Question: New Macbook Air - wifi connectivity problems

Hey guys,


Hope someone can help?


I have a brand new Macbook Air which is able to connect to the internet for just a minute or two before suddenly it drops out. This is even though the signal still shows at full strength and all my other devices are still able to surf the net as per normal.


This device is straight out of the box so no 3rd party applications have been installed. I heard that the wifi has been upgraded to 802.11n on this machine, could that be an issue?


Do i need to return the machine or is there is a software fix for this problem?


Thanks heaps!


Vicky

MacBook Air, iOS 6.1.4

Answer:
Answer:

Have you cheked if your Netgear router has the latest firmware ? What model number is it ? Your RSSI,Noise, Tx rate etc. look good. One thing you could try is switch to a different channel, say channel 6 and give that a shot.


Can you copy paste info. from your /var/log/system.log info around the time frame you see the drop ? I can take a look and see if it helps any.

I'm having the same problem. Just got my new 2013 Haswell MacBook Air and it won't say connected to the wifi. It will connect at first but then the connection drops. The laptop will refuse to connect again until I reboot the machine. After the reboot, wifi will work again for a bit then drop again. The router is working fine as my other devices iPhone, couple desktops, have no problem staying connected. Router is a Netgear WNDR3700 running the latest firmware version.

This is happening now at least every 15-30 minutes. Again, according to the network preferences I'm connected, but I can't resolve any address. I can disconnect the wireless and reconnect and then the internet works again, but only for a limited period of time. Again, EVERY other device on the network is working fine. Apple where are you?

I have the same problem with my 2013 MacBook Air 11 inches. Something I never had with my iPad, MacBook, iPod or iPhone. The connection drops and the MacBook fails to recognize the signal even close-up. Restart is the only way around it. It does happen once or twice a day.

What wireless router are you using ? And can you connect to any other wireless network or is this specific to just one network ?


Launch Wireless Diagnostics ( Option click on WiFi Menu Extra and you will see this at the bottom) and under Window->Utilities in the menu item, go to the Performance Section. What do you see there for Quality,RSSI,Noise,TX Rate,Channel ? Paste that info. here and I can try to help.

Airport Extreme is my router. In general no problem at all with this the network for this MacBook or any of my other of my Apples. I have only one network here. The breakdown only happens occasionaly and I don't see myself sitting somewhere else for hours to see if it fails or not.

I am not sure where to find Wireless Diagnostics as you suggested. Looked under system preferences > network. Could you tell me where to find it? Thanks fo trying to help.

By the way, I want to add for everyone reading this: it is a grand little machine. The fastest kid on the block. 🙂 Buy it.

Hey wifiguru,


This is the info i get from diagnostics:


RSSI: -42 dbm

Quality: Excellent

Noise: -86 dbm

Tx Rate: 48 Mbps

Channel: 2


The wireless router that i'm using is a Netgear 54mbps Wireless ASDL2.


Unfortunutatly i'm not sure when i'll get a chance to test it on another wifi network though. Maybe on Sunday.


Thank you so much!


Vicky

Hello Guru! This time when the connection failed I did find and launch diagnostics as you showed me to do. Thanks. The message is: "Turn on Wi-Fi, join a network, and then choose "Continue" to run diagnostics." And that is just what I can't do: switch on the Wi-Fi. Restarted and everything is back to normal. Any other suggestions?


Note: The Wi-Fi does not fail when I am on the net.

Also having this issue on a brand new Macbook Air 13", changing the channel has not seemed to do anything. I am using an Asus RT-N16 with DD-WRT firmware. When it happens, every other computer or iOS device on the network is fine (including a 2007 Macbook Pro, a 2011 Macbook Pro, iPad Mini, iPhone 4S). Seems to be isolated to the new Macbook Air.

I am in the exact same boat. I just bought a 2013 13" i7 Air and it connects to my wifi no problem, and it never appears to disconnect but it stops communicating. I disable wifi and enable it, and it is working again.


I am running a Linksys 1100 with DD-WRT, and I have no issues with any other machines, including 2 AppleTVs, an iPad, 2x iPhone 4S, 2 Nest thermostats, 3 Windows laptops and a MacBook Pro.
