    Hi all,

     

    Same problem here. Wifi worked fine but the last two months it is a little disaster. Wifi drops several times per hour only on my iMac. Renew DHCP lease is the workaround. Had the problem with previous ADSL provider and modem and it continues with my new ADSL provider with another modem. My daugther with a MacBook has no problems, iPhone's, iPads work fine. Only my iMac from 2011 has the problem but why? Running Moutain-Lion with all the updates.

     

    Dear Apple please provided an solution because like this I almost start to think that W8 is back a beter solution. Can't image that I wrote that!!!! Have Wifi diagnostic run so if needed I can provide more details.

    Working WiFi would be a great thing!  What do you see in the wifi.log as the disconnect reason? Also, if you open the console and select All Messages, do you see anything interesting scrolling by there?  Discovering the disconnect reason will really make it easier to understand where the fault lies, and then getting that fixed.

    Hi gphonei, Thanks for your feedback. Did a quick scan of the logfiles but nothing found but do not exactly what to look for. But I think I have the solution found. I saw an article about wifi b/g and n. When forcing wifi to use only b/g the problem disapperared. So it can be somebody around my house but I already changed the channels several times or a bug in OSX 10.8. With the last fixes in OSX I found OSX suspicious. We will see what the next release will contain. Bye.

    This solution worked, until it dropped again. I was really hoping it would have worked it seemed promising.

     

    I am not sure what's going on with this wifi but I never had problems with my 2008 Macbook pro 15' running on Leopard and Snow Leopard. My 2012 Macbook Pro 13' running Lion 10.8.2 is just having issues with holding a connection.

     

    Its been dropping like crazy but the solution that I tried made it stop dropping like crazy today. It dropped once after so Im not convinced that Billjacobson's solution works.

     

    All I can say is from reading what a lot of the posters here are saying, it really does seem like a software/driver issue with the Wifi.

    It made my wifi drop less but it was still dropping

    Turns out this didn't fix the problem for me after all. What actually did it was setting up a static IP and making it require a password to change/disconnect from the airport. I had to totally manual settings not just DHCP with manual. The MTU wasn't the issue after all.  So far so good but last time I said that my connection dropped hours later so who knows.

    I believe this has something to do with Bonjour Sleep Proxy (Wake on Demand) interaction with router that is not 802.11n.  The "n" suffix is the problem; a lot of routers are "g" suffixed.  Routers must have firmware that includes the Bonjour Sleep Proxy Protocol- new apple routers do;  but not necessarily other manufacturers' devices.  To make this even more complicated, even if you have hardwired ethernet network, if you have older devices, printers, apple TV, you will get the same problem.  For Wake on Demand to work, ALL devices in network must have Bonjour Sleep Proxy Protocol installed

     

    Steve bless his soul, pushed the envelope too far, making apple "forward obsolete" from Snow Leopard onwards.  IN the process, apple ****** off Adobe, and god knows who else.

     

    This is just my opinion.  I am going to try turning off "Wake for Network Access" in the energy saving settings.  This will hopefully bring me back to "leopard" which didn't have this problem.  The other way around it is to change energy saving settings to "never sleep".

    Not sure if this would help but I read on other forums through apple.com that it could be an issue with the router. I know that everyone else is not having problems with their routers with other computers but D-Link has said that they had compatibility issues with Lion specifically. They were looking into a fix for it. Not sure if they have I hadn't done enough research yet.

     

    It could depend on your Router and its firmware update. Best thing to do is to call the company's support for the router and ask if there have been any issues with Lion and their product and if they are working on a fix.

     

    My Issues are at work on a D-Link router. I will look into upgrading the firmware once I figure out the password to see if that helps.

     

    I have a Linksys at home and I don't have any issues with that one. I haven't had the wifi drop on it yet. I will keep on eye on it tonight though to see if it does drop.

     

    If you are having issues it would probably help to post what router you have and which version you have on your firmware. Here are mine at work:

     

    D-Link

    Product: DIR-655

    Hardware Version: B1

    Firmware Version: 2.00NA

    The wake on LAN stuff in unrelated to bonjour.  It is an industry standard designed to facilitate remote admin and out of hours operations including backups.  Most likely you are experiencing a problem with old firmware and/or compatibility with standards.  Most routers older than a couple of years have issues with 802.11n because they implemented the proposed standard to get to market faster.  There should be updates, and if your router has not had updates in more than a year, it may be time to replace it with something more current with standards.  Note that 802.11ac is coming like a freight train to stores and devices near you, and there will be a whole new round of this...

    Actually, "wake on lan" is somewhat related to Bonjour when the two are combined to form the Bonjour Sleep Proxy feature.

     

    http://en.wikipedia.org/wiki/Bonjour_Sleep_Proxy

     

    However, I agree that it's unlikely this is causing failures to join Wi-Fi networks.  Although it would be interesting to turn off "Wake for network access" and see if that fixes anything.

    Speaking figuratively.   All of these problems with wifi dropping seem to have begun with Snow Leopard.  Coincidentally this is the OS that incorporated Bonjour Sleep Proxy.  I think that only works with newer routers.  I don't appreciate that upgrading to Snow Leopard requires me to buy a new router

    Thanks for the pointer on this.  I had not seen this as a point of interest, but clearly, this is probably "the feature" which stimulated the "won't reconnect on wake" issue.  It would be interesting for those still experiencing problems with their routers to see if turning this feature off helps.  I wonder if Apple turns it on when they sense support for it from the router, or if it is just on by default.

    I never had a problem with Snow Leopard dropping wifi. I had a 2008 macbook pro with both Leopard and Snow Leopard connecting wirelessly to my work router and I never had problems.

     

    It wasn't until I got a new Macbook Pro with Lion installed that I started having wifi issues. But I only have wifi issues at work. Lion works fine with my Linksys router at home.

     

    I am pretty convinced that it has to do with the router. At least for me it is. I checked the firmware version of my work router and it is still at the factory version. There have been at least 3 updates that have happened and we haven't updated the router yet. Once I get that all figured out, hopefully today, I will update my progress.

    I think you are going after the right problem.  Wireless routers are complete computers, and having the correct software in them is a necessity, and a responsibility of the owner at this point.  I bet you will see better behavior after the update, but there could still be problems.
