I am FRUSTRATED! My goal is to create a wireless network using an iMac, a Westell 2100 modem (and router)

I started with a PC, the Westell 2100 modem (also a router) and the Linksys WRT54G. I set it up according to instructions I found on the Internet, and it worked fine for YEARS!!! Then, I switched to an iMac. After problems with the setup, I found help on the Internet, and got it working. It has been a long time since then, and I have had to disconnect things, and I do not remember how to set it up. I have searched the Internet, but cannot find a solution. I have searched the community, and followed some instructions here, but I have had no success. I know the following:
The Westell 2100 works as it should. I can connect directly to my computer and access the Internet.
The Linksys WRT54G has not been damaged.
At one point, I had set the SSID and had a WEP/WAP key that is HIDEOUSLY long. Here are some more tidbits: WPAPSK TKIP.
Please help! My new iPhone 4S(teve) needs it's wireless connection to Wi-Fi .

Pleeeze help???

  • Creating a wireless network using several Airport Express(es)

    I would like to connect three AirPort expresses to my Sky Broadband router to create a new wifi network in my house. My router is in the basement and is connected into a hub which provides ethernet to the house. I would like to connect the AirPorts via ethernet to the router and create a single wifi network.
    Can someone please tell me if this is possible and what settings the AirPorts should have. For instance, should I just extend the sky network using each AirPort or should I create a new network with one AirPort and then extend that with the others?
    Many thanks
    Terry

    If each of the AirPort Express devices will be connected using Ethernet, you would configure them all exactly the same except for assigning different device names...AX1, AX2, AX3, etc.
    Each Express will be configured to....
    Create a wireless network
    Same wireless network name on all devices
    Same Radio Mode
    Channel set at Automatic
    Same wireless security setting
    Same wireless network password
    Very important....configure each Express in Bridge Mode
    Post back if you need more details

  • Frustrated trying to set up a wireless network with Bellsouth Fastaccess's Westell Wirespeed modem.

    Today, about 6 hours ago in fact, I came home with a Linksys WRT54G wireless router. It took me a while to get a grasp on how to connect it. I had no network port on the back of my PC, as far as I knew, and I had been connecting my Westell Wirespeed modem to my PC via USB for years. In the end I ended up spending an hour digging up the old Ethernet cable that came with the modem, and finally managed to do everything the Router setup program asked of me.
    One hour after restarting multiple times, experimenting with different orders of plugging in things, and countless resettings of the Router AND the modem, it finally set up the network. It ran for an hour.
    One of my cats ran behind my computer, jarring one of the cords and causing the PC to turn off. It happens twice or thrice a year when they get rowdy. When I jiggle all the plugs back into place and turn on my computer, the connection was dead! Gone! And there was nothing in my Program Files that said "Start Linksys Network" or anything convenient like that. I suppose that would be too easy, right? And my internet didn't work either! So with no other choice, I opened up the installation program again - there was no trace of any sort of folder or application on my PC linked to the router. In fact, as far as I can see, I still have no way to get into ANY sort of router-related application aside from the install CD.
    So I stuck that back in there.
    I've spent the last three hours grueling over this thing. I connect it all before turning the PC on. Nothing. I disconnect everything and plug it all back in meticulously step by step according to the program. Nothing. The install program always gets through the PC checking, and lets me fill in the PPOE (or whatever) information. As it tries to update the router configuration, though, it tells me one of two things.
    1 ) If I have just done a reset of the router, it gets to 99% in the router configuration progress bar before telling me the 'router configuration failed'.
    2 ) If I exit the setup program and reopen it, I get a generic "So and so has caused an error in 4746545x48345675 (or some other random number)," and asks me to either Cancel or Debug.
    My hands are sore and I'm stressed to the limits. I bought a laptop a week ago for the sole purpose of alleviating the battles my kids have over the only source of internet in the house, but it's just been sitting there. I'm really at the end of my wits. Between the errors that don't tell you what went wrong and the perfectly-connected router that keeps pretending it's not connected, I'm just about ready to return the laptop.

    This happened to me when I was setting up the wireless router for a friend.  The issue is with the Westall modem.  You need to go in and setup the "bridge" option on the westell modem.  The link below gives directions or you can call bellsouth dsl support (this is how I learned about it).

    Good luck
    Solution:
    Method 1 - Hard Reset
    Restore the modem to default settings by pressing the Reset button on the back of the modem and holding it for 3 seconds. (Bridged mode is the default setting for the Westell).
    After the modem regains sync, it is in Bridged mode. Do not attempt to surf into the modem as surfing into the modem will enable the Easy Login page and convert the modem from bridged mode to a PPP mode.
    Method 2 – Bridged Mode
    Access the Westell interface using http://192.168.1.254 or http://launchmodem.
    Click on the Broadband DSL Line button. 
    Click on the Protocols button 
    Select the radio button to the left of Option 2 (Bridge)
    Click the save button. Once the modem has restarted it is in bridge mode.

  • How do I create a wireless network using iMac as base station

    How do I set up a wireless network using my iMac as the Base Station and boosting the signal through an Airport Extreme? 
    Physical connection would be DSL Modem> (ethernet) iMac >(wireless) Airport Extreme (as a wireless router for other Apple products i.e. TV, iPhone, etc.)

    How do I set up a wireless network using my iMac as the Base Station and boosting the signal through an Airport Extreme?
    Unfortunately, the wireless network that is setup from the iMac cannot be "extended".
    Your setup will need to include two Apple routers and look like this:
                                                         > Ethernet to Imac
    DSL Modem > Main Apple Router    >>>Wireless to nearby wireless devices
                                                         >>> Wireless to Extending Apple router
    You may also connect the iMac to one of the Ethernet ports on the Extending Apple router if you wish

  • Can't create a wireless network without a wireless card on my Mac

    Help!
    O.k. I tried searching the forums for an answer but the odd nature of my problem, and the immense database of topics made it very difficult to find a similar post.
    The general issue/idea:
    Run a wireless network using Airport Extreme - Connect desktop mac via ethernet and Roku player via wi-fi. Can't get the desktop mac to connect via ethernet when I restart the network/Airport Extreme.
    My Father in law has my old computer; It's a PowerMac G5 (Dual 1.8GHz CPUs) running OS 10.5.8), connected to internet via cable (TimeWarner) modem. It does NOT have an Airport or Airport Extreme card installed. The computer works fine, and I don't believe that I 'need' an Airport Card in order to use the Airport Extreme (it's a brand new/refurbished model) in the manner described below.
    I would like to use the Airport Extreme to generate/run a wireless network (Do I need an Airport Card in order to generate/run a wireless network? Doesn't the AE actually do that?), connect the desktop Mac to the network via Ethernet (I shouldn't need an Airport Card to do that, should I?) and connect a 'Roku Player (802.11g capable) to the network via wi-fi.
    As far as I know, this should be possible.
    Basic steps/as I understand them:
    A. Connect ethernet from cable modem to AE.
    B. Connect ethernet from AE to desktop Mac.
    C. Create the wireless network using desktop Mac and Airport Utility.
    D. Restart AE to start the wireless network running.
    E. Connect Roku to wireless network over wi-fi.
    I have no problems with A & B. Once the AE is connected to the desktop Mac, I'm able to get internet via ethernet as it passes through the AE. I can then create a wireless network (step C.) using the Airport Utility (and setup assistant). The problem starts after I've configured the wireless network.
    Once I've configured the wireless network, the Airport Utility software prompts me to restart the AE in order to start the wireless network.
    As soon as I restart the AE, my desktop Mac tries to connect to the 'wireless' network, even though it's already connected via ethernet. I don't have a wireless card in the Mac, and I don't want to connect the desktop using wi-fi/wireless. It's connected via ethernet, works fine during configuration, and I don't ever anticipate a desire to connect the desktop via wi-fi.
    No matter what I do, I can't get the desktop to connect via ethernet. The only network connection option I'm offered is 'Rescan'. O.k. the desktop can't find the wireless network (because it doesn't have a wireless card), and I'm unable to continue with the Airport Utility. I can't make any further changes to the network (the options to manually change the network configuration are not available as the desktop Mac cannot currently talk to the AE - It's still trying to connect wirelessly), and the desktop has no internet connection as it's trying to connect wirelessly.
    *How can I...*
    *Setup/run a wireless network, while keeping the desktop Mac connected via ethernet?*
    I'm perfectly willing to factory reset the AE and start over.
    Any help appreciated.
    Thwarted by the network.
    - Robert

    My Father in law has my old computer; It's a PowerMac G5 (Dual 1.8GHz CPUs) running OS 10.5.8), connected to internet via cable (TimeWarner) modem. It does NOT have an Airport or Airport Extreme card installed. The computer works fine, and I don't believe that I 'need' an Airport Card in order to use the Airport Extreme (it's a brand new/refurbished model) in the manner described below.
    That is correct, you could connect the PowerMac G5, via Ethernet, to the AirPort Extreme Base Station (AEBS) or any other wired router for Internet access. You do NOT need an AirPort Card for wired access ... ONLY if you want the G5 to connect to a wireless network.
    I would like to use the Airport Extreme to generate/run a wireless network (Do I need an Airport Card in order to generate/run a wireless network? Doesn't the AE actually do that?)
    That is correct, the AEBS is a wireless router that can provide a wireless network. The AirPort Card, on the other hand is a wireless adapter used to allow a Mac to connect to a wireless network, created by any wireless router ... not just those provided by Apple.
    As far as I know, this should be possible.
    Basic steps/as I understand them:
    A. Connect ethernet from cable modem to AE.
    B. Connect ethernet from AE to desktop Mac.
    C. Create the wireless network using desktop Mac and Airport Utility.
    D. Restart AE to start the wireless network running.
    E. Connect Roku to wireless network over wi-fi.
    Yes, these are all good assumptions.
    As soon as I restart the AE, my desktop Mac tries to connect to the 'wireless' network, even though it's already connected via ethernet. I don't have a wireless card in the Mac, and I don't want to connect the desktop using wi-fi/wireless.
    Do you actually have an AirPort Card installed in the G5 now? If so, then it might be possible that the "firing order" for network connectivity has AirPort at the top of the list under System Preferences > Network. Just change the order to have Ethernet at the top and disable AirPort to ensure that the G5 connects by Ethernet only.

  • Can either the Airport Express or Airport Extreme be used "standalone" to create a wireless network with access to the internet?

    I want to create a wireless network for my iMac, Macbook Pro and iPad, and I'm confused about the Airport Extreme and Airport Express devices.
    There is mention for both about connecting them to a DSL or Modem. Does this mean I have to obtain additional hardware before they will enable connection to the internet? (In the past, I've used a Belkin Router, which simply connected to the phone line.)
    Any advice gratefully received.
    Tony

    Does this mean I have to obtain additional hardware before they will enable connection to the internet?
    Yes, you need a modem. The AirPorts are routers only. They do not have a modem built in, so you will need a modem if you want to be able to connect to the Internet.
    The Belkin device that you have used before is a modem/router.  It combines the functions of a modem and router in one package.

  • Can I create a unique subnetwork when extending a wireless network using Airport Extreme?

    My office building has an Airport Extreme to provide wifi to our individual suites.  I would like to create a sub-network using my Airport Extreme for my suite only that uses the wifi signal from our office building and provides internet to the computers (both wired and wireless) in my suite but have it protected so that other suites in my building can't see my computers.  Is this possible and how do I do it?  I have currently set up my Airport Extreme in wifi-mode "extending a previous wireless network" and have the router with its unique router name.  But once I extended the wireless network, I could not find the network name of my router, only the office name (the one I was extending).  The computers connected via ethernet to my Airport have internet access but none of my wireless computers see my airport name, it sees the office building network name.  I'm assuming they are connecting to my Airport since the signal level is much higher than before and it appears that my Airport is rebroadcasting the network name of my office building.  Is there a way to have my Airport broadcast its unique identifier for wifi, still connect to the internet via wifi signal to the Office building airport and maintain segregation between my computers and the rest of my office building?
    Also, when I use the Airport Utility on my Iphone, I see the internet -> the office airport extreme -> and then 2 different base stations connected in a Y.  Mine and my neighbors (who is probably doing the same thing as I am).  But there is a dotted line to my base station, does that mean I'm connected to the internet via my neighbor's airport?
    Any thoughts?

    I would like to create a sub-network using my Airport Extreme for my suite only that uses the wifi signal from our office building and provides internet to the computers (both wired and wireless) in my suite but have it protected so that other suites in my building can't see my computers.
    It is not possible to configure a single Apple AirPort router in this manner using wireless only, but it would be possible to do this with a single AirPort if you connect your AirPort Extreme to the "main" router using a wired Ethernet connection.
    As for wireless only....you could probably do what you want by using two Apple routers....an AirPort Express to join the wireless network and provide an Ethernet signal to the AirPort Extreme's WAN port. Then the AirPort Extreme could then be configured to provide a separate network using a different subnet.
    Users on the "main" network would not be able to "see" any devices on your "private" network and vice versa.
    I use the two router set up all the time at hotels that only provide a wireless signal. The first Express "joins" the wireless network and feeds an Ethernet signal to the second AirPort which is configured to "create a wireless network" in router mode.
    This way, I can connect multiple devices to my "private" network, but only pay the hotel for one connection since the hotel router only "sees" the AirPort Express that joins the network.

  • Time Capsule - Can it run as DHCP router, create a wireless network and plug into switch for wired network all at the same time?

    I have a closet with Wired connections from all over the house terminating in it. I also have the internet modem and a switch in this closet. My old setup was a netgear in the closet creating a wireless network and also feeding the Ethernet ports all over the house. In my room, I had an Airport express (a month old) bridging the wifi to make the wifi network larger. The Express was hard wired from the wall and my mac mini was using it's wifi (printer was plugged into other ethernet port). Everything was working great.
    Fast forward to last week. My Netgear died. So, I bought a time capsule. My plan was to move the Express to the closet and have it create the wifi network and also then run cat 5 cord from express to the switch to feed all the wired wall plugs. Reset it and set it up to create the wifi network as well as DCHP NAT. Wireless was running great on it. Then I plugged in the Cat 5 in the second Ethernet Port to the switch. Wifi stopped working and none of the computers would connect using wired connections either. They would see a 'network' but nothing would work. I would unplug the Cat 5 feeding the swtich and the wireless would start working again. Plug the Cat 5 back in and wireless would stop.
    So I thought I would try the Time Capsule in the closet and see if I could get it to work. Pretty much the same thing, except at this point I figured out if I went in and told it NOT to create a wifi network the wired portion worked fine and all the wired computers in the house worked fine. Of course, then I didn't have Wifi.
    I'm not clueless when it comes to networking, but I can NOT figure this out! Can either the Time Capsule or Express Create the wifi network AND also feed the data to the switch for all the wired computers?
    To simplify this is what I want my end result to be. I prefer the Time Capsule to be the wireless connection extender, but if I have to have the Express do it, I'm fine with that.
    1. Express in the closet creating the wifi network as well as feeding the data to the wired connections via my switch.
    2. have the Time capsule in my room at the opposite end of the house plugged into the hard wired connection to extend the wrieless network as well as have wired connections such as my printer and my Mac Mini.
    If I can get #1 to work, I don't think I'll have any problems with #2. Help!

    I have an equally complex setup with a managed switch actually but I have never seen the TC have this kind of issue.
    What I do notice is you have changed the TC from defaults.. you are using a non-default IP range.
    I have run across issues like this where people move things from default.
    I would like you to start over.. factory reset the TC. That will set it back to default router mode.
    Do the min setup on the TC..
    1. Change all names from what you were using. That includes the TC name and wireless name/s
    Make them short, no spaces and pure alphanumeric because that is the correct way to network. Apple default names with spaces and apostrophes are fundamentally bad.
    2. With just the TC plugged into the switch.. and a single computer connected by ethernet. Power cycle the whole network.. this allows the switch to clear all the old MAC address.
    3. Test on the computer just ethernet. Turn the wireless off.
    The computer must use dhcp and must get an ip from the TC.
    It has to get the correct Router.. ie Gateway.. I wish apple could stick with proper network terminology.
    And it must get same address or valid DNS server address/es.
    If it fails.. please plug ethernet directly to the TC.. bypassing the switch.
    You should get the standard IP addressing and internet connection.
    If not please post the screenshot from the Mac of the network preferences showing the ethernet setup.
    I need to see what address it does get. I need you to make sure the ethernet is the TOP of the list. So rearrange the order of network connection. With the airport off it should just go to the top of the list.
    If it appears to be working .. but a browser cannot connect, open a terminal and ping an internet address.
    Ping the actual gateway address the ISP gives you and ping the ISP dns address.

  • I have Fios. I have the TC connected via ethernet to the Fios router. TC WAN port ethernet to Fios Lan port. Then I just have the TC create a wireless network that is different than the Fios wireless network. How do I set up an Airport Extreme to the TC?

    The Airport Extreme is a 4th Gen unit. I just want to keep the TC wireless name to go further through my house.

    The Ethernet connection will be from one of the LAN <-> ports on the TC to the WAN port (circle of dots icon) on the AirPort Extreme.
    Then you can use AirPort Utility - Manual Setup to configure the AirPort Extreme as follows:
    Click the Wireless tab located just below the row of icons
    Wireless Mode = Create a wireless network (Not "extend a wireless network" as many users incorrectly think)
    Wireless Network Name = Same name as your TC network
    No check mark needed next to "Allow this network to be extended"
    Radio Mode = Automatic
    Channel = Automatic
    Wireless Security = Same setting as the TC network
    Wireless Password = Same setting as the TC network
    Confirm Password
    Click the Internet icon
    Click the Internet Connection tab
    Connect Using = Ethernet
    Connection Sharing = Off (Bridge Mode)
    Update to save settings and restart the entire network
    Computers on the TC network will now be able to move to the area where the AirPort Extreme is located and not have to "switch" networks. This is known as a "roaming" network.

  • How can I create a wireless network in my office for my itouch?

    I am in an office Windows environment with a G3 Mac that is connected to the internet via the Ethernet port. I can get to the internet with my Mac through a Proxy server. I have tried to setup up Airport to get through the firewall without any success. Is it possible to create a wireless network for my itouch if I install an Airport card in the Mac, start Internet Sharing and install Airport Express? I have no experience with the Internet Sharing options in OSX. I am assuming that my Mac with an Airport card would pass the internet connection to Airport Express. Airport Express would then create a wireless network for my itouch to connect to the internet. Any advice is appreciated as I would really like to get to the internet with my itouch.

    You don't need the AirPort Express to do this.
    You can set your Mac to share it's wired connection over the wireless port and the iTouch can connect directly to the Mac.
    You could also do it with the AirPort Express, but you don't need to - it's overkill for what you've described.

  • I have a canon scanner MP560 wireless. Needed to create new wireless network and now my computer can't find the scanner/fax..

    My iMac doesnt' see my Canon MP560 wi fi scanner ever since I created a wireless network in my house.  Can't find a way to change whatever settings i need to to connect the scanner. help.

    Well let's see if we can help you get set up. Have you got any 2.4 GHz cordless phones in the house and if so try unplugging them and do a hard reset of the express.
    1. unplug the express
    2. press the reset button
    3. while pressing the reset button plug in the base station
    4. keep holding the rest button till you see 4 green lights flash
    you may have to hold it for 30 seconds or so
    if this doesn't work try plugging the express in right beside the computer and then going through the airport setup assistant
    Good luck

    In addition to RyanJC's comments, the 802.11n AirPort Express Base Station (AXn) can store up to five different http://docs.info.apple.com/article.html?artnum=108081 configuration profiles. You will need to use the AirPort Utility to create & save these profiles.
    To create a new profile:
    Open AirPort Utility, select your AX from the list, and then, click "Manual Setup."
    From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
    Click "+" to create a new profile; give it a name, and then, click OK.
    Set options, such as network name, passwords, Internet connection method, etc.
    When done setting the options, click Update.
    To switch profiles:
    Open the AirPort Utility, select your AX from the list, and then, click "Manual Setup."
    From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
    Click on the desired profile, and then, click OK to apply the new profile and restart the AX.
    Just remember to switch to the desired configuration profile before removing power from the AX.

  • Using airport Express on a hotel ethernet to create a wireless network

    Hi there, yesterday I bought an airport express as I was lead to beleive it was the perfect device and simple to set up with regards to creating a wireless network from a ethernet connection in a hotel room. I seem to get a green light and seem to aquire a valid IP address of 192.168.2.102 and the AE utility doesn't state I have any problems and yet I cannot connect to the internet. I am from the UK and currently in Honk Kong on business for the next few days and desperately need to get a wireless connection sorted. I have read through many of the archives on these forum pages and it is still not certain to me whether I should be using bridged mode or not?
    btw, I can connect my pc and get internet access without any problems by ethernet directly into my pc.
    can someone advise me of the settings I should use given my scenario (ethernet connection in a hotel room). Given how much tme I have invested trying to get the AE to connect to the internet I would prefer to stick with it and get it workShort rather than taking the Airport Express back to the Apple store tomorrow and moving to a hotel with wireless and not ethernet connection.
    Help appreciated
    Russellb

    Hello, thanks for your suggestions. I have tried setting up the AE using my girlfreinds Win XP computer instead of my vista one and it setup 1st time without any problems. In fact, the options I got presented with were slightly different. Shocked at what a difference installation and setup can be from using a Vista laptop to a XP netbook. Maoin thing it is now working and you were correct about using it in bridged mode so many thanks.
