AX + PC + MacBook + Cable Modem = Problems

Hey...
So after reading all the comments on the Airport Express product page about "ten minute installs" I thought to myself "Ten minutes to install an Apple product? What were you doing, making sandwiches at the same time?"
Two hours later, I can't get my AX working properly. Great.
My setup:
Desktop PC running WindowsXP to Motorola SB4200 cable modem --> Ethernet cable from modem to Airport Express --> MacBook with 10.4.9 connecting to Airport Express for wireless internet.
I'm not at all trying to use AirTunes...
At any rate, I got things up and running last night just by plugging things in and running the setup assistant. Solid green light, strong signal, almost instantaneous web surfing.
Then I noticed I couldn't send emails on the MacBook -- could receive them, no problem, but could not send them.
Shortly after, I also noticed that the internet connection on my desktop PC went dead. This is while I'm simultaneously surfing with the MacBook with no issues, so I know the modem is working fine, but somewhere there's an issue with how the two, my MacBook and PC, are sharing the cable modem and I couldn't begin to guess how to solve it.
However, in my attempts to remedy the issues, I did:
1) Reboot both Mac and PC
2) Disconnect power from the cable modem briefly, then reconnect it
3) "Reboot" the cable modem, using the blue button ontop
4) Remove network security on the AX
5) Hard reset the AX unit
Any help would be greatly appreciated -- thanks!

OK. So I called up my ISP and they let me know something that didn't seem intuitive: I can't have both ethernet and USB connected to this cablemodem without instead a proper router dividing tasks up. The SMTP problems seem like they could be solved once I get a proper router sorted out.

WRT54G2 w/ cable modem problems

After configuring a cable modem (motorola) with the
router everything worked perfectly. (I used the MAC clone setting, DHCP.) My friend rebooted the wireless laptop with Vista several times and the internet worked perfectly.
That night, when she went to use the internet, it didn't work. Power cycling resolved the issue. A few hours later, same problem, power cycling resolved. The next day, even power cycling didn't resolve the issue. Any thoughts?
How can I fix this problem? Any ideas? How can I resolve power cycling issues, and is there a more advanced setting I can change?

If you have to power cycle your wireless router continuously then you should upgrade your router's firmware...
Download the Firmware from here
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say Page cannot be displayed".
Now reset your router :
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...
If your Internet Service Providor is Cable follow this link
If your Internet Service Providor is DSL follow this link
Adjust Wireless Settings -
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave username blank & in password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Wireless channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bit.Leave the passphrase blank, don't type in anything...
Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...
Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...
If you keep loosing the wireless signals, then you should download and upgdate the drivers for your wireless adapter...

UK User with Cable Modem Problem

Hi all
I have just signed up with VirginMedia for TV and Broadband. Access to the internet is offered rebranded Ambit U10C018 Data Cable Modem. I have a Mac BookPro 2.33GHz and a Airport Extreme 802.11n base station (firmware v7.2.1) providing my wireless network.
Wired access to the internet (i.e. connecting my MBP to the cable modem via an ethernet cable) is fine.
The problem I have is when I surf the web wirelessly. Requested web pages are taking a long time (15-30 seconds to load); pages which load instantly via a wired connection. I have used the AirPort Utility to try various different settings but they have not made any difference. The VirginMedia engineer who came to my house has suggested that there is an incompatibility between the AEBS and the cable modem.
The Ping and Traceroute output below look normal. NsLookup returns quickly, so I don't think there is a DNS problem.
My question is whether anyone else has had any similar experiences? What advice can you give me here? Should I look at getting another wireless base station?
many thanks
Nigel

I wonder if my problem was solved which seems similar to yours. I have just brought a preused G3 , 400, running Panther. I want to use this as an backup to my DLS G4. It all seems oka and does everything it should do, but it seems unable to make a connection with any ISP. You can hear the modem dial out, but it fails to trigger a response from any ISP and the ISP numbers have been checked and rechecked, and I have checked permissions and done an erase and reinstall
I have a feeling that this computer came from off a LAN and the modem has been in some way inhibited to prevent staff accessing the WWW. Has anybody come across this and is there anything I can do to get internet access.
Any help much appreciated

Wrt54gs & cable modem problem

today i switched from dsl to comcast cable, worked fine until i added my router. i can't get to the internet when my router is inline, comcast is no help except to say the router should not have a compatibility issue with my router, where do i go from here?

Please state the make and exact model number of your modem.
If you know the URL for the User Guide for your modem, please post it.
Please connect your computer directly to your modem (not the router) and do the following test:
Go to "Start" > All Programs > Accessories > Command Prompt.
A black DOS box will appear. Type in "ipconfig /all" (with no quotes), then hit the Enter key. Post the results.

Problems with spotty cable modem connection when connected to 3rd gen Airport Extreme

Hi All, here's my problem:
I've got a 3rd gen airport extreme (AEBS) that I've been using for the last several years and had no issue. Recently, I decided to switch from Verizon DSL to Time Warner Cable, and in order to avoid extra fees, I decided to purchase my own cable modem. Here begins an epic battle with sanity...
- 1st modem Motorolla SB6141: This was the first modem that I bought and it worked like a charm... at first. The first week was like a dream come true, with incredibly fast speeds and very low latency (ping=15ms, dl=30Mbps, ul=5Mbps). The AEBS and the modem got along great, no issues until all the sudden the connection speeds started dropping off. The connection would never fully drop to zero, but close. The bandwidth would hover around 1Mb down, which was about a 1/30 of the speed I was supposed to be getting. I chalked it up to a bad model so I headed back to Best Buy.
- 2nd modem Zoom 5341J: This modem istalled with little issue and worked pretty well. The only problem I encountered with this modem was that it seems to cause a ton of network latency (ping=200ms average), which was way too slow for me. On the first night that I had this modem working, I cycled the power (to try to resolve the latency issue) and it never came back on. there must have been a short in the board or something. Back to Best Buy.
-3rd modem Netgear CMD31T: This modem was an absolute nightmare to get connected to the AEBS. The process involved following a VERY specific order of operations that involved powering down the modem and the AEBS, doing a factory reset on the AEBS, poweing down the AEBS, powering on the modem, plugging the modem into the AEBS, and powering on the AEBS. None of the other modems gave me that much trouble, but when I eventually got it working it was FAST. I was getting the best latency and bandwidth out of all of the modems. Unfortunately, that lasted about 5 minutes, when the bandwidth dropped to 1Mbps and never recovered.
I know what you all are thinking... the problem must be with the AEBS. But here's the kicker, I have an Airport Express that I tested with all three modems and got the same results. Well then (you must be thinking), the problem is obviously with the ISP! But when I connected all three modems directly to my MacBook Pro, they all worked fine, with no connectivity issues. The only time I encounter a problem is when I involve an Apple router. I love my AEBS and my Airport Express, so I'm avoiding buying a different brand router. Does anybody have any suggestions? Thanks for your help!

Well after doing some research, I've figured out that the problem I was encountering had nothing to do with the Airport Extreme or the cable modem! Apparently, my problem was caused my uplink saturation. In other words, my cloud backup service (BackBlaze) was using up all of my upload bandwidth, which meant that ACK packets (acknowledgments) weren't even getting through. This would basically cause any server I was downloading from to stop sending additional packets, making it appear that connection to the internet had been severed. My simple fix was to cap the bandwidth of my BackBlaze backups to about half of my total upload bandwidth. One thing I did learn is that the this issue is usually fixed by using a router with QOS (Quality of Service) capabilities to prioritize ACK packets. Unfortunately, for some reason Apple has neglected to add this feature to even their high end routers.

Can someone tell me how to connect my MacBook directly to my DSL cable modems BYPASSING by wireless connection?SING

Hi all. Can someone tell me how connect my MacBook directly to my DSL cable modem bypassing my wireless connection? thanks in advance.
(the Maverick upload that was pushed out last month will not load for me -- keeps starting and stopping. just read a review where someone had the same issue and once they bypassed their wireless connection, it worked just fine.)

Ethernet.

How do I set up airport on my macbook pro (wired with ethernet to cable modem) and my ipad2 to use ipad wifi?

Vonage between cable modem and Airport Express is a problem

I have my Comcast cable modem connected via Ethernet to the Vonage box which is connected via Ethernet cable to my Airport Express. When I try to connect wirelessly via my Powerbook it's a crapshoot whether or not I can connect to the internet. Mostly the quality is very poor if you can connect at all. If I cut the Vonage out of the equation hooking the cable modem to the Airport Express it works perfect. So Vonage is my problem and I need to change some settings either with my computer or my Airport Express, but which ones? I've been given several different ideas from the information I've sifted through (i.e. change the DNS, change the sharing prefs, get a hard wired router). Oddly enough an old HP computer I have in the basement connected to the internet via another Airport Express has no problems with connection at all. If someone could let me know which of these fixes I am preparing to try would work the best I would appreciate it.

Interesting. So you have two Airport Express devices configured into a WDS, with the one upstairs functioning as the main base station and the one downstairs functioning as a remote base station. And your PC downstairs connected to the remote base station has no problems connecting to the internet. Is that PC cabled to the Airport Express, or does it connect wirelessly to the remote Airport Express?
What happens if you bring the Powerbook downstairs to where the PC now resides. Does the Powerbook then get the same great internet connection as the PC?

Can't find any discussions on this. Suddenly cannot stream video in Safari or Chrome on my iPad 2. The error is "The operation could not be completed." Rebooted cable modem and router, no luck. No problem with my PC. Help!

Suddenly I cannot stream video on my iPad 2. I get the error, "The operation cannot be completed." The browser (Safari or Chrome) continues to try to load the video with no result. I have no problem streaming on my WIndows PC (laptop) using the same WiFi router (Netgear dual band) connected to my Comcast/Xfinity cable modem. I have tried renewing my lease, clearing apps out of memory and rebootng the iPad, still no luck. (How do you do a "hard reset", I forgot?) Frustrating since I don't own a TV and am an Al Jazeera addict! Help!

Cable modem active when MacBook is sleeping

my problem: when my new MacBook17 2.33GHz running OS 10.4.8 is put to sleep, the cable modem does not turn off as it did with My PowerBook G4 running OS 10.3.9. The cable mdem indicates "pc detected" and the data light blinks as it does when the MB is up and running. My PowerBook G4 always turned the modem off when sleeping, back on as soon as I activated it. How do I get the Cable modem to recognize sleeping mode with this new computer?

Not sure.
I've been using a wireless router (Airport-Snow and now Airport Express) connected to my cable modem for so long now but I don't recall my cable modem turning completely off when I put my Mac to sleep or when going to sleep automatically when I used a direct Ethernet connection between my Mac and the cable modem but this was also when using 10.0 and 10.1.
Or do you mean by turning off that the "PC Detected" light turns off?

Problem Connecting Linksys WRT54G to Arris TM402P/100 Cable Modem

The Problem
Cannot get an internet connection attempting to install a Linksys WRT54G router between an Arris TM402P/100 cable modem and the local network.
Prior Configuration
Previously had DSL, with the Linksys WRT54G wireless router between the DSL modem and the local network, which worked perfectly.
New Configuration
This friend recently changed his broadband from DSL to Comcast cable, and he also has phone and television service over the same connection. The installation tech connected the cable modem directly to a desktop computer and left the Linksys router out.
The direct connection between the cable modem and the computer works fine, but he and his wife each have laptops and would like to us the Linksys router to connect wirelessly.
This is the TCP/IP configuration of the FAMILY workstation connected to Comcast

I cannot find a configuration on the Linksys WRT54G that will allow me to connect to the internet through the Arris TM402P/110 modem. Have tried (1) setting the Linksys to use a dynamic WAN address, (2) setting the Linksys to static IP 67.185.155.0 with TCP/IP settings taken from the above configuration, (3) cloning the MAC address of the desktop computer's NIC and trying both (1) and (2) again.
The error message says that the network cable is not connected. Is it possible that the connection between the router and cable modem requires a cross-over cable?
Any suggestions?

on the router's ui... keep the internet type to dhcp....clone the mac address and then do a power cycle...ensure that the modem is completely powered off during the power cycle...if you have a battery back - up , remove the battery...after a minute , put back the battery and then plug in the power cable in the modem...
let me know if this helps you....

My Airport Extreme just stopped working. The message says ethernet cable not plugged in, but it is. Cable modem works fine. Is this a common problem?

My 2-year-old Airport Extreme instantly stopped working last night and is flashing the status light. The problem description is that the ethernet cable is not plugged in... however, the ethernet cable is still plugged into the cable modem. I checked the modem by plugging directly into my laptop... it works fine. Is this a common problem? Is there anything I can try other than sending it in for warranty repair?

At this point, before sending it back, I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Wireless connection of a Macbook Pro to a PC wired to a cable modem

Hi all, I am planning to connect my new Macbook Pro to a wireless network that I will be setting up in my home. Currently I use a wired DSL cable modem that is connected to my PC. My Macbook Pro will be downstairs (wireless) and my PC is upstairs where the cable modem outlet is. I will also want to connect my PC's printer to the wireless network so that my MBP can use it. So....are there any issues I should be aware of regarding connecting, speed issues, compatibility issues, bugs, etc?
Also, what hardware (router, ethernet hub, air-port, etc) do you recommend to make this work? (Mid-range price.)
Thanks very much.

not mid range price but usefullness and functionality for usb connected printers and hard drives and usage for Time Machine backup....Apple Extreme N router educational buy about $165.00

Comcast just replaced my cable modem/wireless router. All devices connect properly except my iPhone 4. It shows itself to be connected to the network, but it does not load any web page. Resetting the iPhone does not solve the problem. Any suggestions?

Comcast just replaced my cable modem/wireless router. All devices connect properly except my iPhone 4. It shows itself to be connected to the network, but it does not load any web page. Resetting the iPhone does not solve the problem. Any suggestions?

Thank you for your response.
I had rebooted the router (several times, actually), to no avail.
I do not know the answer to whether MAC filtering is enabled on the router. Have tried to find info about that, but unsuccessfully. Router is an Arris TG852G, supplied by Comcast. I would be surprised if MAC filtering were the issue, since in addition to the computer, we have successfully connected several other devices to the wifi, namely an iPad, a Android phone and a Kindle Fire - all able to access internet pages through the wifi, and all without a need to add the device to a MAC address whitelist. To add to the mystery, the Comcast tech was able to connect his iPhone 4 to my network and access web pages. He was unable to connect my iPhone, however, after trying for some time.
I seem to recall reading somewhere that an iPhone cannot connect to a wireless "n" router, only "b" or "g". The Arris router is described as a n/g/b compliant router, and as noted the Comcast tech was able to connect his iPhone, so don't know why that would be the issue here.
By the way, my iPhone does connect wirelessly to my network at home. This difficulty is at a second home.
Any other thoughts would be appreciated.

Problems connecting IOS devices with new Comcast wireless cable modem?

Just installed a new cable modem from Comcast, it is their new high speed unit manufactured by Cisco. of the three IOS devices I've tried, all running currently the OS , are having problems connecting with the error "Unable to join the network " Home-XXXX" if you keep asking it may connect but I have to be persistant. My Devices are iPad 4 g Retna with 30pin connection, an iTouch ,latest model with camers, and current iPad mini. is it me or the modem?

You have probably already solved this issue, but I would hide the comcast wifi network (dont broadcast ssid) and make the password very hard. Make sure that put it on channel that does not conflict with your Airport Extream.
Connect the Comcast modem/router to the airport extream's wan port with an ethernet cable.
Comcast usually ships the DHCP enabled. Use the comcast DHCP server for your airport.
Configure the airport extream to "create a network" set the network to "bridge mode".
Name your network, broadcast the ssid all on the airport. Now all your devices will connect everytime. Use can use the Comcast "private" wireless network for maintenance, etc.
Just some thoughts... good luck
