I have Macbook Air problem with its WiFi, its very slow what could be the problem? Bad wireless card
Anna - Check your systems & AP setup. I think you got your self caught in the 5 GHz problem 802.11ac range issues: Overcoming wireless signal shortcomings. Different frequencies have better distance and can get though walls better. 5 GHz is great for data throughput but it can’t reach as far or get though walls that effectively. What I do is setup the different bands of my WiFi router with slightly different names (I add 2 & 5 at the end of the name per the frequency). Now try this: Your older MacBook is accessing the 2.4 GHz band with its older radio. Now alter your settings in the Air so it to is accessing the same 2.4 GHz band. You should now see the same performance numbers! From the same location in your house. Also don’t forget the 802.11ac based Air systems don’t have MIMO (two matched antenna’s) So you won’t get the full ability unlike the newer MacBook Pro’s can which have MIMO with 802.11ac. Even still MIMO services are limited to a single system at a given time. This is where the newer multiple flow feature that many Router companies just intro’d in Los Vegas CES show MU-MIMO this last week will give you the real bang in performance if you have a local server or very good access to the internet with multiple systems fighting for access over your WiFi network. FYI: Most of the US has very poor data rates though there ISP. Even still the resource at the other end may still throttle you. So it will be still awhile before we get then needed data flows to really benefit with these faster local connections to the internet.
Was it always this way or did you recently upgrade to Mavericks or Yosemite (lots of known wireless issues with those OS builds). Further slow network issues can sometimes be: an ISP issue, grabbing onto someone else’s new open home network, a new home network running on the same channel as yours. P2P sharing (iTunes music, iPhotos, doing cloud backups, streaming video to a TV) can also slow a network.“Freeware” phoning home Try checking the network ID your using, try chaining your wireless setup. If this answer is acceptable please remember to return and mark it accepted.
Apple knows this is a issue and they want to blame everyones wif. I have a macbook pro build 2011 and it is 3 times faster than my new macbook air on wif.
I am in the same boat; it’s apparently a common issue. My iPhone connects to the wifi just fine. My coworker’s older MB connects just fine. It is only my 2013 MB Air. http://www.engadget.com/2014/01/21/2013-…
my 2015 mbp is hopeless on my home wifi network. they want you to spend more money on their products to get the full use out of your products that you’ve already spent a VERY pretty penny on. fek the greedy kents. apple, what a joke.
get a new macbook stupid Update (03/27/2020) your macbook is bad so get a macbook pro
For me, I found out (after trying just about everything I could find on the topic on the Internet) that the problem was with Bluetooth and namely a Microsoft Bluetooth Mouse. As soon as I removed/Unpaired it on Bluetooth Preferences the Wi-Fi speed came back and web pages loaded fast again. Re-adding the Bluetooth mouse and everything went to a crawl again, remove it again and everything speeded up. I did not have to restart Safari or the MacBook, although I did shut down and start up the MacBook again just to make sure it still worked and was not a fluke
