Potentially a rambling post while I catalog the issues I’ve been having with my home wifi network today. But always good to store it somewhere.
If I think about it we have, hmm, thirteen devices in this house that connect to the Internet. That includes the iMac, Macbooks, iPads, Phones, Apple TV, a couple of consoles and a work notebook. Wireless coverage around the whole apartment comes from an Airport Extreme connected to the cable router. An Airport Express is at the ‘back’ of the apartment set to extend mode which gives me total coverage.
The other day I upgraded both Airport devices to the latest firmware 7.6.1 and everything seemed to work fine. About midday today my work notebook lost wireless connection. Not a rare occurance using private VPN’s etc to connect to the network. But then it refused to reconnect. I don’t enjoy using Windows systems as the entropy of running it for a while without a restart seems to be pretty quick and I had a lot of documents open. But restart I did as I needed to get a document somebody was sending me. On restart the notebook saw my home network, but refused to join it. Couldn’t repair the connection or anything.
Luckily I run Aiport Utility on all the iOS devices so grabbed the nearest one to check for issues – nothing. The most annoying thing was the iMac which sits next to the work notebook continued to stream Internet Radio,
Nevertheless I restarted the Airport Express to see if that would resolve the issue
No luck whatsoever. Still couldn’t get the Work notebook to join my home connection. It could see it but gave a vague message that it couldn’t join. Tried to repair any problem it had with it’s wireless card but it gave me a suggestion that I could try to troubleshoot the access point. The same access point that TWELVE other devices could quite happily connect to.
I made a few changes to the Aiport configs – such as ensuring theu both assiigned channels automatically and they both were connecting to WPA/WPA2 Personal (as the Express was reporting only WPA2 Personal).
Still no bloody luck. The I tried restarting both of the Aiport devices – everything could connect except the work notebook … and now my iPhone 4 couldn’t connect to the Express either! Argh no steps forward and two steps back.
I would understand a little if I had just upgraded the firmware and it immediately had problems, but I’d been running on the new firmware happily for at least 36 hours.
I tried to do some troubleshooting and searching – with the work notebook and the iPhone 4 both down I figured it must be something to do with the Radio Mode. Both the work notebook and iPhone would have problems connecting to an n network which is why I was broadcasting g as well, and at 2.5GHz and not just 5GHz.
But the whole network was still set to Automatic mode and I should still be broadcasting n and g. Super frsutrating! In the end I reset both the Extreme and Express and set-up the network again. But exactly the same problem. Everything can connect – except the iPhone and work notebook to the Express. Taking a break for a cup of coffee I brought my iPhone with me and noticed it had no problems connecting to the Extreme in the living room. Dammit, it was definitely the Express then.
Tonight I decided to go a bit for a long shot and downgraded the Express to firmware version 7.5.2 (pre 7.6 release) and the iPhone connected with no problems pretty much straight away. UPDATE; Shite it is still not connecting now or even showing the network being broadcast from the Express. The work notebook? Despite running happily on the network this morning with no changes? Still can’t connect so I have it connected to the Express via Ethernet cable and it swims happily on the network then.
So, conclusions and possible next steps for investigation:
- 7.6.x is an issue from a firmware point of view for the Aiport Express
- The devices that can quite happily connect to an ‘n’ network have no issues whatsoever
- My iPhone 4 cannot connect to 7.5.2 on the Express
- My work notebook cannot connect to 7.5.2 either now
- My work notebook can connect happily to the Express via ethernet on 7.6.1 and 7.5.2
- Maybe I need to investigate the DHCP settings of the network?
- Maybe I need to wait for another sodding point release for Aiport as 7.6.x is a nightmare right now?
- Maybe I need to buy another bloody Extreme for the back of the house as the Express is the issue?
- Maybe I need to get requisition a long overdue new notebook from work?
- Maybe I need to find a job where I can use a sodding Mac!
Well, Netflix is happily streaming on the iMac and wherever I go with the iPad in the apartment – so I give up for tonight.
Will update this post later if I ever get a solution.
UPDATE: Well fuckity bollox that has only taken about ten hours to figure out from researching and it seems to be only one option change that means every device is connected happily (will try work notebook tomorrow as no way I’m logging into that now to get caught in emails)
Both the Airport Extreme and Airport Express are on Firmware version 7.6 now. I have a feeling this is not the solution but I’m going to leave it until the weekend to test that.
If you hold the alt key and then click on the wifi icon on the iMac/Macbook toolbar you can see more information regarding the local networks. By doing this I could see that my hone network was not broadcasting on 2.5GHz – only 5GHz which would give the work notebook and iPhone issues
I left the Radio Mode setting as 802.11a/n – 802.11b/g/n (automatic)
I left the 5GHz Channel as Automatic
I changed the 2.4GHz Channel to Manual and selected 7 (seems everyone in the area is broadcasting on 1)
VOILA! Everything is happy to connect to the Network with no strange issues. I’ll test this on the 7.6.1 firmware at the weekend. Lesson? Don’t trust Automatic Channel selection too much – especially with a lot of wifi in the area.
