Wifi problem and Lion (my solution)

Hi guys
Like so many other people, I've had problems with my wifi network at home after upgrading to Lion.
My mbp could'nt couldn't detect my wifi network (wpa-psk/AES. No SSID broadcast). My solution was to change the broadcasting channel from 13 to 8. Works 100% now.
(I could actually find and connect to my network, but only after connecting to a neighbors insecure access point, (connected to the same router as my AP(router) located in the buildings basement). My wifi would pop up after only a few seconds of being connected to my neighbors AP, and only then)
After having changed the channel, I connect instantly to my own AP every time.

I called into apple care and the rep offered a solution the problem which worked perfectly.
He mentioned that 7.1 would fix the issue for new users going forward.
Steps to Fix
1. Open Network Preferences
2. Click Advanced
3. Remove ALL of the Preferred Networks (should be completely empty when completed)
4. Ensure that Remember Networks is checked
5. Click OK
6. Select your network in the Network Name dropdown menu
7. Ensure that Ask to join networks is checked
8. click Apply
9. Restart your computer
at this point you should be good to go!

On the US keyboard, it's option + 3.
However, when I try to enter that combination in Mail 4.4 or the Safari 5.0.5 browser, it is apparently has some reserved function and opens another window. It does seem to produce the correct character in Firefox 4.01
If possible, I'd suggest changing the WiFi password so that it does not included any 'reserved' keystrokes.

What model of Mac? I have a MBP running 10.7.3 and do not have that issue. From the other couple of posts I've seen about it, it seems to be maybe an issue with some iMacs? Have your tried searching the Lion or iMac forums for similar issues, just to see if anyone has hit on why it is happening?

Strange that your dealer could not help.
When my car was in for its 6 month service in July/August I mentioned this problem to the dealer service dept (Northway Honda, Bundoora, Vic)
The person booking the car in told me an update to the software was needed and that they would do the update.
I don't know if it was free as there was no specific listing of a software update on the invoice - just a lot of item numbers.
All has been well since

I can hear people on call but sometimes they can't hear me, it maybe fine for afew mins but then sound drops again? Anyone have this problem and find a solution? Thanks.

I have an Iphone 4 13.5 GB, iOS 7.1.2. Currently when I make a call or someone calls me, I can hear people on call perfectly but sometimes they can't hear me. It maybe fine for afew mins but then sound drops again? Anyone have this problem and find a solution? Thanks.

I have taken it back to the Apple store genius bar, but they say they don't see anything wrong. Well unless you use it all day and experience the problems when they happen, you wont see anything wrong. But there are lots wrong with it. But this would be the same store as I purchased the phone. And they backed up my old Iphone 4, but were not able to get anything to load back onto my new phone. So, I lost pretty much everything. But over time, some of my contacts have started showing up, although i am still missing over 800 of them.

Just wondered if anyone else is experiencing the following problem and knows a solution. I know a few friends who are also having the issue so its obviously something wrong with IOS7. Basically I have an iphone 4 and upgraded to v7 and most recently v7.

Basically I have an iphone 4 and upgraded to v7 and most recently v7.0.2. When I am on calls the phone started to beep and vibrate and sometimes change the call to speaker. It seems to be that the screen is sometimes active whilst on calls and so my ear is actually pressing the buttons and hitting numbers or changing it to speaker phone. It has also cancelled a call a few times.
This is extremely annoying and makes every call a worry.
Any ideas of how to solve this problem?

My Iphone/ Ipod touch 4th gen WiFi problems and solution

Just wanted to let people know the problems that I had with my 4th gen Ipod touch and Iphone 4 WiFi connections (and my solution).
I was having consistent problems with my WiFi connection at home - my devices were connecting fine to the router and apparently the signal was full strength; however, nothing was working properly (internet, itunes, app store). To be specific the devices would work for 5-10 minutes but then the connection would start to falter. My other wireless devices were working fine (HTC Hero, laptops etc.) - just the ipod and iphone seemed to suffer from this signal problem (although the router was always apparently connected).
Obviously, I read countless forums to try and diagnose the problem. There seemed to be a litany of possible causes and I tried the following to resolve the issue:
- updated router (Netgear WGR614 v6) firmware
- rotated wireless encryption (WEP/WAP/nothing)
- changed router channel
- reset router power
- reset network settings on Apple devices
- changed g and b settings on router
Nothing seemed to work so I began to question the hardware i.e. the router (which I knew was working from my other devices) and the iphone/ipod.
I tested my iphone and ipod on other wireless networks (McDonalds in the UK has free WiFi) and found that, in contrast, they worked fine on other networks. I had read a few posts from people saying that my router was perhaps too old. So as a last resort I bought myself a new router (Netgear WNR2000 v2). I was loathe to do this earlier in case it didn't work, since reasonable spec routers are £50
Anyway it worked ... straight away. I have tested the new connection at home using this SpeedTest app. D/load = 9.01 Mbps, U/load = 0.46 Mbps, Ping 65ms. The router is using the full encryption (WAP2 something ...) and N connection.
As you can probably tell I'm no WiFi expert - I just wanted to post this in case people are having similar issues with older routers. I wasn't able to find any definitive advice and solutions from other users so I though I'd contribute here, which I guess is the first port of call for new Apple users, like me
I bought the new router 10 days ago and have been enjoying my full speed connection ever since - touch wood. Hope this helps.

Sounds like an intermittent contact problem some where eon the logic board. Hard to trace down and fix

My wifi problem -- and solution

I realised this morning that my new iPhone has been using EDGE the whole time. You can easily see across the top if you are connected to wifi (it uses the airport-style signal strength symbol) or EDGE (symbolized by a square icon with an E in it).
I didn't realise that. Ah well... When I looked at our WiFi network and reviewed the details, I saw we weren't connecting at all. I have seen there are a few posts on the apple discussion forums about encryption problems--and we use WEP encryption. So, I told the iphone to forget the network, then reconnected and specified "WEP ascii or hex" instead of "WEP password" for the password.
Now, everything seems to be fine. EDGE is OK for when you're out and about, but at home (or work!) I'd want that wifi actually working.
MacBook Pro Mac OS X (10.4.8) 2 GHz Intel Core Duo

I have an older Airport Extreme base station (g not n?). I have tried setting both a WEP or a WPA/WPA2 Personal password. However, even though all of these password settings work with 2 different MacBook Pros, I cannot connect to my iPhone with any password. The only way I can get wireless on the iPhone is to set the security on the base station to "none" and thus use no password. Thus, my only protection from the outside world is that I have a closed wireless network. I also tried using the WEP HEX/ASCII option on the phone (with a WEP password) but that does not work either. My passwords are just normal passwords with a mix of letters, digits and special characters (e.g. $), currently 13 characters all together. I don't understand what people are talking about when mentioning that passwords must be of a particular length and only have letters and digits and then entering the password starting with an extra $. Using Macs of various types with my Airport Extreme base, I have never done this. Any suggestions? This is important to me since it appears that I have no AT&T reception at my home even though the AT&T coverage tool (which I used before purchasing the iPhone) said I should get moderate coverage.

Is there any way to solve the wifi problem with lion?

Since upgrading to lion my iMac has been having severe problems connecting to my wifi router. As long as it doesn't go to sleep it is fine, but if it does then I have to restart the computer to connect to the router. I know that it is lion as I've got 2 iphones, 2 ipads, and 2 laptops in the house all operating without problems. Please any help would be greatly appreciated. I tried contacting apple and they won't help me unless I pay them, or sign up for apple care. I already paid for the **** computer and the OS why would I pay them to address an issue that is clearly on their end when my computer is still under warranty?

There's a number of things you can do to try to diagnose the problem, and hopefully it doesn't have to do with a hardware problem.
I think the number one reason people are having problems with Lion is because most of the installations are UPGRADES, not CLEAN installs. While it's much less of a hassle for an upgrade rather than a clean install, weird and random problems can arise from an upgrade to an OS.
Another reason is the fact that this is a dot zero release, meaning it's version 10.7.0, meaning there are bugs that have not been fixed yet.
So the first thing you can do is to repair permissions in Disk Utility and restart your Mac. I don't think that will exactly fix the problem, but it's a step.
When it's restarted, wait a few minutes and put it to sleep and wake it up and report back.

Beware the Security Update - How I fixed my WIFI problem and a question

First of all I have read the "Latest Update from 21 January is A Disaster" thread and I basically agree with Andrew is Stuck so please don't feel the need repeat any of the stuff about it is not a bug in the update etc etc and I should have a Super Duper clone to hand etc etc . I have read that stuff. You are probably right but they should write on the Security Update info panel - "Be Careful this could really ruin your day".
I am ****** off and stressed out and I need to rant and I am not looking for that kind of lecture - even if it is partially or wholly true. I need to feel positive by warning people the way I wish I had been warned!
NB I am near the end of a professional dance tour as Musical Director running music on Logic on my MBP and it has been working fantastic - not a single glitch in 6 weeks. I would never upgrade my OS or Logic in the middle of job like this BUT Security Updates have always seem like something you should install because they will protect the Mac or protect against any new viruses etc. I have never had a problem with them before. (THAT ATTITUDE WILL NOW CHANGE!!!)
This update has caused a lot of people a lot of problems (check out this forum) and it has caused me more real world problems than anything I have downloaded and installed from anywhere in the last 3 years. Thus it has nothing to do with Security!!! HOw any people does a Security Uodate have to goose before it becomes an unsatisfactory Security Update?
This security update suddenly stopped my WIFI working and put me in a real hole.
(I am sure you don't care but I have a meeting tomorrow morning that I needed to do 3 hours of prep for including looking at VIDEO online. And the Security Update has just put paid to that. )
After 3 hours I have just got WIfi back- here's how:
I repaired permissions twice with Disk Utility - no joy. I found I could get online when I booted in Safe Mode (and I could get online with my Iphone on the same WIFi setup) so I knew it was not the router - though I did switch the router on and off a few times,
When I initially ran Repair permissions there was loads of things needing repair. I ran it again and 2 remained:
usr/share/derby it keeps trying to repair
and one of the package contents of the ARDAgent.app (System>Library>CoreServices>RemoteManagement>ARDAgent.app>Contents>MacOS>ARDAg ent) had a warning attached that it in the Disk Utility Repair Permissions report that it had been modified.
So I restored ARDAgent.app from a Time Machine Back up and replaced the offending file when in Safe Mode (Restart with Shift held down). - using Ctrl Click to open the ARDAgent.app package contents.
This seemed to sort it all out for me.
I guess people need to look in their Disk Utility Repair Permissions reports and see if any esoteric system files have been goosed by the update and see if they can get them back - although if you don't know what you are doing this could make things worse......
Anyway I DO have questions:
If this hadn't of worked:
1) Would reinstalling Snow Leopard from disks have upset my preferences, installs of Logic and Audio drivers and 3rd party application installs and the rest?
- the main stressor when this happens is not trying to lose the whole day.
2) Is there a way of just restoring the System from a Time Machine Backup or a SuperDuper clone or do you have to restore the whole state of the entire Hard Drive?
Best
Tommy Banana
PS I feel better now. Thanks for listening.

The fact that you saw no glitches while running Logic before applying the update means almost nothing because that uses only a small subset of system resources. Far more significant is that Safe Mode restored some missing functionality: because it disables non-essential items like user fonts, third party drivers, & so on, it points to problems in those areas.
Equally significant, the fact that there are relatively few reports of post-update problems among the several million Snow Leopard users points away from the update itself as the cause of your problems.
Separate & apart from that, it so happens that I'm a sound engineer/system designer/board operator with nearly 40 years of professional touring experience. FWIW, I never have & never will update the software of any system I must rely on professionally (whether it is running on a Mac, a PC, or dedicated hardware) unless & until I can thoroughly test it first and I have a trustworthy backup/recursion strategy to fall back on in case of problems.
I strongly suggest you learn from your unpleasant experience & do the same. I have had far fewer problems with Macs than with PC's, but nothing is 100% reliable to begin with. Changing the OS software part way through the tour is just asking for trouble, no matter how reliable that has been in the past. Even if the budget allows for nothing better than a stack of burned CD's & a couple of consumer grade CD players, no professional tour can afford to be without some fallback strategy in place. That should be self-evident & require no warning from Apple or anybody else.

Iphone 4 (White MC604FB) Update iOs 6.0 - Wifi Problem and iphone bug when trying to unlock on call receive. Is this a known bug ?

Dear Members (and Apple Team)
I have two iphones 4 and two bugs on the white one

2/ Is the second gen (White MC604FB)
I both uptdated the into Update iOs 6.0 -
Bug 1 : With the white iPhone 4 i have a real Wifi Problem, as close as 5 to 7 meters from any WiFi spot, i lose the signal, where my "black" iphone at the same time and same distance shows full signal (and tested with safari.... works).
Bug 2 : Once the white iphone is in "stand by" when trying to unlock on incoming call, the touch screen works and receive the touch information, but it bugs on trying to unlock to receive the call. (very very anoying :o) have to call back almost every time.
Are those already known bugs ? Is there a fix ?

I solved the problem. Had nothing to do with Mac or iphoto. Problem must be my the internet connection to my provider.
Upload at my office worked without any problem. One problem solved, now i am aware with a lot of discussions with my providers helpdesk ;-)
