Antenna on iMac G5?

Hey, I got a Airport Extreme card, and I want to hook it to a big wi-fi antenna on my roof, what type of connector does the Aiport Extreme Card have, and is it posible to make 3 or 4 antenna into 1? Also, can I use multiple internet connections at once (Ethernet and 2 or 3 Wi-Fi, even just 1 Wi-Fi?) Do you think I could get a cheap G4 and put a ouple PCI wi-fi cards in it and use it to merge all the connections? Thanks for any help, I just like messing with stuff, and am stumped.

It'd be pretty difficult to hook an external antenna into an Airport Extreme card built into an iMac G5. You'd be better off getting a PCI card which has an SMA connector for an external antenna and putting it in the cheap G4 you mention. As for using multiple WAN connections - why? It is possible - you could set up the machine as a firewall/router, and create a routing table for it all, but it's not a 5 minute exercise.
I can think of two uses for this - the first is to have multiple connections to a wi-fi provider via one account. If the ISP uses any sort of reasonable authentication method, there's no way this will happen. The second is that you want to use neighbour's wi-fi connections which you've left unprotected, in which case you're on your own.

  • Use tv as imac monitor

    How to connect 27" imac to a hdtv (samaung UN55B7000) and use it as a second monitor?

    Guy,
    I've a done a similar connection between my TV & iMac 27" and I do get both audio and video out from the TV, when connected.  I works flawlessly, when connected.
    The issue I've is, when I want to watch something else on the TV, and I change the input from the HDMI to Antenna, my iMac assumes the TV is still connected and displays my secondary screen on the TV (hidden).  It switches back to single display mode when I remove the connection.  I tried to power off the TV (not standby), but the imac still thinks that a live displays is connected.
    Do you guys keep the hdmi cable always connected. 
    Do anybody has similar issues like me.
    Thanks & Regards

  • Airport antenna -second gen iMac-G5

    I am unable to locate where the antenna wire is located on a second gen iMac-G5 -20" 2.0 Ghz M9845LL/A. There is no separate airport card in this model ?
    I am having difficulty with signal level so I thought it might be ralted to loose
    antenna connection .

    I think I have the same problem with a friends iMac G5 with ambient light sensor. 17 model. The motherboard looks nothing like the ones on the manuals. I think the airport card is part of the motherboard. So the airport card is broken, thus causing kernel panicks. You can boot in safe boot mode and it works fine since it disables airport.
    So now people who own these machines with built in cards are screwed. They can't just replace the extreme card with another one. You'll need to replace the logic board. You can't add a USB wireless card because you can't remove the built in airport card to get rid of it. So what do they do now?

  • External Antenna w/new iMac

    Hey Folks,
    Brand new to Mac and I was wondering if there was anyway to add an external wifi antenna to my new 24" iMac?
    My Modem is on the other side of the house, 2 floors up and I can't seem to find a signal.
    My Dell PC right beside it has an external D-Link 7.5DB high gain antenna and it finds several access points.
    Any ideas???

    Can you run an ethernet cable down the cold air return and use that? You also might relocate the existing wireless router to a better location on the floor it is on. Or run a second router from the first using ethernet and extend the range of the network that way. I ran an ethernet cable through the cold air return from the 2nd floor to my basement and I have a 5 port switch and a second router acting as a wireless access point there as well. They are cheap as borscht nowadays.

  • Failing/ed imac crt antenna or failed airport card?

    running on dsl via airport. airport signal started to fail intermittently after a few minutes. this started after son got a power book after his crt with airport failed on an oldert crt model.
    called mac asssistance and for a fee they could not help me other than the old move/turn off the portable phones. the thing always worked before with the portable phones nearby so they suggested "external" interference. I asked about airport extreme and they said yeah, try that, more robust at zeroing in on frequency. bought airport extreme after first consulting genius at genius bar in clarendon who assured me it is the built in antenna not the airport card. he had no airport card on hand to test my computer (does not do obsolete thank you). he was flip and certain and suggested i just junk the thing since the repair is very expensive or try an external antenna from quickertech which apparently does not exist (antenna not company). i can get signal using ethernet connection and can get the airport to work sometimes when the computer is cold. as the session contnues, the signal fades and stops. i am exasperated that mac has dropped support for this product so soon after it made them millions. anybody had the same problem and found a solution? otherwise my next step is the repair facility. this is a sweet machine not going to a dumpster in the name of conspicuous consumption.

    This is a duplicate post. I replied to your other post last week and you didn't respond to that reply. Basically i said there that I have never heard of the antenna failing in an apple computer. A solution however may be an external ethernet wireless bridge since they have an external antenna. Perhaps others have more to add though.
    Did you actually try turning off any nearby phones? You seem to dismiss the idea because it always worked before, but they could be contributing to interference, or someone elses phone could be. What about moving the computer? Does it help if the computer is closer to the base station?
    Dropped support so soon? Airport hasn't been made in a couple of years now, and its not like its not supported at all, they just don't make them at all. Apple is glad to help you if you pay them for the privelege, same as for every other product they make. All the software they amke works with it just fine, which is kind fo the definition of supporting the technology.

  • I have purchased a Imac G5 20" Computer. I does not have wireless, so I purchased and airport card to install. after opening the computer, there is no metal stand to install the card. i ordered a stand on Ebay. Do I need to buy an antenna too?

    Any help or suggestions are greatly appreciated.
    I am a first time Apple user and first time Support Community user.
    If anyone has any other upgrade suggestions or something you would do to this unit, please let me know.
    Mainly bought it to interface with an iPad down the road, but i need wireless internet.
    The ethernet cable works fine but not in area where I want the computer.
    Thanks !!!

    Yes, you will need an antenna as well.  You will probably want to add more memory, you can have up to 2GB (an iSight can take 2.5GB), and depending on the size of the drive, you might want to put a bigger one in as well.

  • Wireless signal from iMac to TV?

    I have a new 20" iMac G5 isight on the way and have a question. Has anyone tried to hook up the iMac (or other mac) wireless to your TV. There is products like this www.amazon.co.uk/exec/obidos/ASIN/B000068TYR
    ref=erra_acc_dp1/026-6032989-4654855 that will send a signal from your antenna to your TV wirelessly. I thought mabye in combination with a TV tuner like EZ there would be a way to get the signal from the mac to the TV. That way I dont have to drill a cabel-hole in my livingroom floor down to my office to enjoy FrontRow on my TV. Or is there any other solutions/suggestions?
    (And i dont think there will be an Airport Express A/V launched next week... though I wish!)

    You should be able to connect your ATV directly to your iMac using Internet sharing, but you can't use the same NIC that the iMac is using for its connection. If your iMac is connected to your router by wi-fi, you can share the Ethernet port with the ATV. If your iMac is connected to your router by Ethernet cable, you can share your iMac's AirPort with the ATV.

  • IMac to TV (HDMI) : Ghost display when TV is off

    Hi, 
    I'm using my Sony TV (40BX420) as my secondary display for my iMac 27", connected via
    MiniDisplay Adapter+HDMI Cable.   When connected everything works fine, the
    audio & picture appears normally.  I use this setup to watch movies on my bigger screen.
    I always keep the hdmi cables physically connected between the TV & iMac (which is always on).
    The problem is when I switch the input on the TV from HMDI to Antenna (to see the TV channels), the
    hdmi appears active to my iMac, and the audio & windows which was getting displayed on the TV, does
    not reappear on my iMac. 
    The only solution to my problem is to physically disconnected the hdmi cable when I do
    not want to watch the computer content on the TV.  
    I'd an older Toshiba TV, when I connect the same hdmi cable to this tv.  As soon as I change the input
    on the TV to HDMI, the iMac responds, with activating dual monitor, when the change the input, or switch
    the TV off (standby) the imac goes back to single display mode. 
    I call sony, their tech support is horrible, they told me it a feature of their TV, it keep the HDMI active in standby mode.
    I tested this buy shutting down the power on the TV, but the iMac was still behaving as if connected and I've a ghost display
    on the TV.
    Please let me how can I solve this issue.   They may quite a few of you who is connecting their iMac to TV
    Sajid

    hi there,
    have you solve this problem?
    Because I have had this issue also, still looking for the solution.
    Thanks

  • Imac sees no wi-fi networks. Other computers do! Some input needed!! Thanx!

    Hi people.
    I just got a intel imac 20inch with an airport extreme card. A few weeks ago i tried looking for networks.
    At home i found 8 wi-fi networks in my area with help of a windows laptop. My mac...detected nothing.
    I went back to the shop (a shop with apple certified people) to let them check it.
    Their conclusion was that my card was functioning correctly.
    The receipt stated that they streamed a movie through airport and that there was no noticable delay.
    Their airport base station was located a few floors above their technical dept.
    I got my mac back and i went straight to home. Same problem. No networks whatsoever...
    Then i went to my friends house. He's got a old dell with a sitecom wlan card.
    He can find 4-5 networks in his area. My mac can only find his network. I use Istumbler + Spectrum Widget and the strenght is 50% on a distance of 1,5m (5feet) to his router!
    How is this possible?
    I know that to access another network you need some data. But to detect a network with it's SSID on you just have to turn airport on to see it. Right?
    I reinstalled osx and i am doing a software update right now. To 10.4.7.
    Maybe that helps but i doubt it.
    Can anyone shed some light?
    Should i go directly to apple and have them look?
    Thanx!!!
    Intel Imac dual 2,0 Ghz   Mac OS X (10.4.4)  

    The software update is done. No improvement.
    I saw another post with an answer from duane wich made me think that the antenna of my airport extreme card is not inserted properly.
    Unfortunately the new imac's are not opened easy.
    I hope that's it. After all.....they did not open my mac. Sigh.
    I'm gonna call apple care.

  • Procuring and installing a bluetooth card for 1st gen imac G5

    Hello,
    I'd like to install an internal bluetooth card on my early G5 iMac. Can I do that? And if so, how would I go about it?
    Thank you so much,
    Sincerely,
    Tabeer

    There are three things you need to install the Bluetooth card on the iMac: the card, the antenna, and a small bracket for the end of the antenna.
    I looked on the web just today to find the answer to that and most all said it can not be done. I just installed one on a 1.6 MHz G5 iMac. I piulled the components off a 1.8 MHz G5 iMac.
    You need to be comfortable opening the iMac. I had almost nothing to lose here because my 1.8 MHz failed (capacitors) and I had done quite a bit to try to resurrect it - I had the mother board out of the machine. Interestingly, to do this operation, you actually do less dissassembly than taking the mother board out. The trick is to leave the mother board in the frame, and remove the frame from the case (white thing with the LCD screen).
    More specifically:
    notice that the airport antenna (follow from the Airport card) disappears under the mother board near the lower left corner (face down);
    just below the airport card is where the bluetooth card goes - plugs in w/connector and two screws.
    remove the power supply;
    remove the optical drive;
    remove the hard drive;
    disconnect the LCD panel connector - 2 screws;
    disconnect two connectors on the left side (as you are looking at the thing face down) - one is under the optical drive, and the other you have to follow the cable you just disconnected down under a slender grey plastic component (Airport antenna part?) Take that component out too - 1 screw;
    remove three screws across the top, just below the top edge of the case (white thing);
    remove three more screws - one at each bottom corner (face down) and one mid way up the left side (these screws have coarse wood threads vs machine threads);
    tilt up the metal frame with the mother board attached and lift it out.
    the bluetooth antenna goes through a small "hole" in the sheet metal and then follows a bundle of black and brown wires to the right (face down) - there are 3 or 4 "tabs" made out of the sheet metal;
    there is a distinct bend in the metal frame where a plastic bracket is glued in place and holds the end of the antenna, which has a printed circuit board about 1" long by 1/8" x 1/8".
    It was relatively easy.

  • Airport card is not recognized by G3 iMac

    I recently acquired a G3 600 MHz iMac, running OS X 10.4.11, and I want to join the iMac to my wireless network. So I purchased an Airport card ( tested card on a ibook running 10.4.11 and it works fine.) and seated it in the G3 iMac. For some reason the iMac does not recognize it one bit. I checked profiler and System Preferences and no sign of an Airport Card. I then opened the iMac and reseated the card, I even changed out the adapter with another adapter I had. After researching online, some people suggested an archival OS restore. Although I would try that but unfortunately I do not have any of the original install disks. So my question is: does anyone know how I can make the os recognize the card?
    Greatly appreciate the help.

    There are two versions of the original AirPort card, and their identify can be determined using the information below.
    The poster you replied to may be referring to this post quoted below, though even if he had the initially issued card, it would not explain why the card is not recognized. Though incapable of supporting advanced security, it would otherwise be recognized and operate as expected if seated properly, as you have described.
    The original AirPort card was equivalent to a WaveLAN Silver card, and supported only 40-bit WEP or 64-bit encryption, and did not support WPA.
    The original AirPort Base Station which shipped with these cards on board was limited to 10 clients, had only a 10BbaseT LAN port, and supported only 40-bit WEP. Later cards which looked physically identical, supported 104 bit WEP, or 128-bit encryption, as did the AirPort Base Stations which included them. This second card, also manufactured initially in the Netherlands for Apple by AT&T's Lucent unit—later know as ORiNOCO—was equivalent to the WaveLAN Gold card.
    The 661-2219 part number is distinguished by the M7600LL/* marketing designator screened on the label, as well as engineering revision part number 825-4889 and worldwide procurement part number 630-2883. EEE code G3G is embedded right-most in the last four characters of each part's serial number. *This character is typically A, B or C.
    The 661-2569, on the other hand, is distinguished by an M7600LL/D or later marketing designator, engineering revision part number 825-5620, the same worldwide procurement part number 630-2883 and typically the phrase '128 bits' along the lower center of the label. EEE codes LH8, M6Y or QAC are embedded right-most in the last four characters of each part's serial number.
    While a procurement number generally changes when a service part number change is made, this product did not, as Lucent remained its sole supplier, the 'change' to the card involved different firmware and not a physical change to the product, and Apple personnel largely considered them equivalent, though they were and are not.
    Graphite AirPort base station models initially used the M7600LL/A, B or C cards, and was itself designated the M7601LL/A and later, the M7601LL/B. Both base stations were also designated as 661-2265 whole unit service replacement parts. Every card we've ever seen in a Graphite base station was a 661-2219 and was marked as described above.
    Apple did not adequately document many of these parts and there applications at the time they were still in use, and all have disappeared from their inventory—except in limited cases—as has much of what existed for documentation. Given their personnel changes over the years, it's quite likely that no one there now can recall the subtle differences or properly identify these products. Once there are designated vintage, then obsolete, they drop quickly off of the radar.
    While any properly functioning iMac compatible AirPort card properly mounted in a 076-0804 adapter would show up in the System Profiler without the antenna connected, the performance of such a card would be poor to abysmal.
    I believe that you are completely correct when you indicate that either the adapter is not seated properly, that it is not working properly, or that the logic board is defective. The latter two scenarios are quite unlikely, though possible.

  • IMac no longer connects to Wi-Fi on startup or after manual sleep

    Hello folks,
    I need some suggestions. Here is a description of the problem (as brief as possible):
    My late '09 21.5" iMac spur-of-the-moment didn't connect to my wireless network on a random day (2 or so weeks ago). I thought nothing of it, until I noticed it happening after I put it to sleep that same evening. I turned it off hoping it wouldn't happen again.
    It did.
    I have since been in contact with an Apple support person (it's still under warranty) and haven't talked to him in a while. I'm going to call him within the next few days (back in school now) to see if he has any solutions. Here is some more info without stories:
    Tried:
    Deleting preference files (all related to Airport and System Configuration
    Removing the Airport service altogether and adding it back on
    Turned router off and back on
    Changed routers completely (from an old Netgear to a new Netgear from Comcast)
    Turned modem off and took backup battery out
    Removed all references to wi-fi networks in Keychain Access
    Turned Firewall off in Sys Prefs and in Antivirus software (which will be deleted soon)
    Removed any unused login items/programs
    Other tidbits:
    Only happens at start-up and when I put it to sleep (not if it goes to sleep itself)
    Message pops up about no preferred networks being available as soon as my desktop loads up (my network is always on the top with 5 bars)
    Nothing changed on my Mac or Internet or environmentally
    During these changes I've restarted my Mac some 20 or 30 times.
    Running 10.6.4 and have all updates.
    Trust me, many things were covered in our 3 hour phone conversation. And as I said earlier, I will be calling him soon.
    I have never had a problem with my Mac before and am curious as to why this has happened so spur-of-the-moment.
    If you need any other specs, please ask.

    My previous 27" iMac is also '09 model just like your 21.5" iMac. I had the same connection issue as what you have described. But once the wireless connection had been made manually, the connection was rather reliable with reasonable bandwidth and without dropped connection. The problem was not resolved until Apple released updates for Mac OS 10.6.4 and transmission power of wireless router was increased to maximum. I suppose the problem was partly because of changes to aluminum unibody casing and smaller antenna. The only difference between your setup and mine is different wireless router (Netgear vs Airport Extreme).
    If you are confident on good signal strength, perhaps execute Software Update from Apple icon on main menu bar to make sure that all updates have been applied properly. Last resort is to reinstall Mac OS 10.6.4 from scratch with all updates applied. There is also one easy way to monitor signal strength after connection has been made manually, pressing on option key while right clicking on Airport icon on main menu bar. The field RSSI indicates signal strength in negative dB value (smaller negative value means higher signal strength).
    If you do not want to mess with the Netgear wireless router, one way is to bypass iMac built-in antenna all together by using Airport Express. Based on my regular monitoring of signals on iMac and Airport Express, Airport Express has much higher and consistent signal strength than unibody iMac. Plug in Airport Express on power socket outlet near your iMac, connect a Ethernet cable from iMac to Airport Express and use Airport Express as wireless bridge between main Netgear wireless router and iMac. Better still if you can afford to discard the Netgear router, just replace Netgear with Airport Express all together and use newer 802.11n protocol instead of older 802.11b/g protocol for better speed and range (assuming the Netgear router does not support 802.11n protocol). The Airport Express can also be doubled as base station for sharing printer and speaker in wireless network.
    Apple has to assume responsibility to ensure all its Airport wireless products work properly with all models of Mac whereas it is different story for other brands of wireless products. I once was using Belkin wireless router but had to switch to Airport Extreme/Express because of issues occurred whenever Apple released updates for Mac products. If there is problem between iMac and Airport Express rather than Netgear, there is no reason Apple technical support can ignore the problem (particularly if you have purchased AppleCare for your iMac which cover all Apple accessories as well).

  • Brand new iMac, no internet

    I got my new 2012 iMac 27" yesterday, and from the very start (the initial WiFi setup), it hasn't been able to get any internet. My other Macs and iDevices are fine with the same wireless router, and I've tried the new iMac with a second wireless router, and it's still not working. It connects to the wireless networks, but cannot send or receive data. I've tried Network Diagnostics several times with no luck. Any suggestions? Thanks for the help.

    I would try checking the routers setup if it's set to use MAC address filtering (MAC is not releated to Mac as in the computer it just happen to be the same term)
    if it does then you need to
    1. add the MAC address of your wifi card on the imac to the list of allowed devices
    or
    2. disable MAC address filtering
    if that didn't pay off then I would just to be sure
    go to the router makers site to check if there were a newer firmware for the router
    they fix bugs often and put out better working firmware
    if that didn't pay off then I would try to brign the imac to a friend or family who have wifi too and test if it works there to see if the imacs wifi card was defect as in the antenna inside could have broken or something

  • Three devices on network: 100% packet loss for my iMac.

    I'm having intermittent bouts of 100% packet-loss pinging my router from my iMac, at the same time my iPod touch and neighbor's Windows laptop are surfing wirelessly from the same router.
    Sometimes these bouts resolve spontaneously. Otherwise I need to shut down, wait, and restart my iMac to reconnect. The longer the shut down, the longer I can connect it seems.
    The problem started a few days ago, after months of trouble-free performance with the same settings. The computer usually stayed up all the time. I hoped in vain today's OSX 10.5.4 and AirPort firmware updates would fix the problem ...
    Post 10pm is the most common problem time, 'tho I'm not sure if that's a function of my iMac's uptime (wireless module is cooking?) or some electronic interference firing up near by. Maybe a virus?
    Known potential sources of interference have been around for months/years: my old wireless 'phone is a 900MHz model, the next door neighbor's satellite antenna's been up for months. The dodgy power in this old building is hopefully offset by the APC UPS that powers my Mac.
    Do I keep fiddling with the AirPort channels, or do I take my computer back to the shop for (another) warranty repair?
    Greg./

    No, I'm not letting my neighbor steal my signal. He's subletting off me, and his access to my network (WPA2 encryption) is part of the "deal". He's a bit of a night-owl, and the late night download limit is pretty big, so it works fine all round.
    I used his laptop's (and my iPod Touch's) uninterrupted access (while my iMac's floundering in packet-loss purgatory) as a way of "narrowing down" to the prime suspect: the iMac wireless module.

    ps sorry about the unnecessary alliteration; I had to substitute "purgatory" because the forum software censors "****" (aich, ee, ell, ell).

  • Setting up a WiFi network from iMac... works on "old" iMac, not "new"

    Hello,
    I hope I'm not crazy, or even worse, stupid.
    I an running two iMacs in my home office. Old one= 21" 2 Ghz PowerPC G5, purchased summer 2005 and still running like a champ.  New one=27" 2.7 Ghz Intel i5. Purchased the new one July 2011. I have a cable modem plugged into the ethernet port on the old iMac. I've been accessing internet on new iMac with wifi and the internet sharing network I set up on old one. I also use wifi on my ipad and laptop. I have never had even a single dropped wifi connection on any of these devices.
    I pretty much expected the same kind of result and performance when I reset the cable modem and plugged it into the new imac and took similiar steps to set up  internet sharing/wifi network on new iMac. This has not been the case.
    What's happening is:
    The cable modem plugged to new iMac is working fine; verified with ISP. I set up wifi network on new iMac and turn on internet sharing. I locate my network name on ipad, laptop, even the old iMac, and I see the name in the list, so I figure so far so good. The signal icon appears in menu bar as usual. I open a web site to verify it's working. And it's working...for about 20 seconds. Then I get alert messages that there is no internet connection.
    After creating a bunch of new networks and changing channels, changing type of security, even passwords, I realized I wasn't going to figure this out by myself. I'm not a technical person; Apple spoiled me and I stopped learning how to do anything except plug stuff in 20 years ago.
    I started researching online including these discussion boards and answers have ranged from "It's the iMac! It's a hardware problem they never fixed! The aluminum case gets too hot!" to, "there's no airport card and you have to buy an external router."  I gave up and called Apple, thinking surely they'd be able to give me a straight answer. Ha ha. Nope.
    Of course the bottom line is I could buy applecare (haven't yet...haven't used the computer hardly and I'm still under warranty), I could buy telephone tech support, or I can take the machine to the geniuses.
    I keep thinking this can't be that complicated. When I buy a new iMac--this is my 4th one--I expect things will get easier, not this complicated mess.
    Oh, last I want to include I just reversed everything back to the way it was. My old iMac is connected to the cable modem and the old iMac is back to being my wifi network, sharing internet with the new imac, my ipad and laptop. Easy as pie.
    I'm making an appointment with the geniuseses but hoping it's just something I'm too dumb to realize I'm doing wrong.
    Thank you in advance for your patience; any help is much appreciated!

    It never occurred to me that the wireless network/internet sharing thing wouldn't work just as well if not better on a brand new machine with the improved technologies I pretty much expect. Metal could be interfering with the signal? The machine is aluminum!! I'm no engineer but that seems kind of...flawed.  I just don't understand.
    I think the WiFi antenna is near an edge of the computer to avoid being encased in metal. It should work like t did in your old computer, but as I said, the use of a Mac to share an internet signal is much less common than use of a router so even if the newer computers have a non-optimal design, it might not get widely noticed in forums like these.
    Sounds like AppleCare is what you want, so I'd get it and then have them check that your Mac is transmitting thru the wireless card/antenna as strongly as it should be. The antenna clearly works as you can RECEIVE a signal, but the transmitter uses different circuitry than the receiver. By the way, I think AppleCare is a good thing to get for iMacs and for laptops as they are very compact and tend to be more prone to thermal problems than other desktop computers.
    I have no idea about routers aside from, of course, the apple air port one that the phone tech support guy mentioned. Are there others that are less money and just as good? I don't feel like rewarding apple for selling me a product that doesn't do what the earlier geration machines did without a problem. Seems like they shouldn't make another $200 because of their flaw. My old iMac's wifi signal was strong enough for a 3500 square foot house, 2 laptops and an iphone.
    Would getting an external router definitely solve my problem? Which one would you recommend if I go that route?
    I also did not understand why the Apple routers (Airport) were so much more expensive than other brands. So I purchased a linksys n router some years ago and it has worked quite well. They are very easy to configure through an ordinary web browser (some Mac folks prefer the Airport utilities that are used to configure the Airport routers, but I find the web browser interface very easy to use for the non-Apple routers), and they are in very widespread use (linksys isn't the only brand that is good for this, there are others, but I've had good experience with both Belkin and Linksys). You can get very high performing n routers from Belkin and Linksys for under $100. I'd get a router that has dual band (2.4 GHz and 5 GHz), and I think most include standard features like MAC filtering (a security measure), WPA2 security, and I thiink offering Gigabit ethernet ports would be good also in case you connect something to it like a hard drive server or a printer or want a fast local network sometime in the future.
    I think the router will solve your problem and do a better job of wirelessly distributing your internet signal, but if the problem is due to a faulty wireless card (that receives fine but doesn't transmit properly) in the new iMac, I'd want to get that fixed under warranty (or AppleCare) now rather than later.
    One more thing: if your wireless card in the new iMac is working properly but the physical layout is such that the internet sharing isn't working well, you OUGHT to be able to eventually get it to work by moving the other devices you are sharing with around to different locations, as eventually one should end up in a spot that works. If nothing can receive the shared internet from the new iMac, even when 3 feet away, then something might well be wrong with the new iMac's transmitter.
