7.7.9 Firmware update reduced range of Airport Extreme

I had the same problem. I turned off file sharing in the AE settings, updated the AE, and then turned file sharing back on. Stable so far. Possible hung/runaway process issue with file sharing/USB external drive controller.

Thank you that’s OK

Thanks, that's right.

In fact, i downgrade to 7.7.8 and still have the issue after few hours. I found something: i moved from flat and in the new one, my ethernet wiring topology is not the same. Before, my IPTV ISP box was directly plugged on my ISP router/switch. In my new flat, as all rooms are wired with RJ45/Grade3 cable, my AirPort is wired on the router and the IPTV box is plugged on the Airport. I tried to enable the IGMP Snooping, but there is no difference, after few ours of delivering flows, the Airport is not able to authenticate any Wifi packet, password is ask on MacBook, iPhone....immediately, if i unplug the IPTV Box, wifi can connect, maybe the memory consumption of the Airport to manage IGMP trafic is to high, i don't think it's a CPU issue because the fan stay silent (i hear it at high RPM with 7.7.9 during factory reset, it's impressive).

We have pretty agressive IPTV flow here in France when using FTTH connection, 20Mb/s per flow, it's agressive in terms of packet/per/second and many people wants to use an aftermarket Switch or router have issues with IGMP/Multicast trafic, so no reason there is not with Airport.

I have no possibility to connect the IPTV box directly to ISP router anymore as i have only one RJ45 plug in my room, i have to find a solution.

Sorry for my poor English, i hope you will understand the story 😉

Activation of IGMP snooping has resolved my issue by activating the Multicast trafic only on the IPTV port, but there is now some lag every 3/4 minutes, image of IPTV freeze for 2/4 seconds...

I'm gonna change this router, too old i think....

Hello, firmware 7.7.9 have an issue with wifi password

Suddenly my iPhone is showing wrong password when using correct wifi password !

When i restart the router it is ok and password excepted again.

This is very annoying what can be done ?

I can not restart my router every day.

I used this router for the last year without any single issue !!!

Please help !!!

David

Same behavior on mine, but as i explain, it's due tu IPTV box connected behind the Airport, it can't handle the multicast trafic on all ports and serve the wifi simultaneously. The IGMP should help but when it works...

Do you have any IPTV device connected on the Airport (ethernet)?

Dear Friend

Yes , I have an IPTV box connected to one of the LAN ethernet ports in the AirPort box.

I did not have this issue with 7.7.8 version , is it related only to latest 7.7.9 firmware version ?

Do I need to connect the IPTV box to my Main LAN switch ( or local LAN switch ) ?

David.

Yes, i think, if possible, you must connect it on the ISP router directly. Activation of IGMP can also resolve the issue, but , depending you IPTV box manufacturer, you may encounter some freeze. It's easy to test, on Airport Extreme settings, go to Network tab, network options, and enable IGMP Snooping.

Hi,

I connect new 8 ports giga switch and disconnect all AirPort lan ports ( other connected directly to the giga lan switch ) and till now all fine and have no issues as before.

I wander if apple is going to fix this or need to enable the IGMP snooping mode and check if works ?

I do not want to have another box ...

David

It's far more likely that the update prompted a reboot, and as a result, the station had to find a new channel to broadcast under. It's also likely that whatever it found wasn't as ideal as the last. When you are in a crowded area, and a wifi router reboots, it often causes a number of wifi routers to reboot and shuffle their broadcast channels while they attempt to find a 'new' best channel.

It's often a good idea to simply unplug the router for 5 mins or so to allow the others to shuffle and latch on to their channels and then bring the airport back online. It will then have a good look at what's currently in use instead of seeing a lot of routers rebooting and picking a potentially bad channel.

I just got off the phone with apple senior tech. I mentioned to them that the forum is actually more helpful right now on this issue as they are escalating my case to the engineer level. I did go back to the previous version 7.7.8 and it fixed my issue with the dropping out of wifi signal. Apple had me upload the log files so I believe that they are getting on this.

Hi

I have the same problem and it's really boring. All my alarms and video cam were connected to this Airport, and I had a lot of notification of déconnexion. Now, I know where it's come from. Hope Apple will fix it. I had bough Orbi instead for my alarm and cam working fine.

I just downgraded to 7.7.8 to see if it's better.

Thanks for your response in this forum because there is no communication from Apple.

Probably you have fixed the issue by now, but since I didn't see it posted here, I would like to share a similar experience I had and fixed.

After an update, most of my devices stopped being able to see my 5GHz network, trial and error method helped me discover that those updates reset the channels to "Automatic" and that for some reason the channels in themiddle were invisible to my 2013 Macbook Pro and My Thinkpad, along my Chromecast. Moved to the lower-most channel (62 if I recall correctly, not in the mood to confirm) and the 5Ghz network was back in sight, working as usual. You can try this and let us know if it worked or if the issue persists.
