Having Trouble getting airport to connect to new comcast cable modem

Help, I'm been at this for 2 days now. I don't know why I'm having so much trouble.   I'm trying to transfer from DSL to comcast cable modem and running into lots of problems getting everything to work.
I can't get my airport extrreme to talk to my new comcast cable modem. I've tried everything, restart the modem, restart and reset the airport. chaning out cables, ensuring the green light is at the cable connection of the modem and the airport.
I can find two issues I can't resolve. one, the 10.0.0.1 webpage for the modem/router doesn't response, pings fail to 10.0.0.1. Yet, my computer is talking to the internet nicely using an ethernet cable to this cable modem. I've talked to comcast for hours, to many different people, over Many hours, and they either say the box is working or hang up on me or transfering me to nowhere land.
The airport never goes to a green front light, and airport utility and always dispay an empty IPv4 address. I've tried everything, and can't get the airport to renew it's DHCP license.
Where am I going wrong? I've search the web, and tried the solutions I found. Is my 3 year old airport too old? or is my comcast box bad? I checked the airport firmware and I'm on the latest version.
After getting this working, I still have an OOMA to transfer over to the comcast modem. Am I kidding my self? Help please.

ok, answering my own question, Turns out, there are three ways to do a hard reset on my airport extreme. Only the last method worked. The easy reset, from the Airport utility menu ( clicking the restore default setting) didn't make my airport talk to the new comcast cable modem. The second way, by pressing the reset button while power up didn't work. The harder third way, hold in the reset button and then plugging in the power cord did work. and the airport is now playing nicely with cable modem.   I wasted how many hours before reading this method in the apple support pages ? and then remember doing this trick once many years ago.
I also wasted a few hours trying to get ooma to talk on the new cable modem, and the hard reset key for OOMA to play nicely with a new modem can be complicated. This method requires it to be connected and working ( plug ooma tele into the older DSL network), hook a phone to it, dial * # * # 0 9 9, (star, pound, star,pound then 099) and saying yes.    That reset it to factory settings letting it reconfigure itself to a new modem gateway.
I still can't get into the gateway web page 10.0.0.1 to change the admin password, Don't advertise that. I get no reply to request or to pings. I think some comcast rep changed a port setting so I can't reach it. So I have an open wireless connection and unprotected.
I hate switching my network provider. Now I need to write it all down, for when I get fed up with comcast and decide to move to another provider.

Using airport express to extend Time Warner cable modem wifi signal

I just today got a Time Warner Cable Arris modem with built-in wifi. I'd like to use my 802.11n Airport Express base station to extend the TWC network wifi signal to other parts of my house, but I can't get the Airport Express to shake hands with the TWC modem.
In Airport Utility, under the "Wireless" tab, I've selected "Extend a wireless network". I am able to select my TWC network under "Wireless Network Name." Wireless Security is set to "WPA2 Personal." But when I click "update" the airport express fails to join the TWC network, and my Airport Express signal disappears; I am only able to get the signal back by resetting the Airport Base Station with a paperclip.
Applecare tells me that I might be able to use the Airport Express to extend my TWC network, but they do not support that process. Is there any way to do what I'm trying to do? Are there settings in Airport Utility I need to change? I'd appreciate anyone's help.
Thank you.
Todd

You need TWO Airport units, one to function as the main radio and the other to function as an extender. I used two Express units.
Configuration is simple if you start from a factory default condition. Then connect the main Airport to AC power and finally to the Internet modem (or modem/router). Open Airport Utility on your Mac or other computer and accept all of the recommendations. After confirming that it works, insert your desired administrative and WiFi passwords.
Then connect the extender to AC power. As before, open Airport Express on your Mac or other computer and accept all of the recommendations. No need to add password info.
Do not expect the Airport to respond instantly to the configuration commands. BE PATIENT!

How to extend range of my wireless network with an Airport Express connected by ethernet with Airport Utility 6.0

Hi everyone,
I have AirPort Express 802.11n (1st Gen) firmware 7.6.1, that is connected to my main wifi base station (a TimeCapsule) by ethernet. I would like to extend the range of the Wifi Network but am not clear on how to do so using the new interface of Airport Utlity 6.0.
Does anyone have any tips on how to do this?

Hi Everyone!
Many thanks for the tips. I have downloaded 5.6 and have set my Airport Express in the "Extend a wireless network" mode. I was still having a few problems with the quality of the wifi connection in different parts of my apartment (by no means a very large one, but walls seem to be made of extra dense concrete here in Singapore) and went out and bought a few powerline adapters by TP Link (http://www.tp-link.sg/products/details/?categoryid=1862&model=TL-PA211#spec).
If you don't mind a slightly long post, I would be very grateful for any tips:
My setup is now as follows:
Main room
Time Capsule - connected to a Cisco DPC3925 Modem (http://www.cisco.com/web/consumer/support/modem_DPC3925.html) both connected to a TP Link adapter 1.
iMac - connected via Ethernet to TP Link adapter 2 and wifi enabled
Airport Express 1 - connected by Ethernet to TimeCapsule (and thus TP Link adapter 1) used to stream audio to a stereo that doesn't have an optical cable input. Since it is an Ethernet connection, I have wifi turned off.
Apple TV 1 - connected by Ethernet to TimeCapsule (and thus TP Link adapter 1)
Bedroom A
Airport Express 2 - connected via ethernet to TP Link adapter 3
Bedroom B -
Apple TV 2 - connected by Ethernet to a TP Link adapter 4
After following the tips on setting up the extended wifi network, I find that when I use a wireless client (e.g. iPad, Macbook air, etc) in either Bedroom B or Bedroom C (both don't have wifi in the room) the connection is very poor. Even more odd is that the connection in Bedroom A, one that does have Airport Express 2. To be clear when I mean very poor, I mean Skype/facetime skips frames and freezes... this doesn't happen when I am in the main living area.
I would be very grateful for tips on how to set up the most robust network given the configuration above. Specifically, I am wondering about:
When I select Extend a wireless network option on Airport Utility 5.6 the summary page states that it is connecting using "Wireless Network" vs what I would expect it to say "Ethernet connection".
Is there any advice on whether to enable 5Ghz network and if so, should I try to use that for the various wifi clients?
Does anyone know if I can somehow use Apple products to extend the reach of the Cisco DPC3925? Frustratingly the signal is quite strong (compared to Apple routers), but I cannot properly stream audio/video if that wifi network is used (as my iMac that hosts the content is on the Apple one... and I'd have to walk over to switch it to the Cisco one).
Any other tips would be much appreciated!
Cheers!

Trouble connecting Cisco router with cable modem for Internet purposes

So I am requesting help from the Cisco community on this issue as the cable company states there equipment is working fine. At all my facilities I have a guest Internet service setup through a local Internet provide to provide Internet services to the residents and guests. I have the cable modem usually a Motorola SBG6580 or a SMC 8014 (both provided by cable company) connected to my router on a FE or GE interface. I am using static IPs and using the cable modem just as a modem (bridge mode). Over the past several months these connections have just stopped working. I have not made any drastic changes to my router configs; however, the cable company has updated the firmware on these modems. I am wondering if that could affected how the modem and router talk. I was told by the cable company that the modem sees the Cisco router but that the port is inactive. My router shows the port is active and traffic passing. Does anyone have any ideas that could point where the problem lies? I will post a basic config to one that currently does not work. I am using a VRF to route a certain group out, using NAT. Please let me know if I need to post additional info. Any help would be greatly appreciated.

Unable to connect to internet with cable modem

I have a Imac about 2yrs old. Was running beautifully until lately. My modem shows all solid lights but for some reason it is unable to connect. Did all the things like rebooting, takng out the power cord on my modem letting rest a minutes. Changed the setting to manual from DHCP. Changed it back the other way.
Can someone help me,

Now when you plug your iBook directly into the modem, the internet works. Correct? Which Airport do you have? Try resetting your Airport. Below are some more links that should be useful...

I didn't know what Airport you had, so I included all of them. Select your model and try reseting it. If worse comes to worse, just do a Factory Settings Reset. You will have to configure it like you just took it out of the box. I have found that this usually fixes most AirPort problems.

Can the Airport Express connect wirelessly to a current modem and be the wireless connection for an external??

I'm confused, I purchased the Airport Express and GDrive external hard drive at the Apple store. I already own a wireless modem that works fine (AT&T). I want to extend the wireless signal to the downstairs where the office is and keep the Airport Express in the office (connected wirelessly to the modem upstairs) plugged into the new GDrive to make that wireless. I want the G Drive in the safe location of the office and that was the sole reason I purchased the Airport Express. Is it possible??

As I said, the USB port on the AirPort Express will not support a hard drive. It will only support compatible printers.
If you want to connect a hard drive, you will need an AirPort Extreme.....not an AirPort Express. See this Apple comparison chart to confirm. Might be a good idea to print it out and take it to the "genius" types.
Compare Apple Wi-Fi base stations AirPort Express AirPort Extreme Time Capsule
But, even if you have an AirPort Extreme the chances that it would "extend" the wireless signal from an ATT router are about zero.

Agonisingly Slow Airport Express Connection...

After hours of trying (days actually) i still can't resolve this, so hopefully someone out there can. Running an iBook G4 with Airport Express hooked up to a cable modem, the connection speed - at best - is about 10 kbps, and is usually worse than a dial-up. If the computer is hooked up directly to the modem, speed is as it should be - about 190kbps - so the problem is not the ISP or the modem. Testing on a friendly neighbour's wireless network, my iBook also hits those speeds - so the prob is not with my iBook.
I have tried changing channels and inference robustness in case of interference. The firmware is 6.3 and Airport software is up to date. I have hard reset the Airport but still no joy.
My question is, is there a perhaps a software or a permissions conflict or something that be slowing this down? Is there a way of taking the iBook back to a time before it knew of wireless, and trying to install everything again? Is it possible the Airport is just broken?
If anyone could help i would be extremely, and expressly, grateful.

Hello all,
Well the Airport has worked in the past, and now it is working again, after lengthy calls to customer service. What happened is this. Instead of just unplugging the modem for a few minutes to try and reset things, I read on these forums that to solve a potential MAC problem (i don't know what that is, but apparently it can affect cable modems and conenction speed) you need the modem unplugged for half and hour or more. So i unplugged it from the electricity overnight. When i plugged it back in, it seemed to die. All the LEDs came back on and stayed on without blinking, like it had frozen. The cable customer service tested it from their end and said it had died. But as the cable guy was coming over to fix it, it unfroze (after maybe an hour of being frozen) and hooked up to the airport at top speeds again.
So, two conclusions.
ONE - Dodgy modem, not dodgy airport.
TWO - If you have a speed problem with a cable modem, you might need to unplug everything for a while, not just a few minutes.
I hope this helps. Thanks to everyone for the advice. These pages remind me why i have a Mac, which after screaming at my airport (unjustly as it turns out) i had almost forgotten.
Cheers,
Bedevere

IMac Model 10,1 cannot connect to Internet, either with cable modem of Airport. Solutions?

iMac 10,1 cannot connect to internet via cable modem or Airport plugged into cable modem. MacBook Pro, iPad and iPod are fine. Reinstalled OS10.6.3with no results. Ideas on where to go next welcome.

How do I set up Airport Extreme with cable modem and router?

Hi--
I'm having a house built and all of the wiring for TV, phone, and internet will be centralized in a closet. The cable modem can be placed there as well. In one room in the basement I want to use my Airport Extreme for my iMac and USB external hard drives. In another location of the basement, I'd like to set up a Time Capsule for another desktop and USB printer. If the cat5e comes out of the wall at each location, I "think" I need a router at the closet location. I also thought I might need an Airport Express upstairs on first or second floor to boost signal for my laptop. The house isn't that big so maybe that's overkill. So beyond the router question, do I want to set up a roaming network and have the Airport Express connected via ethernet or just wireless if the thought is that I need this? Finally, if I should connect cable modem to router to Airport Extreme, Time Capsule, etc., in what order and ports does the equipment get connected? Many thanks!!

Welcome to the discussions, Forum Girl!
It would be best to position the cable modem and main router in the central location like the closet if possible. The other devices would connect via ethernet to the wall jacks in each room.
If you could setup a "roaming" wireless network as you mention, this will give you better wireless performance and coverage. This is the way commercial establishments like airports, businesses, etc. are configured for wireless.
The order of connection would go something like this: ethernet connection > cable modem >main router>devices. Devices could be computers, routers, a backup device, etc. Since the Extreme has only 3 LAN ports for ethernet connections, you will also need to plan to install an "ethernet switch" near the location of the main router to provide enough ethernet jacks. If you are planning to use DirectTV, etc or your audio/video devices require ethernet connections (most new products do for updates and extra features), be sure to plan for that as well.
Make sure that CAT5e or CAT6 wiring is run so you will be able to take advantage of faster gigabit speeds.
Finally, it would be a good idea to work with an IT specialist to go over your plans to make sure all the bases are covered. This would be money well spent.

Time Capsule connectivity issues with cable modem

I have Comcast internet service (coming through a Linksys CM100 modem, no router) plugged directly to a 2TB dual-band TimeCapsule. In the past this has been working, and the TimeCapsule has been providing internet access to three Macs, as well as backing them up. I also have an AirPort Extreme base station (not the dual-band one but not the 2003-era UFO-shaped one either) that has been connected to the TimeCapsule over house ethernet to provide wireless through the rest of the house. Last night my connection kept dropping out. I could connect to one wifi network and it would not work, then I would connect to the other and it would work for a while before stopping. I have disconnected everything and then replugged only the cable modem and my TimeCapsule. When ethernet is plugged directly into my iMac from the modem, I get an internet connection without issue. When I plug it into the TimeCapsule, it reports an internet connectivity error. It says it gets no IP address, and no DHCP setting that I provide it with alleviates this message.
I'd be gratful for any suggestions on how to fix this issue. I don't really want to wipe the TimeCapsule completely, as it contains our backups to last July.

When ethernet is plugged directly into my iMac from the modem, I get an internet connection without issue. When I plug it into the TimeCapsule, it reports an internet connectivity error.
Because cable modems associate and "remember" the device with which they have established a connection, they need a complete reset whenever you change the device that is immediately connected to them.
Push the reset button, If present, on your modem
Power off the modem
Pull the battery if it is easily accessible
Power off everything else on the network, order if not important
Wait at least 15 minutes
Make sure that the Ethernet cable from the modem is connected to the WAN port (circle of dots icon) on the Time Capsule
Power up the modem and let it run 2-3 minutes by itself
Power up the Time Capsule the same way
Power up each of your other devices about a minute apart
Check for proper operation the network.

Set up Airport Extreme with 2 Airport Express connected by CAT5??

I recently bought an Airport Extreme base station and an Airport Express. My plan was to use to Airtunes with my AV receiver in my basement. Unfortunately, because the distance between these two areas is long (and separated by two floors) I'm not able to get a strong enough signal with the Airport Express to use Airtunes. I bought another Airport Express to put on the middle floor of our house but the signal in the basement was still not strong enough even with this addition.
I do have a way of connecting the middle floor of our house with the basement area by a CAT5 ethernet cable. My plan now is to connect the two Airport Express modules by their ethernet ports with this cable. The Airport Express on the middle floor connects with the Airport Extreme base station wirelessly without any problems. My question is what is the proper setup for the 2nd Airport Express connected by ethernet in my basement.
Airport Tech support said this could be done. They recommended setting up a new wireless network with the 2nd Airport Express by "fooling" into thinking it was connected directly to the router but using the same network name with a different wireless channel as my Airport Extreme base station. This setup actually works for several hours but then the Airport Express module that is connected to the Airport Extreme blinks amber. Interestingly the 2nd Airport Express with usually remain with the green light on.
Does anyone have any suggestions for the best way to set this up regarding network configuration with the Airport Utility?
Thanks

That will work with as long as the AirPort Express (AX) is connected via Ethernet. The only other setting you need to make is to configure it to act as a bridge (not sharing a single IP address).
If this one looses connection, then something is wrong with the AX or the Ethernet connection (cable and/or connectors).

Airport express connect with Imac via lan line or can not?

I using IMac with connect to internet with DSL modem router (having 4 lan ports).
Now I put Airport express connect with one of Lan ports from DSL router and still connect my IMac with DSL router via lan line and still connect to internet via lan line (switch off airport function in Imac).
The Airport express is using for provide wireless internet and printer to my other PC.
My Question is can I still set up as above and connect share file to my PC via airport express?
Forget to tell that I'm very newby to mac.

chounws, Welcome to the discussion area!
Yes you can do that. Configure the AirPort Express (AX) to operate in bridge mode (not sharing a single IP address).

Time Capsule with (2) AirPort Express connection problem

I have (1) Airport Time Capsule with (1) AirPort Express connected. I'm trying to connect another Airport Express but only get a yellow light on the 2nd Express. If I connect it with a ethernet cable I get a green light. How do I connect a 2nd Express?

The 2nd Express needs to be about the same distance from the Time Capsule as the 1st Express....and....it cannot be closer to the 2nd Express than it is to the Time Capsule.
The reason for this is that the Express will pick up the strongest signal and you want the Express to pick up the Time Capsule signal to be able to extend it.
Then, start over as LaPastenague instructs on the 2nd Express and configure it again.

Using Airport Extreme Base Station with Cable Modem

Hi everyone,
I have just bought an Airport Extreme Base Station. I connected it to my cable modem (Surfboard 3100) through the WAN port and my iMac G4 is connected to it through the Ethernet port. Installed the Airport Utility, and configured the base station with the normal settings of DHCP for Internet and DHCP for internal network.
After restarting the base station, my Internet connection from the iMac through the base station is very slow and most of the time will time-out. My Internet connection through my PowerBook G4 using wireless through the base station is ok though.
My question is, is there some setting which I should set for the Ethernet portion of the base station to make my wired connections to the Internet work?
Thanks in advance for any help!
regards,
Weiming

Hi,
My iMac G4 does not have an Airport card. I did not physically restarted the base station, its part of the sequence when we update the configuration, that the base station will restart on its own.
regards,
Weiming
