The internal cards are said to have a comparably weak reception, cost much more and if you're unlucky the Antenna is not present in the computer as it should (can e.g. Happen on refurb machines). Sometimes you can use the cheapest PC USB stick, even if it offers no OSX support officially. The AirPort Extreme Card for Mac Pro (Early 2009 'Nehalem') from Apple adds 802.11n Airport Extreme Wi-Fi to Mac Pro computers with Nehalem processors. It installs in the Airport Extreme slot in the Mac Pro.
For a Mac Pro the easier method is to use ethernet to a wireless bridge. As an example this is totally simple if you already have an Apple airport as main router. Just buy another one. And plug it into the Mac by ethernet and setup wireless extend. Unfortunately Apple routers are not as flexible so if your main router is not apple, then only the express will do this job.
And it is somewhat slower than latest AC wireless. About 5x slower.
But there are plenty of other brands that will work fine. The big advantage of following this path is no need for drivers. USB wifi are available but tend to be poorer and I would not use them. A Mac Pro has extra slots which means you can buy an Internal wireless card as replacement. These are fairly cheap if you buy one that is Mac compatible.

PCI Express expansion. Three open full-length PCI Express expansion slots 5. One PCI Express 2.0 x16 slot. Two PCI Express 2.0 x4 slots. All slots provide mechanical support for 16-lane cards So if you want an N wireless card which would match the existing one. You can buy a fairly cheap TP-Link card.
Which are about $35US so cheap. You can buy other AC standard cards as well. TP-Link ones. T8E or T9E which are substantially more expensive.
Almost I have to say a cheap AC wireless bridge would be cheaper and less hassle. Or you can hunt down a replacement wireless card. Although I am not at all sure the current one is actually broken. Sierra has more wireless driver issues than most. Did you upgrade this computer? Was the wireless working before the upgrade? I would do a search for wireless card failures with Sierra.
They happen alot. In order to check if the card has really failed run the hardware test for your Mac. Thanks so much for your reply. I was having issues before I upgraded to Sierra. It's why I upgraded, hoping it would solve the problem. I don't have an apple as my main router, I have a TP link.
Don't understand buying another one and using Ethernet connection. I would have a huge router connected to my computer? As for buying another card that means I would have to open up the computer and find where it goes? The thought of that freaks me out. I will google 'wireless bridge' and do the hardware test.
Have just returned home after 3 months in Mexico so am just catching up on alot and feeling swamped. I would have a huge router connected to my computer? Your computer is huge. As long as we are talking Mac Pro the relative size of the router cf the Mac Pro would be about 20:1 in volume. Don't understand buying another one and using Ethernet connection. Let me spell this out because this is your best solution.
As my main router, I have a TP link That is excellent actually. Apple to Apple, TP-Link to TP-Link. It will work much the same.
Most of the TP-Link routers support WDS (this is similar to system apple uses to extend wireless) Please tell me which model router you own. If it is a pure router without a modem there is a good chance buying a second one will be able to do wireless bridge for you. I will check that if you give me the model. The method is easy to understand. At the moment you have a main router. And inside each computer and device is a wireless client card which creates a link. Now using a wireless bridge simply moves that link from inside the computer to outside.
Instead of the wireless client being plugged inside the computer it is plugged outside by ethernet. The cable is say standard patch cable 2M (6ft) long. You plug the wireless router into power and set it up as the wireless client for the computer. See typical WDS instructions from TP-Link If you find other brands hard to work with then buy the Apple Express. It can also do wireless client mode. Apple have instructions for the setup. IMHO using identical devices in WDS is superior.
But Apple do make the setup of the Express easy for Mac owners to understand. There is another solution. Which you might find even easier.
Forget wireless completely and use Powerline adapters. These are not always going to work. Just as with wireless if the house design is difficult they work poorly or not at all. But for lots of people they work really well.
You plug one in next to your existing router. And plug the other end in next to your computer and plug ethernet patch cord into that.
Set it up which is no more complicated than pressing buttons on the unit. TP-Link also make lots of versions of these. Easily buy AV500 set for under $100US and the much faster gigabit versions for a bit more. When they do work, they are faster and give more stable connection than wireless. Your computer is huge.
As long as we are talking Mac Pro the relative size of the router cf the Mac Pro would be about 20:1 in volume I have a mac book pro laptop, 13'. I can and am using an ethernet cable at home. What I'm looking for is a way to be un-tethered. So I can take my laptop without any cords and have internet. Not trying to extend my range. Want to be able to take my laptop anywhere and everywhere and have wifi.
Not just in my house. Sorry if I haven't been clear. Just have no traveling wifi and want the easiest, cheapest solution. Thanks for answering. Your list of equipment and first post said Mac Pro. Which is of course the one I thought you were talking about.
Macbook pro is totally different. If the laptop is failing to enter hardware test.
On a 2010 model you should be able to boot from your original DVD. In fact this is the method. The OS referred to is the original OS. Which would have been 10.5 Leopard or perhaps 10.6 Snow Leopard. If you're using OS X Lion v10.7 or earlier and you can't get AHT to start, see if you have an OS X installation disc named “Applications Install Disc 2.” Insert the disc in your internal optical drive or external Apple SuperDrive before following the steps above.
Or, if you're using a MacBook Air (Late 2010), plug the MacBook Air Software Reinstall thumb drive into your USB port instead. If you want mobility it might really be better to purchase a new laptop if the current one is broken. You can buy USB compatible sticks. They are not a great option though. You can also get a replacement wireless card but if the laptop is faulty that will be a waste of money. The laptop itself may need other repairs.
And the card needs to be fitted by expert as there is no convenient hatch like PC laptops for the wireless. Apple Footer. This site contains user submitted content, comments and opinions and is for informational purposes only.

Click to expand.The only problem with this printer is that I don't think its a postscript printer. I have a Brother HL-1435 which is basically the same thing as the Brother HL-1440 that the link goes to. Some of the differences are that the 1435 has a black and silver case instead of a beige one. Also, the 1435 comes with 4MB of RAM (non upgradable), but if you're only doing normal printing then you have no need for more than 4MB of RAM. Yes, there are drivers for Windows 95-XP and Mac OS 8.6-OS X.3.
You can buy an ethernet adapter for it. Its basically an adapter that plugs into the parallel port with an ethernet port on the end of it. Its an awesome printer with excellent print quality and fast. And the toner cartridges are cheap for it too. $50 to $60 at most stores. My only complaint is that when you first turn it on and everything is warming up it dims the lights and makes my BackUPS kick in to provide the power the computer needs. (A BackUPS provides the correct amount of continuous power to you computer) Here is the link to the Brother HL-1435 printer like I have.
