Roaming on S4???

I had a standard basic Razr, and had full 4g coverage at work (near mexico boarder in San Diego).
Now with my S4 I have at best 3g, and as of this morning its constantly roaming to Mexico instead of connecting to VZW here. Whats going on? This is supposed to be a more advanced phone, so why can't I connect to 4g in the same place I could 2 months ago with an older phone??

I to would like to have this feature as I live and travel near the canadian border and there are three locations near where I live and when I'm in those areas I will get a text message from someone saying "Welcome to Canada! Roaming data may be billed at 2.05 MB per your plan. Turn off data or use Wifi to avoid charges". This while I'm still in the US. I naturally turn off data but voice roaming is still active and if I get or make a call in those areas, Roaming charges are incurred.
It would be nice to be able to turn off voice roaming without having to go into AIRPLANE MODE.
Maybe a someone from a Verizion Customer Support will answer the question of how do we turn off voice roaming of the Samsung Galaxy S4 without having to turn on Air Plane Mode?? Turning off Voice Roaming is available on the Sprint GS4 and more than likely the ATT and T Mobile versions.
Thanks

Huge ntuser.dat.LOG1 since upgrade to Windows 8.1 prohibits roaming of user profile

Hello,
a few days ago my PC (part of our domain) first started to have problems with my user profile. Our domain uses roaming profiles with a size limit of 30MB. My user.dat has a size of 12.5MB. Up to now this did not cause any problems (and does not cause any for
most users of our domain having a user.dat of similar size). However, after upgrading to Windows 8.1 I repeadly have problems with my profile exceeding its maximum size. After checking my profile, I found a ntuser.dat.LOG1 with 12,5MB in size and a ntuser.dat.LOG2
of 2MB. As far as I know these files are used to store temporary transactions for the user.dat. But why are they this large? Together they almost completely fill the profile. As an interesting side node the last modification of ntuser.dat.LOG1 dates back more
then seven days.
What is further puzzling me: ntuser.dat.LOG1 and ntuser.dat.LOG2 are not synchronized with the roaming profile on the server. At least they are not on the server. However there used to be much smaller versions of these files which could have been transfered
before the profile size exceeded its limit. Since these file seem not to be part of the roaming part of the profile, they should not count for the roaming profile size. However, they definitely do. Neglecting the registry files the largest file in my profile
is less than 500kb and there are very few files of this size. I checked locally as well as on our server.
Deleting the local profile and starting fresh using the roaming profile from our server does work for a day or two but then I run into the same problem. Especially, loosing all local profile data is inconvenient. I could start a new with a completely new
profile, but I am not convinced that it is a profile issue. In our organisation my computer is one of the first to move to Windows 8.1. Since my profile worked without problems for years now, I am worried that I ran into a Windows 8.1 issue. As users normally
start to complain about a roaming profile not synchronizing only after their local copy broke, I'd like to make sure that this is a isolated issue.
Anyone else experiencing similar issues? Any hint on how to solve the problem?
Regards,
Oliver

No, I did not find a solution. However, we moved away from roaming profiles and rely on folder redirection only. That works for us. Since we can redirect the most important folders there is no more need for roaming profiles (at least in our case).

Why does 8X always switch to "Roaming service"?

Hello, I've had my HTC 8X for about a month now, since it came out, and I've noticed something kind of strange. For some reason, under the Cellular menu in the settings, it sometimes says my active network is "Roaming service" instead of Verizon Wireless. It happens pretty often, completely randomly. When I'm it's connected to the Roaming service, my data speeds seem to be slower, and I can't receive picture messages. Nothing else seems to be affected though. I can still send/receive calls and texts, and I still have access to a 3G data network. But why doesn't it stay on Verizon? It wouldn't really bother me much, but when I'm connected to Verizon it seems to be much faster.
I know it's not my coverage, because I haven't had this problem on my previous HTC Trophy, and when I'm connected to Verizon, I have more bars than on Roaming service. Also, I don't live in an LTE covered area, so when on Verizon and Roaming, I'm always on 3G.
And if I'm correct, Verizon and Sprint have a roaming agreement, so when I'm roaming, it's free and on Sprint's network.... just want to make sure I'm not being charged for this at all...
So anyways, how can I fix this? I'd prefer to not have to do a factory reset.... Thanks for any replies!

Hello cody503,
Thank you for sharing your wireless question with the community. We understand how important it is to have consistent and reliable wireless service! After all, that’s why you chose us as your wireless provider! I would like the opportunity to clarify this for you! As we all know, Verizon Wireless have the largest coverage in the country but there are some areas that our customers roam off another carrier at. When roaming, you may see the verbiage that you spoke of in your post. Since your Verizon Wireless phone is designed to pick up our network over others, you will experience a HUGE difference in network performance. I would like to confirm that the area that you were in is indeed an extended area. May I ask what city, state, and zip code were you in when you got the “roaming service” notice? Can I assume that you device doesn’t have any liquid or physical damage? Once you provide me with this information then I can check the area and get back to you. I’m looking forward to your next reply.
Thank you…

Entro em Roam e meu iPhone perde sinal da operadora

Pessoal,
Preciso de ajuda.
Tenho um iPhone 4 com o sistema operacional IOS 5.0.1 desbloqueado para a operadora OI. Toda a vez que viajo e entro em outro estado o iPhone perde o sinal da operadora e não retoma. Ja tentei de tudo (reset; reinstalação; etc..). Quando retorno ao meu estado ele volta a funcionar..
Alguem já passou por isso e pode me ajudar?
Obrigado amigos.
Marcelo

Você já verificou as configurações de roaming?
Se elas estiverem normal, o problema pode ser com sua operadora.

How to set up roaming profile on Macs using AD like in windows

I can bind the workstations to the domain fine.. But can someone direct me to instructions of how to set up the roaming profiles ?
What steps do I need on the server ? This is what I've done so far.
I already have OU's for the departments and the users have a shared folder inside their department folder.... \\server\shared_folder\user
I have done the usual things with AD as far as the profile settings on the windows server.
Am currently running Mac OS 10.5 and above
My windows AD runs on windows server 2008
All my windows workstation are able to use roaming profile without a problem.
So far i have tried the so many avenues including..
Make sure the Mac systems are joined to the domain controller and an ADS user can log on successfully. Use "Directory Utility" under "Utilities" menu to join the system to the domain.
Backup all the contents from /Users to the storage or somewhere locally.
Configure automount - Go to "Utilities" -> "Directory Utility" - Select the domain and click "Show advanced options" - Click "Mounts" tab and add automount as mentioned below. Remote NFS URL: nfs://server_name/share_name/path/to/profile/directory Mount location: /Users Additional mount parameters: -P,-T Apply the settings and this will mount the remote shared folder or we can name it as Roaming Profile Space - under /Users directory
Enable roaming profile - Go to "Utilities" -> "Directory Utility" - Select the domain and click "Show advanced options" - Click "Services" -> Select "Active Directory" and click "Show advanced option" - Click "User experience" tab and select the option "Create mobile account at login".
Reboot the system and log in as any ADS user. The Roaming shared folder will be mounted and the user profile will be created on the shared folder
Can anyone kindly assist me

Global data charges with data roaming OFF

I have an issue with both my iPhone 4 and 4S getting incoming global data "leakage" I will call it.
Both are running iOS 6.1.3, which is the latest software update. Both phones are used fairly regulary along the San Diego border with Mexico, and often times on the Mexican side within 2-3 miles of the border. My phones are always set as follows: "Cellular Data -> On" Roaming = "Voice Roaming -> On" and "Data Roaming -> Off" with the iPhone 4S also having "International CDMA -> On"
However, both phones consistently receive incoming global data hits in very minor amounts (0.1 KB to 5.5. KB) when they are in an area where the signal is switching between my USA carrier (Verizon) and the Mexican cellphone towers. I know this because almost every time it happens it is when we are crossing the border or close to the border where the towers are competing for the signal to my phones. In one case I watched as my iPhone 4 switched from Verizon 3G to Extended network and shortly thereafter I received a push notification (message) from my WhatsApp application. The next day it showed the hit on my daily usage as a 6.9 KB hit even though data roaming was set to OFF.
Please don't respond to tell me that the solution is to switch Cellular Data -> Off when I am near the border. I already know this will solve the problem, but the issue is that we want to use the full functionality of our phones in this area as our employment and our residence is right along the border and we don't want to have to suspend data completely every single time we cross the border, which is nearly every day.
The data hits have thus far been in the range of less than 500 KB per month total (almost no impact at $5 per MB) so my concern is not so much with the minimal expenses incurred, it is more the principal of the issue and the problem.
I want to know if there are other users experiencing the same issue so I can have some more evidence to get Verizon to push Apple for a fix. Apple iPhones have consistently had "Data/WiFi/Roaming" issues on its phones since 2008 (or more as far as I can tell) and I believe this is a related issue that has never fully been fixed.
Thanks in advance for your replies of similar situations, regardless of what country this happened in.

Thanks for clarifying. I do hope you had a wonderful trip! You mentioned you were turning the cellular data on occasionally to use a little data. When your data is turned on, even for just a few minutes, your phone sees that connection as a window to look through your applications for any notifications that you've missed and download email and other messages, occasionally resulting in a significant amount of data usage. What were the countries that you visited? When you log in to view your statement on http://bit.ly/xB4iTc, does it show you had a $25 Global Data or $29.99 Global Value plan for any part of your trip?
Thank you

Caller id not working in roaming

HI,
on my iPhone 5 caller id is not working while I am abroad, in roaming.
I am quite supprised with this problem, because all other mobile phones beside iP do this normally.
So far I know this is not isolated case with my iP5, but all iP users I know have this same issue..
can anybody help me resolve this issue.
Thanks,
best regards,
Branko

After erratic behavior of UC520 I decided to reinstall from scratch, configuring again by hand with CCA, not restoring any configuration, and now everything is working well. I think I did a mess with the configuratión using CCA and CLI. Sorry, my mistake.
So for Caller-id the default configuration works well, nothing additional to do.
Paolo, thanks for the help.

Question regarding roaming and data usage

I am currently out of my main country of service, and as such I have a question regarding roaming and data usage.
I am told that the airplane mode is sufficient from keeping the phone off from roaming, but does this apply to any background data usage for applications and such?
If the phone is in airplane mode, are all use of the phone including wifi and application use through the wifi outside of all extra charges from roaming?

Ann154 wrote:
If you are getting charged to use the wifi, then it is possible. Otherwise no
Just to elaborate here, Ann154 is referring to access charges for wifi, which is nothing to do with Verizon, so if you are using it in a plane, hotel, an internet cafe etc that charges for Wifi rather than being free . Verizon does not charge you (or indeed know about!) wifi usage, or any other usage that is not on their cellular network (such as using a foreign SIM for example in global phones) So these charges, if any, will not show up on the verizon bill app. Having it in airplane mode prevents all cellular data traffic so you should be fine

Tablet 2 won't upload roaming profile

Tablet 2, Windows 8 Pro (factory installed), AD domain member, user account with roaming profile.
The OS will download my roaming profile when I log in, but refuses to upload it back to the server when I log off. I've installed Windows 8 (Enterprise) from scratch on two other computers (a Dell laptop and a Lenovo W500 laptop), and on those machines, the roaming profile works correctly. Has anybody else seen this behavior?

AT&T blames iPhone 3G for roaming data charges in excess

This is Outrageous. AT&T Called me Sept. 19 to advise my iPhone service would be cancelled. They are trying to collect $10,000 because the 3G was ROAMING Data in the background ONE day in Frankfurt Germany, 480MB they say.
After 4 HOURS in the phone today (landline) with mutliple customer service agents, a family ready to go on Prozac because of the anxiety caused by this issue, and much heartburn on myself, I am without service and with a Billing Problem that AT&T does not want to take responsibility for.
I swear to GOD, I did not use such amount of Braodband and I certainly can not afford to pay such large sum just because AT&T says so; fine print or not, this is plain burglary!
AT&T customer services blames the iPhone 3G as a device which constantly "in the Background retrieves data from the network", in other words, the data and broadband was not a direct request of me, the consumer, and therefore not a practical application or service rendered, if in fact the 3G pulled such large amount of data as AT&T claims it did.
If someone have had this problem, of hidden, surprise, OUTRAGEOUS charges, and know a way to resolve, please advise. The AT&T customer service people on the telephone have no authority to investigate and clarify. They cannot offer proof of what are 480MB consisting of, and simply demmand immediate payment if marginally reducing the amount on the spot.
What an intimidating group of people at AT&T. I really hope someone in AT&T would look at these cases and realize how illogical and senseless it is to follow this inpersonal, irrational, unethical billing practice.
I hope somebody in AT&T, or in the legal world, can help me out of this!

I complained to the FCC . AT&T Customer Service Reps, after many calls totalling more than 9 hours now, can not break down the nature or the services rendered in the $20/Mb 500+MB they are charging me in excess of $10,000 Dlls. The phone was in my pocket. I used it to check e-mail from my children (no attachments, just text) figuring it'd be cheaper than $2.80 telephone roaming charges, right? AT&T does blame the device for TX/RX of data without user intervention.
"Form 2000B at fcc.gov: To the FCC: AT&T is charging me for 500MB of broadband use in Germany and Netherlands that I DID NOT USE. They argue theri 3G iPhone works in the background without user intervention.
After almost six hour on the telephone in 8 different calls with AT&T Wireless Customer Service, they insist on charging me $10,000 Dollars.
This has caused a terrible amount of distress on me and my wife. I need help to stopthis fraudulent charge of $20/MB at 500MB of data I DID NOT REQUEST to transmitt or Receive. PLEASE HELP ME. I AM DESPERATE AND CAN NOT GET AT&T to accept the fraudulent nature of their claim. "

Windows Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

I have racked my brain and done everything that I know to do for about two weeks now. I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
profiles. It keeps telling me that the roaming profile could not be loaded because of a slow connection. These are workstations that are connected directly to the switch that the DC is connected to. I have tried multiple connections regarding
the layout (DC into the router, router into the switch). The router is a Cisco RV220W. I have two VLANS, one for public and one for private domain. The Private VLAN has DHCP turned off since I am providing it through the DC. I currently
have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port). I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller. The DC can see
the internet fine and the workstations can connect to the shared folders on the server. I can retrieve files by just using the computer name or FQDN. The DC is also running DNS and DHCP. The DNS has the _msdcs setup from when I installed
the active directory role. I have attempted to assign static IP addresses to the workstations:
IP:                     10.0.0.80
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:        10.0.0.12
I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
The server is assigned:
IP:                     10.0.0.12
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:         10.0.0.12
The DNS entries have forwarders that forward to my ISP DNS servers for lookup
I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
I've lost my patience with this project and am sinking fast. Can someone please offer some advice as to what I've done wrong? I've created this exact scenario at work many times but, I've never done it with Windows Server 2012. Is this
possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV? I am going to attempt to work on it some more tomorrow when I get over there. I think there may be an issue with the SR-IOV not being enabled on the machine
through the Dell Bios. Would the SR-IOV really cause the workstations to report a slow connection? When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct. I don't
have "ignore slow connections" or any of those GPO's set. I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem. Any help that someone can offer, I am more than willing
to listen. If you need more information, please ask.
Thanks,
Jay

So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
Im disappointed in MS right now.

4.3.2 Upgrade Killed International Roaming

I just upgraded my iPhone 4 to 4.3.2, and it will not connect to GSM networks outside the U.S. (my phone was working on AT&T, but I've been through Japan and Korea today and it won't roam anywhere).
I've played all the idiotic iPhone reset games (power, airplane mode on/off, reset network settings, etc), without any luck. The phone just displays "No Service".
If I attempt to select a carrier, it will display the two local carriers after "Searching...", but as soon as you specifically select one instead of leaving the phone in "Automatic", it will display a message that the signal was lost and return to "No
Has anyone else hit this problem or found a solution? I've seen a few message boards where people are downgrading to version 4.2 and getting roaming back, but I don't have a copy on my Mac and would have to try to backup/downgrade/restore while traveling which I'd prefer to do as a last resort...

My comment in the original post was slightly inaccurate in as much as I stated that my iPad had not been jail broken and this was the issue. I'd forgotten that I had jailbroke the iPad back in IOS 3.1.2 but did a restore the next day after realising that there was little in the jailbreak for me.
A few other posts here indicated that Tinyumberella had an option to go through Cydia when upgrading which i had to uncheck and away it went.
Hope this helps.

Wireless VoIP roaming - getting an 802.11g phone to roam with CCX / CCKM

Hello,
Our group is facing a pretty difficult issue at the moment, we are trying to deploy a wireless Avaya VoIP phone at one of our sites in Australia.
The site in question is located in Western Australia, which is on the other side of the continent to where our 5508 WLC is (in Sydney), so there is a latency of abouy 60-80ms between the sites. When testing the phone at the Sydney location, we're able to authenticate the phone via a number of methods (802.11x, 802.11x FT) and the phone can roam fine. When testing at the WA location, the 802.11x authentication method drops the call when roaming, and the 802.11x FT authentication method has about 2 seconds of dead air during roaming / reassociation.
The avaya phone supports a few different methods of "fast handoff" - CCKM and OKC - and we've only got the OKC (802.11 version of fast transition) method to work, not CCKM. The phone reports error messages when trying to connect to the network with CCKM enabled - specifically "No CCKM AP's" and "No CCX AP's".
So I have some questions...
1) Is a 60ms latency between sites a dealbreaker for wireless voice usually?
2) The voice engineer is convinced that CCX is disabled on the WLAN. My understanding of CCX (according to online Cisco docco) is that it can't be switched off. Is this the case? I know CCKM can be disabled (in the Layer 2 Authentication options) but can CCX or CCKM be enabled / disabled anywhere else?
3) The voice engineer has a point on one front - if we do a command "show ap ccx rm [APName] status", the command outputs "Beacon Request ..... Disabled." This seems to be related to CCX Location awareness - but even after switching this on in the WLC (both globally and for the WLAN), I cannot get this to enable.
3) We have had some minimal success getting the phone to connect with only CCKM Authentication enabled. The phone could not roam. When we did this, I looked at the Client information in the WLC of this device and the CCX Version read "Not Supported." Does this perhaps mean some kind of CCX compatibility problem?
4) Is there much of a difference between OKC (Fast Transition) and CCKM in terms of roaming time? I.e. are we better off trying to install a WLC at the location rather than getting this work remotely.
We're a bit lost on this. Anyone that's had experience in getting Wireless VoIP phones to roam on a wireless campus before, particularly where the WLC is remote, I'd love to hear from you.
Thanks,
Dave

Hi, thanks Steve. Aironet IE is enabled.
The encryption is news to me. We intially tried WPA2/AES & WPA/TKIP together but had no success at all. We then moved to WPA/TKIP, and we were able to get the phone to connect to the WLAN using the CCKM settings, but it doesn't roam at all & the WLC reported the Clients CCX version was "Not Supported".
I think the phone has CCX version 4. Are you certain that the phone will only support WPA & WPA2 with CCX v5? Just that this sounds a little strange, the phone's documentation claims to support CCKM, but if you're right then there's no way we can secure our phone conversations? In previous testing, we did actually temporarily drop all authentication / encryption and the roaming worked perfectly.
Thanks for your help...

Problem with roaming for specific apps

Hi :)
I have a problem with my iPhone 4s:
When i use roaming on my iPhone 4s i try to save some money by turning off roaming for specific apps, but one day for ca. 3 weeks ago it stopped working!
Some apps can use roaming but some can't ;(
There are like 10 apps always turned on, but if i try turning roaming off for an app that is on already it wont work!
If i close settings and reopen it, the app is now denied using roaming!
If i try allowing an app it changes but still wont work and after some time it gets in the same possission i cant change!
I have never experienced this before and i could't find an answer on google ;(
If you know how to fix it please respond to me here :)
~somonekilledme
P.S: Im really sorry if there are bad english here, but im mot english sooooo..... yeah

You are on the right track suspecting DHCP conflicts.
To configure your "roaming network" connect your "slave" Extreme to your main Internet router - either directly or through a switch - and place it in "bridge mode". That will work.
A router will be distributing IP addresses using DHCP. Anything connected to it should be configured as a bridge, the essential difference being that a bridge does not distribute IP addresses.
I do not believe your "slave" Extreme will function connected as it is to the "main" Extreme, but may work if you assign it a static IP address. It is not unusual for it to retain this static IP after having been changed to DHCP if its lease is still valid.
The OK article you referenced must be terribly outdated if it is referring to AirPort Admin Utility. That has not been used in about a decade. Read this one:
Wi-Fi base stations: Extending the range of your wireless network by adding additional Wi-Fi base stations
Unfortunately its screenshots refer to AirPort Utility 5.6, which has been replaced with the prettier, though less useful 6.2.

Do I need a Roaming Network or a Wireless Distribution System?

Hello - as the title says, I am confused about which type of network I should create.
My specs: Macbook Pro
Windows XP Toshiba Laptop
White UFO-shaped Airport Extreme Base Station
New White Square-shaped Airport Extreme Base Station
1 USB HP Deskjet printer
1 Ministack USB hub/external hard drive
1 LaCie USB external hard drive
I am in the process of finishing my basement and will finally have an "office" to place all of my stuff. I want to be able to hook up the USB printer and USB external hard drives at the same time for wireless availability, so I bought the new AEBS. I am concerned about placing the AEBS in the basement and its impact on wireless signal strength to the upper floors of the house, so I thought I would connect the older UFO-shaped AEBS into the system to extend the wireless range.
I am confused, however, about whether to set up a "roaming network" or a "Wireless Distribution System". I am not sure of the particular benefits of either system given my situation so any help someone could provide would be greatly appreciated.
My house is fairly new, and has a data line system to each room, and I have a cable modem and router in the basement and can share the internet connection to the whole house in this manner. My UFO-shaped AEBS was hooked up to the internet connection via this method with an ethernet cable into the back of the AEBS on the main floor of the house. The USB printer was plugged into the UFO-shaped AEBS. This worked well. Again, now that the new AEBS will be in the basement, I am concerned about signal strength, and would like to use my old AEBS to help out.
I have looked at the Designing Airport Extreme 802.11n Networks pdf document and while it is very detailed about how to set up each of these networks, it does not seem to adequately (in my opinion) address why I would choose one setup over another. For example, should I continue to connect the old AEBS to the ethernet wall connection to get internet connectivity, or should the old AEBS receive its connection wirelessly?
Thanks in advance.

I am confused, however, about whether to set up a "roaming network" or a "Wireless Distribution System".
A roaming network uses Ethernet to connect the base stations. Therefore they all transmit good quality wireless data signals. Physically adjacent base stations should be configured to use channels 3 or more apart to reduce interference with each other. Everything gets full bandwidth.
A WDS network connects the base stations via wireless. Therefore the remote and relay base stations can only transmit data with the same quality as they receive it wirelessly. So if a remote station receives a lousy wireless signal from the main base, all of the clients of that remote station will get a lousy data rate. Also each WDS link cuts the available bandwidth in half.
Since your house is already wired for Ethernet, I would use the "roaming network".

Macbook Air 2011 11" - random freezes. Roaming wifi causing it?

I have MacBook Air 11" Mid-2011 (4GB RAM, 128GB SSD, i5). Ever since getting the machine I've experienced random freezes - spinning beachball, screen becomes unresponsive, holding the power button to force it to close being the only thing I can do. The console logs don't show anything that indicates a problem. They just stop logging anything until I restart. I took it to an Apple store Genius while still under warranty and they kept it in for a few days and ran a suite of tests and found nothing.
The problem was completely random and unreproducable. Sometimes it would happen a few times in a row, then nothing for weeks. Also, it was only happening when I was staying in a particular hotel during the week for work. It was Hilton hotel with the wifi being provided by BT Openzone. It would only happen there, never at home, family members house, Starbucks (which also use BT Openzone here in the UK, airports).
I recently made some changes to my home wifi setup and the problem has reappeared, but this time at home. Where previously I just had an Airport Extreme, I have now extended the network over ethernet powerline to a second wifi access point. The second wifi access point has the same SSID as the main network.
All my wireless devices should seamlessly switch between access points as I move them around the house. Our iPhones, iPads and Dell laptop seem to have no problem doing this. When I move away from one access point, once the signal strength drops to certain point, the device connects to the second access point. The MacBook Air also does this, but it seems to freeze if I am in an area where the signals are overlapping. This also describes the situation in the hotel. The BT Openzone hotspots were spread across the hotel. If my room was in an area where the signals from access points were overlapping I would be more likely to experience the freeze.
If I look in the Wifi logs I can see messages stating that some sort of threshold has been reached and the wifi is starting roaming. These messages are always present at the time of the freezes.
Has anyone else experienced this problem? Is it something Apple would fix eventhough I'm now out of warranty? If it could be a hardware problem, would replacing the wifi card myself help?
cheers.

I have MacBook Air 11" Mid-2011 (4GB RAM, 128GB SSD, i5). Ever since getting the machine I've experienced random freezes - spinning beachball, screen becomes unresponsive, holding the power button to force it to close being the only thing I can do. The console logs don't show anything that indicates a problem. They just stop logging anything until I restart. I took it to an Apple store Genius while still under warranty and they kept it in for a few days and ran a suite of tests and found nothing.
The problem was completely random and unreproducable. Sometimes it would happen a few times in a row, then nothing for weeks. Also, it was only happening when I was staying in a particular hotel during the week for work. It was Hilton hotel with the wifi being provided by BT Openzone. It would only happen there, never at home, family members house, Starbucks (which also use BT Openzone here in the UK, airports).
I recently made some changes to my home wifi setup and the problem has reappeared, but this time at home. Where previously I just had an Airport Extreme, I have now extended the network over ethernet powerline to a second wifi access point. The second wifi access point has the same SSID as the main network.
