2 Lion Problems: Waking from Sleep Doesn't Go to Wifi Network; & Can No Longer Finger Swipe in Firefox to Move Backward/Forward

+1 same issue..

Not even using Time Machine and never have so doubt it's related..

Brand new Macbook Air with Lion pre-install.. close lid.. open lid.. doesn't connect to wifi..

Easy to reproduce every time.

Should be an easy fix for Apple..

I shut off time-machine in prefs and it hasn't happened since. Wifi connects readily.

It seems like since I upgraded my Macbook Pro to Lion OS I keep losing my wifi connection and have to re-connect to my router each time I boot up the machine and even during normal inernet browsing. It's very frustrating! I thought the problem was with my router but I changed the router and keep having the same problem. I switched from Windows to Mac because everyone told me Mac OS "is a lot more stable".

Apple- live up to the reputation...fit it!

I bought a Mac book Pro core i5 a week ago with Snow leopard installed

I'm new user of Mac (PC user).

My first steps with a Mac were really amazing.

I've updated to Lion Yesterday.

Now I have some wifi problems!

Before yesterday, I could connect anywhere in my house.

Since i've installed Lion, it is really difficult to find my personal network within the house!!!

I've since the same phenomenon with my iphone 4, with the last updates, and when I find it, I must write my WPA key again and again!

I'll hope they'll find a solution to solve this problem.

Otherwise, what should I do to get back to snow Leopard!

I also have another problem, after the computer sleeping I can not use the touchpad to stop sleeping

I have to press the power button!

No such a fing when using Snow Leopard!

I notice so many people are having wifi issues and it seems to be related to Lion OS. I too have to find my network first, then click the wifi icon next to my network in order to connect. Initially I had to re-enter the WEP key even though I had saved the network.

As for the "wake-up" problem, I usually tap the space bar and that works just fine. I've never had to use the power switch it wake it up form standby or sleep mode.

Good luck fabienc and please let me know if you find a solution.

Sadly I am having the same wifi issue on my MacBook Air after upgrading to Lion. Has nothing to do with time machine in my case. I'm seriously considering downgrading to the previous OS. Has anyone tried this?

Same here except I'm a new Mac Pro. Every day in the morning or when I get home from work, I wake up my MP, fire up Safari and I get the the no Internet connection message. I then select ' Network Diagnostics" and it makes me pick my wireless connection and then it works. I have not just prevented my MP from going to sleep. And this was never the case until Lion. Not a huge deal but this is very un Apple like.

I just spoke with Apple support. They recommended moving from WEP to WPA to fix the issue of losing Wifi after waking from sleep after Lion upgrade. They claim WEP is not supported by Apple (News to me). I did what they said and still have the issue. They are in complete denial that there is a problem. Everyone must start calling in to support so they recognize (or admit) Lion has an issue. Scott

Hmmm....

Switch from WEP to WPA? So apple is no longer supporting simply even having legacy devices exist on the same wifi network, uhm ***?

And of course, that doesn't help me, since I don't bother with either, but instead use MAC address filtering to allow and deny access to my network.

Here is what the documentation says...

WPA2 Personal (AES) is currently the strongest form of security offered by Wi-Fi products, and is recommended for all uses. When enabling WPA2, be sure to select a strong password, one that cannot be guessed by third parties.

If you have older Wi-Fi devices on your network that don't support WPA2 Personal (AES), a good second choice is WPA/WPA2 Mode (often referred to as WPA Mixed Mode). This mode will allow newer devices to use the stronger WPA2 AES encryption, while still allowing older devices to connect with older WPA TKIP-level encryption. If your Wi-Fi router doesn't support WPA/WPA2 Mode, WPA Personal (TKIP) mode is the next best choice.

Note that the use of WEP is not recommended for compatibility, reliability, performance, and security reasons; WEP is insecure and functionally obsolete. However, if you must support legacy WEP devices and you have a newer (802.11n) Wi-Fi router, you may be able to select the WEP Transitional Security Network (WEP TSN) security mode. This mode will allow legacy WEP clients to join your network with WEP encryption while allowing newer devices to use more modern and secure encryption modes, such as WPA TKIP or WPA2 AES. If WEP TSN mode is not supported, then WEP128 with Shared Authentication should be used (with a single WEP key in key index 1). For compatibility reasons, WEP128 networks should use 13-character ASCII passwords.

For reference, "None" or unsecured mode, provides no authentication or encryption. If you use this security mode, anyone will be able to join your Wi-Fi network, use your Internet connection, or access any shared resource on your network. In addition, anyone will be able to read any traffic you send over the network. For these reasons, this security mode is not recommended.

Note: Due to serious security weaknesses, the WEP and WPA TKIP encryption methods are deprecated and strongly discouraged. These modes should be used only if it is necessary to support legacy Wi-Fi devices that don't support WPA2 AES and cannot be upgraded to support WPA2 AES. Devices using these deprecated encryption methods will not be able to take full advantage of 802.11n performance and other features. Due to these issues the Wi-Fi Alliance has directed the Wi-Fi industry to phase out WEP and WPA TKIP.

Awesome. The 10.7.1 update didn't fix it.

same issue here...

to be more specific, after lion upgrade, on waking from sleep wi-fi turns on ok but doesn't automatically reconnect to my preferred network (fritzbox 7390). what i noticed is that it takes a few seconds for the SSID to show up in the wi-fi list (causing the preferred network to be unavailable when the system checks for it - once it does show up, selecting it from the list allows me to connect as usual).

the 10.7.1 update didn't fix this issue for me. i also tried deleting keychain items related to the wi-fi network as suggested in other threads and this didn't work either.

what did work is deleting the wi-fi service from the network system pref pane and then add it again.

My MacBook Air 13" has been perfect—until now.

I made the mistake of upgrading to Lion as soon as it was released. Now I have the same problems. I get up in the morning and even though the lid's closed, the fan is going full blast. The Time Machine icon shows it was backed up while the lid was closed. I also have to restart to connect to my network.

I know Apple will fix this eventually, but I've learned my lesson: NEVER upgrade to a new system right away. From now on, I'll wait at least 6 months. I don't like being a beta tester. That's why I stopped using Windows—and why I'd never go back.

Adding my name to the list of people experiencing the wi-fi issues. I'm also using a Time Machine with Airport Extreme (already on WPA2) and the update to 10.7.1 didn't resolve the issue for me. I have only noticed the issue when bringing my machine back from sleep (but not all of the time). When I go in to Network Preferences to turn wi-fi off it really really lags and takes like 2 minutes to turn Wi-Fi off (get the rainbow pinwheel). Then once I turn wi-fi back on it connects to my preferred network immediately. Never had any issues under Snow Leopard only since updating to Lion.
