Wifi wireless with iMac

have an iMac airport integrated in my caravan which is aluminum coated.
Neighbour has wifi and for me to use wireless. But receive very low signal.
My idea is to add cable to the outside and ad wifi stick to get better results.
But there are comments that adding second wlan can cause damage to one of the cards.
What is best solution. Can`t go on like it`s now.

I found the same thing, it looks like Apple products only work with 40MHz at 5GHz, but at 2GHz they only connect with 20MHz channel width. This is a shame. I don't know the reason, but most non-apple laptops support 40MHz in 2GHz too.

Slow wifi speeds with imac 3.06ghz

Hello,
So I just got my new imac 3.06ghz with 2gb of ram and I have noticed the internet speed when using wifi is extremely slow. Currently I am using a linksys wrt54G router with time warner cable. If I have my old 1st gen macbook side by side with my imac the macbook shows full signal strength on the airport and the imac shows only a few bars. If I run a speed test with them both the macbook downloads at around 1.5mb and the imac gets a blazing 51k.
Weird symptom on the imac is the blue status bar starts to load in safari, it gets about 3/4 through and then freezes and sits at 3/4 done for a few minutes. During this time images and text on the site slowly start to show up, just like if you were back on a dialup connection.
Troubleshooting that I have done:
reset smc and pram
erase and install
downloaded all available software updates
changed the channel that the router is broadcasting on
- router security is using wep and mixed b&g
- other devices that work fast with a wireless connection on the router are an iphone, xbox 360 and nintendo ds
* even tried testing with win xp and bootcamp but I haven't figured out how to get windows to recognize the wireless card yet
So i'm at the point where I'm assuming this is a hardware issue, maybe the airport antenna?
Any other suggestions?

Everyone on here that is experiencing these wifi issues with their new iMacs NEEDS to call Apple and get this elevated. I'm out of the country right now but I'm in the middle of troubleshooting this issue with Apple. I've spoken with several techs and most don't read this forum and are unaware of any widespread wifi issue with the iMacs. When I return home I will be continuing my troubleshooting with Apple on this issue. My symptoms are very similar to the ones posted in several recent threads on this issue. So far it is pointing to a software problem but I can't rule out the hardware yet. However using BootCamp I can launch Windows Vista on the same machine and surf the internet at high speed through the same Time Capsule. Also all other PC's on my home network are connecting to the Time Capsule at high speed with no hiccups. I didn't notice the problem until all the updates were loaded onto my new iMac which I received July 18th.

Hp laserjet Pro 200 M276nw won't consistently connect wirelessly with iMac

I'm on my second brand new hp laserjet Pro 200 M276nw in 3 days, it will not consistently connect wirelessly with my newly purchased (8days old) Apple refurbished 27" iMac on OSX 10.9, i7 chip & Fusion Drive. The hp laserjet will sometimes connect wirelessly immediately after clicking "print" on the iMac, but about half the time it says "printer not connected" & takes 2-4 minutes (or longer) before the devices do connect. I've called hp support many times, they're reset various things via remote takeover of my iMac, the printer will work for a few of minutes but then the same problem returns. AppleCare made sure I have the
correct Airprint driver installed & also checked my settings, but says they don't know why this is occurring. I've also verified that our newer (6 months old) AT&T router is functioning correctly.
My older hp laserjet (CM1312nfi MFP) has worked flawlessly since 2009 via USB connection with my old iMac (still on Snow Leopard), I assumed it would continue with the new one, but there is no software update for Mavericks & the scanning feature won't operate on the new iMac. Hp says it is a discontinued model. The new hp laserjet is a successor model to the older one, they are both very similar except for the new wireless feature.
I can print fast & wirelessly from the new iMac via a different new hp inkjet printer (8600 series) here in the house. This inkjet printer is less than a month old, I installed it myself for a Windows laptop here, it has never malfunctioned. Unfortunately it's upstairs & I do not like inkjet print quality, I need a good laserjet here in my office downstairs next to my iMac.

HI there
Did you manage to sort this issue out - as I have exactly the same problem.
Lots of similarities as I also have an inkjet 8600 which works via USB and wirelessly no problems at all!
I always buy HP printers as they are usually easy to set up - but this one is making me tear my hair out!
I've even upgraded to Yosemite and downloaded the new drivers from HP - no success. The printer will print one page and then become unavailable.
I can print via USB or wireless direct - but not just via my wireless network which is what I want to do!
No responses posted - so assume no one has a fix.
aaaargh!!!

Printer not connecting wirelessly with iMac

MacBook Pro working on OSX 10.4.11 wirelessly with Epson PX710W. Tried to add iMac on OS X10.5.8 but failure to connect on every attempt after numerous sessions with Epson Support. Have repaired permissions having previously run verification of HD which was reported OK. Reset printer system and reinstalled drivers without success. Still receiving message job stopped on both computers. On setting up the sample page to print, when selecting the PX 710W printer or the other printer option, there is a quick flash. Then the MacBook will not print due to 'communication error'. But if the PX710W is turned off and then on again, the MacBook will print.
Any help would be appreciated.

Switch router to channel 1. Disable and remove all security on the router. Now try to connect to your unsecured SSID. Are you successful?

Wifi issue with iMac running mavericks 10.9.4

I have a 2010 iMac running Mavericks 10.9.4 and am having constant issues connecting with the wifi. If I turn the wifi off and back on I can load 1-2 pages, then it will not load pages, the connection is dropped. The problem is not the router, wifi connection is fine on my macbook running mountain lion and on my iPhone. The settings are correct, it shows that the wifi is connected, PHY mode: 802.11n, Security is WPA2, transmit rate: 117...
Help please...

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 5
Reset the System Management Controller.
Step 6
Reset the PRAM.
Step 7
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 8
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

IPad 2 wifi issues with iMac internet sharing

I have the iPad 2 [ (Wifi + 3G) ( iOS 5.1.1 (9B206) ] which connected to my 21" iMac [Mac OS X Lion 10.7.4 (11E53)] through Internet sharing seemlessly some time back.
However of late, with latest software updates on the iMac & iPad, the connection seems to work only intermittently.
The connection breaks every half or one hour, despite both the devices being in the same room.
I have tried almost all suggestions on forums like resetting your network settings on iPad, changing channels on the iMac for Internet sharing, with or without password security, resetting the firewalls on & off on the iMac, but nothing seems to work & the only way is to reset all your settings all over again.

I used Internet Sharing like this couple of times!
The situation happens is that when you share your internet over Wifi, and you password protect it, when you connect the iPad or any iDevice to that new hotspot, it happens that after selecting that hotspot, we need to turn on "Auto Join". So when the iPad gets disconnected, it gets disconnected completely and you need to connect back once again. So when you turn on "Auto Join" it will get connected automatically once again it gets disconnected maybe due to power saving or suddenly it leaves the hotspot.

Trying to connect wirelessly with IMac G5

I have an IMac G5 which I would like to connect to a wireless network which I have set up with a BT Home Hub. The G5 does not have an airport card, but I have just bought a second hand Airport extreme (old version) base station through e-bay. I am really struggling to set it up. Do I need an Airport card or can I connect it in some other way. Not sure what cables etc etc I need. Many thanks

Thanks but isn't that basically what I've bought from ebay - an Airport Extreme base station, albeit an old one?
Sorry, but no. The AEBS does not support the ProxySTA feature of the newer 802.11n AirPort Express (AX).
Are there any alternatives?
Other than the AX, other vendors, like Linksys, offers Ethernet bridges.
Is it really difficult to set up the proxy link you mention?
To activate ProxySTA, you must set up the Express to join a wireless network and then enable the Allow Ethernet Clients setting; both settings are located in the Wireless tab of AirPort Utility. The feature should work with any wireless network: a, b, g, or n; and 5GHz or 2.4GHz. (Note that the Express, which ships with firmware 7.3, must also be updated to firmware 7.3.1 for this feature to appear.)

Scanner does not work wirelessly with iMac

I have an imac and an HP 8620 (not a cheap printer!!!) trying to scan wirelessly running latest 10.10.2 and all i get is "The operation couldn’t be completed. (com.hp.scanhandler.error error 2.2)" I have uninstalled reinstalled, run the cd and still NOTHING.HP are as much help as a chocolate teapot, just telling me to go round in circles doing what I've already done!!!! AAAAAARRRRRRGGGGGHHHHHHH

Hey ! Thank you for posting on the HP Forums! I would be more then happy to provide some help regarding scanning with your Officejet 8620 to the Mac computer. I find that a great way to scan on the Mac computer is to use the application called Image Capture. Image Capture is a an application built into the Mac operating system that allows you to communicate with the scanner and other image capturing devices. To open Image Capture click on the Spot Light (Magnifying glass icon at the top right corner of the Mac). Type Image Capture into the little search bar and it should show up as the first selection. Open Image Capture and select your printer on the left side of the window. The printer may be listed under "Shared". Once the printer is selected you should have the option to scan. There is also another button to "Show Details". That gives you more options for setting up the scan. You should have the option to name the scan, select a folder, change file type, etc. Here is an Example of Image Capture: Please post back and let me know if that worked for you

Want to print wirelessly with iMac and Cannon Pixma MX870

I have airport turned on. My printer software is loaded on my iMac. Used to print via networking but want to print wirelessly now. Both my iMac and my printer are connected wirelessly to my Bell 2WIRE Gateway interent modem. Internet works fine. Why can't I print? Do I need to purchase Time Capsule or the Airport box to make this happen? Helpless in Stonebridge

You didn't look far enough .... http://www.hp.com/global/us/en/wireless/printer-setup-help.html
The next thing is to look in the manual that accompanied the printer for how to use the wireless setup wizard!
This is specific to your printer ..... http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02217452&lc=en&cc=us&dlc=en &product=5109847#N728

WiFi drops with iMac (late 2012)

I have an iMac 27" late 2012 model. We changed our broadband provider from ADSL to cable. Due to this change, the router (i.e. WLAN AP) is further away than before. The signal is weak with the iMac (-75 dBm / -87 dBm). Worse, every other few minutes, the signal gets lost. This could be accepted if my Retina MacBook Pro, my iPhone or my old iPad 1 showed the same behaviour. Interestingly, those devices work fine at the same location where the iMac is located. - Due to the 27" screen, I would have expected the opposite as the antenna of the iMac is much larger... - I suspect that the Airport Extreme adapter of the iMac is not working properly (using Firmware Broadcom BCM43xx 1.0 (5.106.98.100.22))
Any ideas how I can get a stable network connection?

Which version of OS X?
Try making a new network location as shown under the heading 'Making new locations' in this link:
http://support.apple.com/kb/HT5289
Try the 'fixes' suggested in this link which seem to help some, but not all, users with Lion or Mountain Lion installed. Also check the links within the article:

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,etc

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,switch channel from auto to maybe 6,channel width to 20mhz? Already changed security settings to WPA2. Currently router is running in mixed b and g mode.

If you have one computer running on G they will all run on G. All ROUTERS are backward compatible, in otherwords if you have a group of computers and all of them are N compatible and one or two are G They will all work but the N computers will run at N and those that are G will run at G speed not N.
It can get confusing but really it is simple. The newest is 802.11 AC and ic used with the newest Mac Computers made available in November 2013. So if you have the newest Airport Extreme that is 802.11ac and the newest computers that are AC compliant your speed will be 5 times faster than anything on the market right now.

Problem connecting wirelessly from iMac to NETGEAR router, get invalid password message with WPA and WPA-2 encryption in place but if I remove them, so no security, can connect without a problem. Help!!

Problem connecting wirelessly from iMac to NETGEAR router, get invalid password message with WPA and WPA-2 encryption in place but if I remove them, so no security, can connect without a problem. Help!!

Thank you for your suggestion but I have already had a couple of phone sessions with NETGEAR support and they don't see any problems with the router settings etc. They referred me to Apple support, who helped me discover that it is possible to communicate with the router but only if I turn off the encryption/security software, which I don't want to do. The frustrating thing is that I can connect wirelessly from a laptop running Windows 7 and two Anroid smart phones, with WPA-2 in place, without a problem. Do you have any other ideas?

Bug in wifi/wireless connection with captive portal in UK/London ?

With my macbook pro (10.6.4) & iphone (iOS 4), I do not manage to have an easy connect on free wifi captive portals in London. They all are new connections (unknown networks before).
* dhcpd lease seems to be instable. I can get wifi connection (with good wifi signal strength) but most of the time get a "non-allocated" lease like 169.254.57.x/24 without any router/dns. A few rare times, the dhcp server give a me a complete ip connection.
* in the rare case where IP connection could established, I was not redirected to the captive portal. I had to manually enter its address (in my case <IP>:8000, you need to guess) and even after authentication, I can't browse the Internet. In one of my test, I managed to resolve dns entry but can't browse the web.
I tried during an hour and I couldn't make it on work on my Macbook. work a small time with the iPhone.
tested in McDo free wifi and Airbox Public Wifi of EasyHotel (Airbox system). also have problem with "Wifi Zone - The Cloud".
ok in Starbucks and in St Pancras Free Wifi.
Found these threads which could be related but no real solutions:
http://discussions.apple.com/thread.jspa?messageID=11875166&#11875166
This is probably the router's fault but I can't check this.

Hmm...pretty interesting. What redirection mode did you use for m0n0wall? (http or dns) Have you tried disabling the NAT on the router as well as unchecking the block anonymous internet requests on the security tab?
I have a similar setup on a T1----media converter----WRT54G setup. Basically, the router was able to get public wan ip addresses on the status page. So do the computers behind it (wired and wireless) but they aren't online. We pinged the three dns numbers on the router, only 1 replied. Now, the ISP has Cisco all-access installed on the converter (quite similar to captive portal) and it shows up on every computer when we try to go online. We open up the browser, it prompts for the authentication. We fill-in the details but still it doesn't go online. Bottom line was we cloned the mac of the main computer and they didn't need to authenticate...but then again it defeats the purpose of the software.
Also, the router was set as a DHCP server with NAT enabled. I'm thinking that the router's firewall still blocks your computers even when it's already set as a switch. Try to disable the NAT and see if it works.

Hello:
There was an OS X 10.7 update released a month or so ago that fixed this problem. Run software update.
