    The problem started after the latest update - and the problem is WEP

     

    Setting up a computer to computer network - internet sharing apple either uses none, 40 bit or 128 bit WEP

     

    But since the update the 40 bit broadcasts as 64bit so nothing can connect.

     

    I do not agree that switching of security is a solution - it is a temporary patch

     

    this is coming up for 3 years or Apple WiFi problems

     

    A solution would be native WPA - or even working WEP - but switching off security is an unsecure patch - I am shocked that Apple would suggest otherwise

    After I bought my imac earlier in the year with Lion installed I too had problems with connection after sleep. Tried Applecare with no success (a load of faffing around with settings etc).

     

    I then noticed that you should have the up to date firmware on your router (as eshghoolak noted). I checked with my isp provider (plusnet) and for the princely sum of £5 p&p they sent me a new up to date router. Hey presto no problems since then which was about 5 months ago. I can understand frustration for laptop owners in internet cafes etc, but as for a desktop Please Please check the firmware.

     

    As for all these complicated mind blowing PC like adjustments to peoples routers etc forget it get the up-to-date firmware instead.

     

    A side issue I had was the imac freezing after a day or so if left on. Tried Applecare, once again no success. So I took it in to my local Apple Store (even though I had not bought it there) and they fixed the problem. Top Marks for the Apple Store (as noted in Which?).

    Well I thought I had my problem solved but there's been a week since it came back. Now I have this question since I'm no computer expert. My IMac is placed next to my cable modem and I have it working wifi through my airportexpress router so I can also use the wireless network with my smart phone and apple tv. My question is: since the problem is only with Imac, if it is possible for me to wire my Imac and at the same time have another ethernet cable wired to airport express(my modem only have one ethernet port out). That way I solve the problem for me. I was thinking if this device coul help.

    sorry for my lack of knowledge but really would appreciate your help.

    the device u mention is caled a switch and u can then hardwrire your mac to your switch to your modem and turn off wireless

     

    then that will stop any stupid wireless issues

    Thank you kulyk for your answer. Then as I understand the answer is yes it will work, but since I need my airport express to work for my ipod and apple tv would the switch also work to hardwire conect airport express so I can have both connections wireless (ipod, apple tv) and hardwire (Imac)

     

    thanks again.

    i woudl connect your ipod directly to your mac

     

    here are some notes on appletv connected via ethernet

     

    http://www.tuaw.com/2012/04/24/how-to-get-airplay-working-when-apple-tv-is-hooke d-up-via-ethern/

     

    should all be good to go

     

    i would advise u to buy a better swtich with gigabit support since yur mac has it and they aren't much more money

    and it will be more useful for future use too

     

    here is a dlink (which i prefer- theuy have good suppor) just after a quck search

    I haven't had any issues since I posted this and changed all the settings. In fact, before my speedtest always had minimum (maybe barely 10 Mbps) upload/download speeds and now I get over 20 Mbps. My range is is pretty decent too. My router and modem is under a tv stand in the living room and I can get strong signals even at the parking garage 10 -15 feet away.

     

    I did confirm the issue with several people at Apple, Comcast, and with Netgear. Any new Lion/Mountain Lion software update 10.7.4 or 10.7.5 will have issues with the Netgear router and you must update the Firmware on the router to get it to work. You also have to delete memory on the computer of the router (Step 5) and restart everything. It's been 3 full days and I don't have any complaints!

    Thanks for the update!  This is a good example of how everything has to meet standards for things to work reliably.  The fact that Netgear has updated the firmware and everyone agrees that you need to update is good reinforcement of your experience.

    Hugo, which model of the Airport Express do you have?  Do you have one with a single Ethernet/CAT-5 connector, or the newest one with both a WAN and a LAN Ethernet/CAT-5 connector?

     

    The old single port version will not work as you need, because you need the "LAN" plugged into your iMAC.

     

    The newer version will work, because it has a LAN and and WAN port.  You can plug the WAN port into your ISPs modem, and the LAN port into your iMAC and the wireless will still be there for your other devices.

    The old Airport Express only had a one port, that could either be a WAN port (Create a wireless network setup), or as a LAN port (extend or join a wireless network setup).

     

    The new Airport Express has both a WAN and a LAN port.

    why do u need your AE for work if u connect your imac via e-net cable?

     

    and why can't u connect your ipod via cable to imac?  as i mentioned earlier?

     

    just get rid of wireless and go via wired connections

    Hey thanks! By the way, I've always noticed sometimes the connection "hang," even on my iPad. I learned by renewing the DHCP Lease (on both MacBook and iPad) it kicks it back into gear. It takes a few minutes and a reload... but works perfect. I noticed you mention something in another post about DHCP.

    Switching to DHCP as per your suggestion solved my problem, thank you! I was very frustrated prior to reading your post

    well, my wifi had been rolling along doing pretty well, still on 10.7.4, and so I decided it was time to put some security back on my network, so I changed the security from none to wap2 personal as recommended, and my wifi still worked - for about 24 hours!  Now I am back to wifi drops periodically, and especially when coming out of sleep.  Sometimes, clicking on the wifi icon wil "wake up" my wifi, but other times there is no network selected, and after the wifi searches and finds my network, then I have to choose it.  When I do this, sometimes it connects, and sometimes it does not.  Sometimes the bars in the wifi icon are greyed out and the wifi doesn't work, sometimes the bars are black and the wifi doesn't work.  I have not been able to establish a pettern here - my wifi or lack of wifi seems totally random.  I am back to an ethernet cable to get reliable internet connection. 

     

    I have been from Leopard to Lion - now I think I need a Grizzly Bear.

    This sounds like you have some interference around your computer or WiFi router.   How close are your neighbors?   Are you in a multi-unit dwelling, or otherwise have neighbors next door?   I have one of the Video Sender/Receiver pairs that X10.com sells for letting you wireless send a TV signal to another device.  I had to stop using it because it just killed my Wireless network on 2.4ghz.  There are perhaps many different types of devices like this that are on 2.4ghz.   Does your wireless have a 5ghz band?  If it does, you might try that.  If you have a friend who has a 5GHz router, see if you can get them to bring it to your place to try 5ghz and see if that works when you are having problems with 2.4ghz.
