MBA connection and restore problems

Right, so basically my MBA seems to drop the connection every 3 minutes or so. Well, not drop it, it remains connected, but it just stops transmitting data. Its really strange. Regardless of if im using mobile BB or if im using the wireless, it just stops transmitting data. Does anyone know what the problem could be? Im fairly sure its not hardware as it does the same if I use mobile BB and its not signal, as my Mobile BB has full signal and my wireless is wireless N.
So I thought it could be hardware, so I tried to restore it OTA, but when I select the restore disk in my imac (From my MBA) the World appears and spins, and then the machine has a kernal panic, so I managed to get hold of an external disk drive, and when i try to do it from there I just get a blue screen for 10 minutes, and then it starts up as normal,
This coupled with the connection problem is really doing my head in. All i want to do is for the bloody thing to stop dropping a connection so I can actually use it!
Anyone got any ideas how to get round my problems without having to send it to apple or buy extra pieces just to restore it?

Elk;
Thanks for the quick response. Here's what I've got;
Belkin 54g Router. Yes, the firmware is current, the other computers I've got connected are two Toshiba Satellites, and my son's MacBook Pro, no problems with any of them. The Toshiba's are running Windows Vista and Windows 7RC1 and the MacBook pro runs OSX 10.4.? No encryption and anywhere else I take the MBA I have the same issues.
History; Originally the MBA ran OSX 10.4 when received, updated to 10.5.6 I believe and that's when the problems began. Currently it has an 80G HD, 2 GB of ram, and 58GB of free space available.
I've tried everything I know, and a few things I've made up (ha) and while I'm the IT guy at work, 98% of my training and experience is Windows based so learning OSX has been fairly easy, with the exception of the wireless issue.
I'm open to about anything to sort out what the problem is, but from what I've read here, there are quite a few people with OSX 10.5 and better having the same issues. I'm simply hoping someone has sorted this out.
Thanks in advance for any words of wisdom.

That is a baseband error. Has your phone ever been illegitimately unlocked? If so, that problem happens. If you haven't jailbroken/unlocked, visit your local Genius Bar.

Broadband connection and speed problems

Hi,
On Wednesday morning my broadband connection went down and could not reconnect from 600am til 700pm. It did manage to get a connection to stay up at around 900pm, but since then the connection has dropped about four times a day.
I have checked my equipment, wiring etc, connected directly to the test socket, using a new ADSL microfilter etc etc. I have also checked for known problems in my area and have done some quiet call tests(17070).
There are apparently no problems in my area, but a couple of the quiet call tests were crackly.
Since last night (Friday) at around 900pm the connection has managed to stay up but my connection speeds, both up and down are much much lower than they used to be.
Since Wednesday night I have performed some BT speedtests.
D/L Profile for my line is - 17.64 Mbps, but actual speed currently varies between around 8 and 11 Mbps.
U/L Profile for my line is - 0.83 Mbps, but speed currenty varies between 0.01 and 0.3 Mbps.
Before Wednesday, my download speeds were typically 16-17Mbps and upload speeds were typically 0.8Mbps.
With very little variation.
I have included some stats from my BT HH3...
Wednesday nights ADSL Line status, after I managed to get a connection to stay up. below;

One thing that stands out is the Noise Margin of 4.9dB and now 3.2dB. I gather that these values are on the low side. Is 3.2dB acceptable?
I assume my line attenuation values are low as I live very close to my local exchange. I assume that these values are good.
There are some CRC HEC and Error Seconds values. I must admit that I dont fully understand these but I assume these are not good.
One other thing worth mentioning is that the phone cable to my property comes along my front wall over from a neighbouring property. Whilst checking this cable this morning in the daylight, I have noticed that someone, most probably my neighbour, has pulled the cable way from its fixing on the wall in order to put a fence post up on the wall.
The fence post has been there for a few months, with no apparent affect ro my phone and broadband, but I'm concerned that this could have damaged the cable, splitting the shielding or breaking a wire in the cable, or perhaps loosened the connectors to the juntion box it is connected to on the neighbours wall.
Could damage to the cable be the cause of my connection and speed problems?
Also, is it possible that my BTHH3 is faulty?
Any advice would be very welcome.
Thanks

A little more information.
I have noticed that on a number of occasions when making or receiving voice calls, the broadband connection completely drops. It doesnt happen on all calls, and doesnt seem to happen when just going 'offhook' and listening to a dialling tone.
There is a definite crackle and hiss on most of the voice calls. But only seems to be audible on the home phone.
After a little browsing, I came upon a logging program "Routerstatshub". When I leave this running it logs changes to ADSL stats.
Looking at the logs, I've noticed that when making voice calls, the upstream noise margin always seems to drop considerably, sometimes down to 0dB.
On some calls, both upstream and downstream noise margin drop to 0dB and the broadband connection drops.
I have also noticed that upstream line attenuation increases from around 5dB to around 28dB every hour or so. This doesnt appear to coincide with the voice calls.
CRC and HEC error increase dramatically at the same time as the noise margin changes. HEC goes up by 10s of thousands.
I'm still directly connected into the mastersocket with a new microfilter and no extension cable.
By the way, my connection speeds went down to an all time low yesterday , 1.7Mbps down.
I have now replaced my DECT phone with a corded phone and will make some more voice calls to see if that makes any difference.
Any ideas about what the problem could be would be greatly appreciated.

Problems of change of apple ID, wifi connection and restore backup

Met the following problems with my iphone after change the apple ID from hotmail account to gmail account and restore backup from i4 to i5.
1. Cannot make any purchase / update as it keeps show the OLD (hotmail) apple ID on the iphone.
2. Incomplete data transferred to i5 from i4. (Empty data of some apps)
3. Unable connect wifi and asks for the password and says unable to join the network even I enter correct password. Curious that wifi works perfectly fine on i4 even other devices (laptop, not Mac).
Why this happen ? Any suggestion or someone can tell how to fix the above problems ?

To change the iCloud ID on your device you have to go to Settings>iCloud, tap Delete Account, then sign back in with the new ID.
If you are changing to a different iCloud account and need to migrate your data to this new account, when you are prompted about what to do with the iCloud data be sure to select Keep On My iPad. Then when you sign into the new account, when prompted choose Merge. This will upload the data to the new account.

IPhone 5 shut down and restore problems

I was using my iPhone 5 and it was at about 6% so I shut it when I went to go plug it in it wouldn't turn on for a while, I tried many different chargers. Then at once it started to turn on the apple sign shows up and it appears to be turning on the goes black and repeat that over and over again. So I looked at different support things and have tried to restore it, I have tired about 13 times now and each time it loads till about 9.0-10.0 Mb then either tells me I've lost connection to Internet access when I know I haven't or else it starts to load the apple sign on my phone then shuts off again. Its hasn't works for about 24 hours now and it has become to the point where I'm very upset with it. If anyone has a solution please your help would be greatly appreciated !

I'm having the same issue with my iPhone5. It just started yesterday afternoon. The "hard reset" as you suggested worked once. However, it shut down again only one hour later. It didn't turn on (even with the hard reset) for three hours when the hard reset worked again. I hooked it up to iTunes and restored my phone and thought that it would fix the issue. But after being on for about two hours, my screen got vertical lines then turned green and shut off again. I haven't been able to turn it back on no matter what I do all night and all day today.
It doesn't matter that the phone is plugged in or have 100% battery power. It just won't turn on again.
I have an appointment at my local Apple Genuis Bar, but I'm not sure what they can do as I'm not sure if this is a software or a hardware issue.

Itunes connection and Passcode problem (Please Help!!)

So, my computer recently was broken beyond repair.. so when I got a new computer and redownloaded itunes i tried to connect my itouch to charge it and i noticed it said "Itunes cannot open ipod in library please imput password on ipod" I never put a password on it... aparently one of my friends did. So I was being a total DA and attempted to guess the password too many times now the ipod's disabled untill i can connect to itunes and itunes wont let me connect untill I get the password, I'm at a total loss please help!

You need to place the iPod in recovery mode and then connect it to your new computer and restore it via iTunes. Note that you will lose all content on the iPod. You can redownload apps at no additional cost provided you are signed into the same iTunes account that originally purchased the apps.

Puzzling connection and power problems

I spent a frustratingly large chunk of the holiday week struggling to interpret and respond to two serious problems with my computer setup and Internet connection on the Sunday after Christmas. See [this thread|http://discussions.apple.com/thread.jspa?messageID=10811325] for background.
After returning the APC UPS to the store, I crossed my fingers, went to a different retailer and bought a [Monster MDP 900|http://www.monstercable.com/productdisplay.asp?pin=5016] basic surge protector (which actually cost more than the APC UPS although this store's discounting is comparable to Best Buy's).
I connected the G5, its display, and the G-drive to it and left everything else connected to the old APC surge protector that I had “borrowed” from another room after the Belkin did its apparent kamikaze deed. (Side note: The back of the Belkin says its "maximum load" is "15A 125VAC 80HZ 1875W." Since my G5's CPU alone can draw up to 450W according to [this article|http://support.apple.com/kb/TA24037], and there was a ton of other stuff connected, I guess I was pushing my luck? Although it did tolerate that load for a little over a year.)
Then, stubborn sort that I am, I reintroduced the old Linksys router. So far, so good. I used both the G5 and my G3 beige for many hours yesterday. No noticeable problems with Internet connection or anything else. And I had even fixed (I think) the G3's glitchy monitor connection when something triggered the memory of stashing a spare adapter that NEC had sent me eons ago. Bliss
This morning, I decided to try to re-establish communication between the G3 and the G5. That didn't go well, and in the process I wound up in the G5's network prefs panel and was aghast to see Ethernet 1 status (with a label noting that its IP address was "self-assigned") switching back and forth between "connected" and not-so-good statuses, including one that said the cable wasn't connected. This appeared to be the same problem I'd battled last Sunday--when the genius in my ISP's phone support, clearly never breaking a brain sweat, dismissed it as a router malfunction. Can't entirely blame him, though, because it did seem to go away when the router was cut out of the loop. (The G3's connection, I should note, did NOT seem to be similarly afflicted today, but I can't compare that aspect with last Sunday's episode, because the G3 wasn't in use then.) That was the day when, some hours later, the surge protector failed, so I assumed the impending failure had caused the router to malfunction, and that the load reduction from taking out the router had kept the surge protector going for a few more hours, though I was not 100% comfortable with that theory.
Back to today. I shut down, connected the cablemodem directly to the G5 instead of the router, reset the modem, powered up. No change, same syndrome.
After some fidding, including copying DNS server addresses from an old configuration that doesn't work any more, I established a new location that lit up, and it's behaved perfectly for the past couple of hours. No more warnings in prefs about a self-assigned IP address (which is a completely different series of numbers now).
So, it seems that the "flickering connection" and the failure of the surge protector several hours later last Sunday (long after the connection seemed to have been stabilized) really were completely unrelated, and that my old router was probably innocent in both cases. (I haven't yet screwed up the courage and energy to try reintegrating the router again.) At most, maybe all the on-offs of the cablemodem and router during my diagnostic session with phone support accelerated the surge protector's breakdown. Right? Am I missing anything here? Any tips, insights or similar experiences anyone can share?

This. Is. Driving. Me. Nuts.
I put my router back online yesterday and ran both the G5 and the G3 beige for many hours with no apparent hiccups or other problems of any kind.
But this morning was another story. I used the G5 for an hour or so, then booted up the beige just to see if everything was still okay. I watched the Network Prefs panel as the beige was starting up. As I feared... the network status started cycling again on the G5. (The beige did connect and loaded a few pages quite snappily.) As in previous episodes, the status was changing every few seconds from "Connected" to "Cable not plugged in" to "Unable to determine status" or "No IP address" or some other error message.
I shut down the G3. The G5's network status changed one last time after the G3 had powered off, then remained steady.
I left it on, went out on some errands, and came back with some new Cat6 cables (Geek Squad brand from Best Buy, too bloody expensive, but it was either that or buy something I didn't really need at Amazon to get free shipping for the cables, and then wait, which I did not care to. I don't like the connectors, I have to say, but that's a side issue. At least I hope it is.)
I shut down, cabled, and went about trying to resuscitate my little LAN. No luck, no matter what I did. All kinds of trial and error not worth detailing IMO, except to say that the G5 seemed convinced that it was disconnected from Ethernet as long as it was plugged into the router (in either of two router ports I tried). I have given up on the router for now, but I still don't really believe it's the culprit.
I think I did try switching the cable to the second Ethernet port on the G5 at one point and it didn't help. I guess that was while I was still trying to make the router work. (My brain is getting fried...) Then I decided maybe that particular cable was bad. But before I decommissioned it, while it was connected directly to the cablemodem, I plugged it into Ethernet 2. And we were alive. I don't think I even had to reset anything.
I surfed for a while and then couldn't stand it any more--I had to shut down, switch it back to Ethernet 1 and see if I got a green. I did, but unlike before, we had the dreaded "self-assigned IP address" and the computer was offline. Oh, that again. I went into Network Diagnostics, which as usual directed me to restart the cablemodem. After that, it connected, but there was one last hiccup where it flashed "No IP address." Then the address changed to a 66 number, and it has been steady since, for at least an hour.
Something else that I haven't mentioned: My TV in the same room has been suffering from intermittent, very brief audio interruptions for quite some time. Two, three months I'd say. Maybe four. Now and then the video freezes, too. But strangely, the TV in the bedroom hardly does this, if at all. I suppose the cable splitter could have a partial or mixed malfunction though. I'm not sure of the relationship in time of those symptoms to my Internet problems, which I now suspect started a while back when my old static-IP configuration unaccountably stopped working and I reverted to the previous one.
Whether or not the TV symptoms are related, I'm really beginning to think this recurrent syndrome has nothing to do with my computers or my router. I think it's time for a house call from the cable company (including, maybe, a new cablemodem). Agree? Other ideas?
Thanks...
Oh, but wait! Just now, I decided to try to log in to my router and see if there were any bad settings left over from that old configuration. I pulled up the cable that was attached to it, thinking I'd plug it into Ethernet 2... and Ethernet 1 went down. Now its network status says "Cable Unplugged" again. WTH?? I don't think the cable even touched anything as I drew it up. Again the router was NOT connected at this time to anything except power.
I hot-swapped the G5's cable back to its Ethernet 2 port, and now it's connected (but had a self-assigned IP again; restarting the cablemodem fixed that).
Maybe it isn't the cable company's problem after all... maybe the G5's Ethernet 1 port is tired and needs to be put out to pasture....
See why I say THIS. IS. DRIVING. ME. NUTS. ??? Help please...
UPDATE: We are live--via my router, connected to Ethernet 2. Starting to look like an intermittently sick port (Ethernet 1), as DaddyP suggested?

TOSHIBA Canvio Connect (EZ) Boot up and Restore Problems

I just recently purchased a TOSHIBA Canvio Connect (EZ) portable hard drive to back up my HP Pavilion. The backup went well. Following the Canvio instructions I created a boot drive on a USB Flash drive. Then I booted up the PC using the Flash drive and pressed the F12 Key as per instructions. I tried several times booting using the drive and pressing F12 but most of the time the computer just comes up normally and twice I got a screen that read UEFI Boot Services with the option to select UBFI IPV4 Net Card or to select UBFI IPV6 Net Card. The screen shown in the instructions said I would have option to select USB to bring Up EZ.

HP Pavilion. ... pressed the F12 Key as per instructions
You are dealing with the computer's BIOS/UEFI now. That has nothing to do with the external drive.
The instructions probably assume a Toshiba computer. You'll need to consult the HP people.
HP Support Forums
Ask them how to set up the UEFI in your machine to boot from a USB flash drive.

Iphone Sim Card problems and updating and restoring problems

I bought a iphone about 1 year ago and about 2 months ago i was not able to see any wifi connections in the area or connect to any even though i was sure that there was a wifi nearby and my fellow coleauges could connect to it with their iphone. I thought that this might have something to do with the "restrictions" so i went to turn the restrictions off but realised that it had a passcode that i had forgotten. I wasnt able to restore it within the iphone so i restored it from my computer. Once i had finished the iphone had a " connect to itunes " on the screen and it said that there was no sim car installed, even though there was. I tried cleaning the sim card and everything else, i tried connecting it to itunes but it just said no sim card installed. Now i cannot use my iphone or cant even activate it. I have also tried to restore it in recovery mode but ended up with the same problem. Please Help.! Thanks

Connectivity and Video Problems

I have a 5G 30GB iPod. I had no connectivity issues until I downloaded iTunes 7. After I downloaded iTunes 7 my iPod would shouw up in windows but not in iTunes. I followed the instructions about 1. plugging in the ipod 2. stop the ipod service 3. start up itunes. My iPod then showed up in iTunes. I tried to install the new apple update software (Version 1.2 I believe) and my iPod disconnected itself and the computer continued to search for the iPod which it had just ejected. I simply plugged in my ipod again and decided to not install the update. It sync'd up just fine updating my podcasts and music. As soon as it was done updating my ipod it seems to autoeject itself once more so I am not able to change any preferences. This was annoying, but didn't bother me too much. Recently I updated to iTunes 7.0.1, and I added a video which my friend had sent me to my iTunes library. I then connected my ipod doing everything that I normally do. iTunes removed all of my videos from my ipod and then updated my music and podcasts. Now I am stuck with no videos on my ipod. I can't change any preferences because my ipod will not remain connected to itunes. Has anyone else had a similar problem, and is there any known fixes?

IOS 7.1.1 update and restoring problem

Hi there,
So this morning I woke up and my iphone 4S came up with the 7.1.1 OS update. I decided to update it so i clicked install. Once i clicked install the verifying update message came up (which was expected) and i thought ill put it on our little black charger usb that plugs into the DVD box. I walked away and came back and I saw the apple logo come up like the phone was turning on. I automatically thought okay its almost done. So i left it for another ten minutes and went back. When i took it off it came up with a message saying i didnt have enough room. I began deleting a couple of photos and apps and clicked install again although i didnt put it on charge. After about ten minutes I looked back and my phone was off so i held the lock button to turn it on. It started with the apple logo coming up like it was starting up but then a charger plug came up pointing towards the Itunes logo above.
It wouldnt let me do anything else. So i plugged in into the computer and a message came up saying something along the lines of "this phone needs to be restored".
clicking okay there was an option saying restore phone. Realising it was the only the I could do I clicked the option with pain (knowing all my photos would most likely be deleted).
A loading bar began saying 45 minutes so i left it for about 30. I then came back and an error came up saying it could not download, network connection lost or something.
Does anyone know whats happened to my phone or know how to at least restore it? Even if you have any input or possiblities of what you think might be the problem please comment!
Also if there is a way to save my photos please tell me
Thanks!

HT201412 Iphone 3gs not turning on and restoring problem 5

Hello, my iPhone crashed it wont turn on. When im connecting it to my itunes, it ask me to restore it. Im restoring it and after while the loading screen turn off and on the i tunes the error comes up.
"The iphone iphone could not be restored. an unknown error occurred (5)"
What should i do to get it working?.
Thank You.

You will have to restore it. It will be restored to the last backup you did when you synced with iTunes, which is why its a good idea to sync frequently.
