Wifi Connection Timeout - Macbook Pro?? Help!

Hello, I figured out what was my problem in connecting to a brand-new Sitecom X3 N300 modem/router. I have a macbookpro and I realized that in the airport configuration it says, among other things:

Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165

I connected the modem/router to my MBP with a LAN cable so I had access to its specs and configurations and I found that the setting "Channel" was "autoscan (recommended)". Apparently, this "autoscan" told the router to fix its broadcast on the Channel 13, which is not in the list above of supported channels. So I forced the router to broadcast into one of the channels of the list and now it works perfectly. Probably, by trying on and on to connect it works as well because the "autoscan" changes from 13 to some other channel. In any case, it is better to check.

Revede, I was having a connection problem with my macbook pro. The issue was AVAST free antivirus, this program has a website shield that for some reason locks all of the websites except for some of them. Try disabling this feature of this program, or uninstalling it.

Hope this helps

This absolutely worked for me. We'll see if the problem returns, however. If it does, I'll just hop on my iPad and change the router channel again. Much easier than factory reseting my router every time, which was my previous solution to this problem. Thanks so much, Max!!

Ugh... spoke too soon. Apparently, my MacBook Air will decide it doesn't like what ever channel my router is set to and will drop the connection. This happened yesterday and so I changed the channel and found my MBA would connect again. Then, just a few hours later, it decided it didn't like the new channel. So today I had to go through and try each channel that my router had available (only 1-11) until I found one that the MBA liked. This is not a good thing. I really hope Apple gets this sorted with an update soon. I really don't have time to take my laptop in. I've had some serious bad luck over the years with Apple and their customer service...

Forgot to mention under Router settings:

Channels - I tried 1, 6 and 11 as suggested on various forums. None of the channels made a difference. I think I left it on 6 though. I also did the handy wireless scan to see which channels my neighbors were using, just in case. Channel 6 seemed good to me.

With my Mac Book Pro (2.4 GHz/ core i7) running OS X 10.7.5 (newly updated 3 days ago) I just experienced something very similar. System and wifi connections have been working perfectly … and then, this morning, the Mac Book gets the wifi timeout error. Three other devices are perfectly connected to the wifi, and a wifi router restart doesn't help. I CAN connect with the Mac Book via blootooth on the iPhone.

Not wishing to through out all the wifi settings (different servers I frequently use), I was reluctant to trash network preferences. So here is what worked for me: I simply removed the wifi router from my collection of "known networks" and loaded it again and reentered the password. Then .. bingo … it's in place again.

A simple remedy that might work for many of you experiencing the same timeout error.

cheers

I don't think this will solve the OP's problem but I thought I'd mention it just in case. I was thinking about how some folks mentioned turning off bluetooth solved their problem. This won't work for me as I use Bluetooth for a lot of things. Secondly, I had made no recent changes regarding how I ise Bluetooth devices. So what other changes had I made? i recently bought a USB 3.0 hub that I placed directly behind my MacBook Air. So, I simply dropped the hub behind my desk, rather than leaving it on the same surface as my MBA, and voila--suddenly the MBA could connect to my wifi again. Apparently, the hub (a cheap Dynex I got from BB on sale for $20) kicks off enough radiation to interfere with the MBA's wifi. Anyway, I hope this helps someone!

Guys I think I SOLVED this. Personally me it helped when i disconnected my external HDD from my MacBook Pro. I have connected to my home wifi. When i connect HDD to mac again - wifi keeps connect but network doesn't work - strange, but worked for me 🙂

Good grief, thanks for posting!

I was having the same problem with my iMac and was ready to blame Yosemite, my router/modem, even Chromecast, anything. strange that only my Mac was affected, all other devices connected fine. Tried nearly everything on the net, read you post about the hub, moved my cheap USB3 hub back and bam! All systems are go!

Thanks!

The problem is a known to Apple. I had the same problem with a new MacBook. The helpline sent me a link to some instructions - from BT - on how to distinctly label the two SSID hub frequencies (2.4GHz and 5GHz). The Macbook was unable to tell which was which. This resolved the problem for me.

Mine was doing the same thing a couple of weeks ago. I finally figured it out it was wanting me to install an update. It's running and connecting, for now. My Macbook pro is 10.6.8. I'm sure i'ts a matter of time before it wont be able to run again due to outdated system. Turn on your airport and try to update it by going to your Apple icon (top left) click on "check for updates". It wont have any problem checking for those, you'll see. LOL. Hopefully it's as simple as that, and good luck, honey

Unbelivable, it seems like you never read what liskabee wrot!!!👿

Happened to me and I tried all of the above but the only thing that worked for me was to disconnect my wifi for 60 seconds, restart and everything began working perfectly again.

Hope this helps.

simply renew DHCP and you'll be able to connect to wifi

i tried various fixes but this worked for me.

wifi>open network preferences>advanced>TCP/IP>renew DHCP lease

Hey guys,

Changing to channel 6 as another poster stated worked well for me.
