anymore. I think I used to have it set to router and it work.
Any thoughts? Suggestions?
Thanks in Advance.

What network is 192.168.9.x...What other router router you have apart from wrt54g?What is the model number of the other router?What is the exact physical connection between the modem and the routers?

Cannot conncect PC to internet through wrt54g version 5 (I have Comcast cable internet)

I had my Comcast cable internet installed yesterday and tried to connect my Linksys wrt54g V-5 wireless internet with no success. I have tried running through the CD install setup multiple times (even doing the 30 sec power cycle) and at the end of the program Im told "PC cannot connect to internet". I've also tried switching around different cables and still nothing...
Just to be sure I've done the power cycle correct, these are the steps that I took:
1) Unplug internet cable from PC>router>Modem
2) Unplug router battery (after holding reset button for over 30s) then Modem.
3) Reconnect Modem cable to Router internet port
4) Reconnect power to Modem
5) Connect cable in port 1, 2, 3 or 4 (tried them all) to PC
6) Reconnect power to Router (waited for a few min)
7) Turned on PC and tried the Install program again with no success
I believe I have to clone my MAC # for the router from my PC but I cant connect to internet with the cables attached (or wirelessly) to the modem and the router, but I can get on the internet directly from the moden just fine, and the Linksys shows green across the board when everything is connected...
Is there any other way to clone the MAC # with out having the Linksys attached or would that be self defeating??
Any help would be MUCH appriciated (especially b/c the Comcast folks want to charge us AGAIN to come back out and install the wireless when I specifically asked to have it done the first time...)

Do not use CD to configure the router..You can configure the router manually.
Open the set up page of the router by launching an Internet Explorer Browser and type the address bar, 192.168.1.1 and press enter. When it prompts for the username and password, leave the username field empty and provide password as admin and click on ok.
On the main setup page the ""Internet Connection Type"" should be on ""Obtain IP Automatically - DHCP “. Click on the Save Settings button.Now click on the sub tab ""MAC address clone"".Click on enable..Click Clone & click save settings ...Check WAN Ip on Status page of router .... If getting Valid IP,try going onlineIf not ... power cycle for 4-5 minutes & then again check the WAN Ip address .....

I will be using a HDMI cable to connect an Apple TV box and a Comcast cable TV box to my TV. My TV has only one HDMI port.

I will be using a HDMI cable to connect an Apple TV box and a Comcast cable TV box to my TV. My TV has only one HDMI port.
To do this I will need a 2x1 HDMI splitter or a 2x1 HDMI auto switch (preferred).
?Is there any Apple TV HDMI port voltage?
When using a HDMI auto switch to connect two devices to a HDMI TV, the
Auto switch cable box only works for components that do not output continuous voltage over HDMI port when turned off.
Do you know of any other solutions? Componets? Actual expierances?

Cable : HDMI switches expand the number of available HDMI ports on a high definition television allowing connection of cable boxes, Blu-ray players, and game consoles. A side benefit is that cable clutter is also eliminated by running a single HDMI cable to your HDTV from a switch and relocating the HDMI ports to a concealed location. The problem with most HDMI switches is that you have to either get up to push a button, or hunt for the remote control, to switch sources. The true mark of any great switching component is an ability to perform its function and remain transparent in its operation. This automatic HDMI switch is a plug-and-play away from offering everything you are looking for in an HDMI switch. Select a single output from up to three devices for signal delivery to your HDTV. Smart operation provides complete control for connect-and-forget operation. Powering on a device gives it output priority over the other devices. By powering down the device in use, output priority is returned to the last powered on device. Note: Auto switch function only works for components that do not output continuous voltage over HDMI port when turned off.

Hi Erico,
I tried what you said again but without success. I even updated the driver so that that audio driver is the same as the graphics driver i.e.. NVIDIA but this has not helped either:
Do you have any other ideas?
Many many thanks,

Comcast Cable Internet not working with router (WRT54G), but network is fine?

My Comcast Cable Internet is not working with my router (WRT54G), but my home network is fine. The internet works without router.
I have a WRT54G Wireless-G Broadband Router from Linksys.
I was using Bellsouth DSL Internet up until two weeks ago.
I had my DSL modem connected to my router, and the router let me use the internet and share some files and printers with my laptop upstairs.
A few weeks ago we changed to Comcast cable. The technician came in and connected it himself, but only for the desktop. The internet worked perfectly, and still works perfectly on my desktop (the one downstairs). He didn't really give me any instruction or CD-roms for it.
When I tried connecting my router, the internet stopped working. It was weird because the router worked for the file sharing and printer sharing between both my computers, but the internet didn't work. Although, the light for the internet is lit on the router itself.
I even have this program called "AOL Network Magic" which shows a map of what is connected to the router, and it shows that the router and my laptop and desktop are connected, but then it has an "X" for the internet connection.
I have tried everything. I lost all of my CDs and things that came with Linksys, but I downloaded some guides from the Linksys website and it doesn't really help. I tried something called "NetSet", but after I set everything up it says my router is not compatible or something with NetSet. I read a bunch of FAQs, I tried going to comcast and seeing if they had any FAQS about it, but I can't find anything.
Maybe one of you can help me?
Also, I don't know my modem's IP address. I had it for Bellsouth, and sometimes when I would lose my connection I would go there and click on "reconnect" or something like that.
So the only way I can use the internet is to disconnect everything from my router and connect the ethernet cable directly to the modem.

You may open the web setup utility page of the router by typing its IP address on your browser's address bar. By default, it is 192.168.1.1. When you're asked for username, you may leave it blank. For password, its "admin". If in case that does not work, reset your router at the back for 30 secs and do a power cycle again, see if it becomes accessible after that...

EzVPN issues with a Comcast cable connection

I have a problem with a Comcast cable connection and an EzVPN. Simply put the connection drops within minutes of no activity. In other words, if I leave an RDP connection open from my datacenter to the remote site, the VPN connection will stay open all the time. A few minutes after I close the connection the VPN drops and the remote side has to wait until its keys timeout to reconnect (obviously without a reset).
I have multiple sites connecting to the EzVPN server without issues from multiple carriers. This one Comcast connection seems to be an issue. I've verified that the configurations for other DHCP based cable connections and this one are the same (except for local parameters). I've also run PING tests to test reliability and MTU issues. For the reliability I do have 1 - 2 packets out of 200 consistently dropping with a 2 second timeout value for the PING. (This is pinging the next hop router on the connection.) For MTU I was able to PING with packet sizes all the way up to 1500 bytes with the DF bit set.
So, I'm looking for any direction on this issue.

[WRT54G] What type of cable to connect router to cable-modem?

Hi,
What type of cable do I have to use to connect a WRT54G router to a cable-modem, straight UTP or cross UTP?

Normally you would use the standard (straight through) ethernet patch cable.

Can access internet when connected w/ethernet cables in router, but WRT54G says it can't connect

I have my router, modem, and computer all set up correctly. I can access the internet in this setup but with only the computer that is connected with the ethernet cord to the router. Yet, my WRT54G router can't connect to the internet in the Linksys easy setup nor through the http:192.168.1.1 method.
When I changed the internet connection type to PPPoE, my modem was unable to access the internet. I also changed the IP to 192.168.2.1 but that didn't help. I have performed several power cycles. I have upgraded the firmware.
I changed the internet connection type back to DHCP, so I am able to come on this website, but I can't set up the wireless since the router says it can't connect to the internet. Please help!

Start it from scratch...Reset your router and re-configure it...
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
Also make sure that your computer is set to obtain IP automatically, disable any firewalls, security softwares on the computer before trying to access the setup page.
If your Internet Service Providor is Cable follow this
If your Internet Service Providor is DSL follow this

Now see if you can locate your wireless network on your wireless computer and attempt to connect...

IBook and Comcast Cable modem--can't connect to Internet? Please help

Hello everyone!
I have an ancient iBook . Here are the stats:Mac OSX version 10.0.3(told you it was ancient), 193MB, PowerPC G3. I bought it off of eBay about two in half years ago and it didn't come with an Airport card...I only received a laptop, the original box, some cds, and the adapter. I have a Comcast cable modem and I was wondering if anyone could help me figure out how to connect my iBook with the modem. Prior to Comcast, I had Bellsouth and all I had to do was simply unplug one end from my mother's Dell and plug it into my iBook and it instantly connected. However, I can't do it with the Comcast. Can anyone tell me how? Pretty please?
iBook Mac OS X (10.0.x) PowerPC G3, 193MB

You likely need to contact Comcast to get them to help you set up the iBook for your new cable internet service. They should be able to walk you through it.
In case it may be an encryption problem, you may want to check out iFelix's post in this thread:

Connecting Apple TV to Comcast Cable...

I have a new Apple TV and also have comcast cable...also a oder bose lifestyle system (I know its not great sound). When we connect Apple TV to the HDTV via HDMI I no longer have sound out of the lifstyle system since it is connect to the cable box...Can we connect Apple TV to the Cable Box? Or does the bose system need to be connect to the TV so it works with both?..thks

The Apple TV also has an optical audio out. If the Bose has that kind of input you can connect to it and leave the cable box alone. If the Bose system does not have digital inputs, you can connect cable and ATV2 using HDMI to the TV and then connect the Bose to the TV audio out....

WRT54G V5 loses connection to BEFCMU10 cable modem

I have a BEFCMU10 on my cable internet service, with a WRT54G downstream. The cable modem works fine, and when the computer is connected directly to it, all is well.
When I connect the WRT54G, all is fine for, say, 8 hours, then the computer loses the connection. Cycling the power to the WRT is required to get up and running again.
I suspect that I have not configured the WRT correctly. It's set to use DHCP to connect to the BEFCMU. Are there specific settings I need to make for this setup?Message Edited by stowaway on 08-21-2006 05:05 PM

If you connect your computer directly to the modem, are you able to go online without any problem? If yes, try to access the setup page of the router and check the status page of the router and check if your getting a public IP address under internet IP. If your not getting a public IP, go to the setup tab and click on mac address clone, enable the mac clone and click clone pc's mac then save the settings. after that do a power cycle on the router and the modem and try to check again the status page of the router if your getting a public ip. If your getting a public ip and still having the same problem, try to lower down the MTU of the router to 1490 up to 1300.
