Lost Connection problem

Hi all, new here
Anyway have had BT Broadband for a couple of years now, had no real issues until Thursday, when we lost connection, I have a HH2 and all the Blue lights were fine, but none of the PC's in the hosue would connect to the hub all of a sudden 1 x desktop, 2 laptops and a netbook, although the net book did connect off and on for about 10 - 15 mins, but only at about 150 to 200k (not 2MB)
spoke to the helpline, went through all the usual tests, and they said in the end the HH was naff, and would order another, thus been without internet since Thursday (This one is at work !)
I did find an old HH v1 (white) on Sunday, plugged that in... same result no connection from any of the pc's, well not for more than about 10 mins max, this make me think it may not have been the hub? if not does nayone have any ideas??
Have changed the filters, and the phone line itself seems clear, BT tested it and said it's all OK

Hi Swills,
Welcome to the forum and thanks for the post.
It seems odd that you are having the same problem with a different router, seems to me that it may not be the router at fault at all. I cant be sure until I run a few checks.
Can you please drop me an email to [email protected], include your BT account details and link to this thread. I will see what I can do.
Cheers

Personal File Sharing: Lost Connection

I'm trying to use my new miniStack external HD attached via Firewire to my Mac mini as a pseudo network drive. In other words, I want that drive available to my mini and my two iBooks. If I can get that working, I'd like it available to my XP box as well.
I have wireless internet via an Airport Express and cable modem throughout the house. All four computers are attached via wireless cards.
I've turned on personal file sharing on the mini using my administrator log in. I've also activated AppleTalk via the Airport settings in the Network preference settings.
I've also activated AppleTalk on my iBook and turned on personal file sharing.
All my Macs are running the latest version of OS X (10.4.7).
I restarted both machines after making the above setting selections. I then used the Finder on my iBook to search for the mini. I clicked on the Network icon, found 'servers', 'library', and the following folders: "home" which has my XP box readily accessible, "My Network" and "Workgroup". Each of these last has an icon for my mini.
When I double click on my Mini, it shows me all volumes on it, including my miniStack. I select one to connect to and get a beach ball followed by an error message saying "Server Connection Interupted: miniStack" and a single button marked 'disconnect'.
After I press the disconnect button (my only choice) I notice that personal file sharing on my mini is now turned off.
This exact same thing happens when I try to access the native internal HD on my mini so it isn't just the external stack that's the problem.
I've searched high and low through the fora here and can't find anything addressing this.
Does anyone have any idea what I'm doing wrong?
Thanks and take care,
Jeff

After much trial and error, I finally resorted to doing a Archive and Install on my mini. After doing so, everything works great. I still have no clue what the problem was but I now have no interest in finding out since it's working great.
Of note, the lost connection problem was unidirectional. I had no difficulties logging onto and accessing anything on either of my iBooks from my mini. Just the other way around.
Take care,
Jeff

My FaceTime won't connect. Every time I try to call my friend it says connecting. Then unable to connect. Or lost connection. And when I go to our FaceTime history it said "FaceTime answered on another device." What can I do to fix this problem?

My FaceTime won't connect. Every time I try to call my friend it says connecting. Then unable to connect. Or lost connection.

Apple has released a document which is reported to address the recent FaceTime issue.

IChat "Lost Connection" | iTunes "-50 Unknown Error Occurred" Problems

Hello Everyone!
Since installing a wireless network in my house my MacBook Pro is having problems. Now, iChat won't connect and just says "Lost connection with AIM" as soon as I attempt to connect, although AOL Instant Messenger works perfectly. Also now when I am trying to purchase music through iTunes it says "-50 Unknown Error Occurred" and it recommends for me to check my network connection. The wireless connection is working fine for internet browsing but I am having all of these troubles with other programs. I am extremely confused. My network is WPA2 Personal, and I'm running 10.4.8. Please help!

Thanks for all the help.

My Philips tv lost Connection to Apple TV 1. Generation After months of no problems: tv says no Videosignal found. Appletv Shows a yellow Blinksignal light on the Front??

Hi all,
My Philips tv lost Connection to Apple TV 1. Generation After months of no problems: tv says no Videosignal found. Appletv Shows a yellow Blinksignal light on the Front??
Can anybody help?

Welcome to the Apple Community.
Restart the Apple TV by removing ALL the cables for 30 seconds.
If this doesn't help then I suspect your Apple TV has failed.

"Lost connection with AIM" error message

Hi all,
I've been a long-time iChat user — I've had very few problems, but now, at home, whenever I've been connected for about 10-15mins, iChat just disconnects with the simple iChat Connect Alert that the app has "Lost connection with AIM. The connection with the host was unexpectedly lost."
My Buddy List collapses to a "disconnected" header and I diappear from my Buddies' buddy lists. If I'm in the middle of a chat (video, audio or text), the chat continues uninterrupted, but I still disappear from people's lists as if I'd disconnected manually. Weird.
The net result is that I have to keep checking to see if I'm connected and then reconnecting all the time. A real pain in the proverbial.
It only happens at the house. My laptop doesn't disconnect if I'm at the office, for instance.
I have cable, coming in to Netgear 814v2 router; out to an 8-port gigabit switch, which then feeds my three main machines. All via ethernet cabling.
All machines have the same problem described above.
I've made the usual Quicktime setting changes.
I've listed the necessary ports in my Mac firewall settings (even though the firewall is turned off).
Each machine has a dedicated IP issued by the router (10.0.0.2 thru 10.0.0.5)
The router firmware is up to date.
What else is there?! I have no problems initiating or joining any sort of chat with my buddies around the world. I have excellent bandwidth. My internet and email are never interrupted 24/7.
Can someone help me? Pretty please?
17" Powerbook G4 & Dual G5 2.5Ghz Mac OS X (10.4.7)

Hi
Try this log on to AIM on port 443 rather than port 5190
Go to IChat > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443.
Log back in again.

NVIDIA OpenGL driver lost connection with the display driver

Alienware M14x Laptop
Windows 7-pre 64-bit
8gb ram
3gb Video: NVIDIA GeForce GT 555M
Intel i7 2760QM
AE CS4
AE keeps crashing. I get the following message while doing something as simple as scrubbing through the timeline, or changing opacity of a layer. in 1080p, I have a picture layer, a solid, some color corrections, and that's it. i just got this new computer and i have never had this problem on my old computer.
this message appears after AE crashes."The NVIDIA OpenGL driver lost connection with the display driver and is unable to continue. The application must close."
this message appears in the taskbar: "Display driver stopped responding and has recovered. Display driver NVIDIA Windows kernel Mode Driver, Version 267.21 stopped responding and has successfully recovered"
any ideas on how to stop AE from causing my display driver to stop working?
Thanks, Ramzi Rebeiz

For anyone picking up this thread (it's probably too late for rrebeiz40 by now!) I have come across a simple but apparently very effective tip that has solved the 'OpenGL driver lost connection' issue for many people using various NVIDIA with various Adobe progs (incidentally a lot of these seem to crop up on Dell machines, especially Notebooks).
(It fixed my issue with Premiere Pro CS4 - GeForce GT 555M on Win 7 Ultimate 64-bit, Dell XPSL702X).
It's posted on http://forum-archive.developer.nvidia.com/index.php?showtopic=5331&st=40 (look for the last post, No 50) as follows:
THIS FIX APPEARS TO WORK...found on an Adobe forum
"This issue led me to this fix: go to NVIDIA Control Panel --> Manage 3D Settings --> Global Settings, and switch "Power Management Mode" to "Prefer Maximum Performance" (the default "Adaptive" setting seemed to be the culprit). And that's it! The key here is changing the "Global" setting, as my individual programs were already set to "Prefer Maximum Performance." I can cause the error to reoccur by changing back to "Adaptive."
Otherwise lots more ideas on this site: http://www.instructables.com/id/How-to-Fix...Nvlddmkm-Error/
My PC has been running for 2 days now. I only put the top fix in for now. Feel happier I have more options if need be though.

It worked for me

Nokia Ovi Suite has lost connection with your devi...

5 months has passed and many hours on the phone to Nokia. The phone has been completely reset /reboot by Nokia time and time again and still the phone gets this message when trying to update software..."Nokia Ovi Suite has lost connection with your device"....We were optimistic that the software upgrade would solve the other problems we are having with all the Nokia phones at work. They are all E52's

Having the same issue currently with an E72 software version is 054.005.266.02 and Ovi Suite 3.1.1.80
Actually I had connection lost all the time with all previous versions of Ovi Suite too... it has never been reliable.
Using original Nokia USB cable, connected securely. Tried different PCs, different USB ports, same issue.
Just now I'm trying software update and it looses connection during the backup process all the time... very disappointing. Screenshot attached if anybody is interested.

E5: Ovi Suite has lost connection with your device...

I am trying to update the software on my E5 using OVI suite but I keep getting an error during the install phase (after backup). The following error and instructions are displayed in the OVI suite window but makes no difference when I follow these instructions (just end up back with the same error).
"Nokia Ovi Suite has lost connection with your device. Follow these steps to help reconnect your device:
1. Remove USB cable from your device.
2. Restart the device (turn off and on again).
3. Re-insert the USB cable.
4. Click 'Ok' below to continue updating."
Current E5 software version is 042.007.
I am trying to update to E5 software v. 043.115
Any ideas?

Yep having the same issue. Just got a replacement handset due to the random restarting issue, soon after setting up the new handset I get a message on phone saying software update is available. Both OVI suite and Nokia software updater say version 43.115 is available (about 200mb in size), I currently have the same version as you 42.007. It claims to do a lot of improvements to the handset. The update downloads fine but when it comes to installing I keep getting the same issue. Phone simply will not restart automatically and the update restarts then fails at the same point over and over. Had the same problem with my previous handset.
I spoke with my network provider to see if it was an issue with the handset needing firmware specific to them but they said no it is an issue with the firmware itself and has been happening to everyone since its release!!! They said I should not download it until Nokia has resolved the issues with it. But how do I know when that will happen as I cannot find anything put out by Nokia stating there is an issue or anywhere on web forums saying there is actually a problem.

'Disk Utility has lost connection with Disk Management Tool' w/ RAID 10 set

Using 4 internal drives, I have specified the following setup for each:
2 partitions, 1 'speed' of 5 GB and 1 'data' of whatever remains.
The 4 speed partitions stripe to a single RAID volume correctly.
The 4 data partitions are used to make a RAID 10 volume as follows:
The first 2 data partitions are mirrored to make a 'data-A'
The next 2 data partitions are mirrored to make a 'data-B'
These complete correctly.
Upon attempting to strip data-A and data-B in order to finish the RAID 10 setup, Disk Utility quits with the following message:
"Disk Utility has lost connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility'.
A search here and on the nets reveals only that this message appeared in 10.3.x when attempting to repair disk permissions and had to do with a rogue iTunes support file. This is occurring on a blank system (no iTunes installed) so I don't think its the same cause.
Note that I was able to complete this setup under Tiger several times without issue, so it seems to be unique to Leopard. Does anyone know what is going on and hopefully suggest a workaround?

To answer my own issue and leave a marker here for others, I was able to successfully set up a RAID 10 partition using diskutil, indicating that the problem is Disk Utility itself and not the RAID implementation.
Disk Utility has proven itself to be bugridden (must restart frequently to get updated view of volumes; drops device names at various times; etc.) and this latest bug would seem to suggest that it should be avoided in favor of diskutil for any serious RAID construction.

Disk Utility has Lost Connection with the Disk Managment Tool

Hi,
For starters, this problem is not associated with the thread that Brian Z. has posted at the top of this forum. Having said that, here's my problem:
I had installed Security Update 2006-003, and Quicktime 7.1. Permissions were repaired before and after each installation, and all went well.
Some hours later, I was experimenting with Apple Remote Desktop. I had activated ARD in the System Preferences>Sharing pane, and it provided me an IP address associated with ARD. I then turned on Airport, and ARD provided me with an IP address associated with that connection. However when I turned off my modem connection, System Preferences>Sharing hung, and had to be Force Quit.
Console Log follows:
===== Mon May 15 2006 ===== 21:09:09 America/Anchorage =====
2006-05-15 21:09:17.488 System Preferences[2732] Can't open input server /Library/InputManagers/Menu Extra Enabler.bundle
2006-05-15 21:09:28.224 System Preferences[2732] ### Error:268435460 File:FileSharing.m Line:308

2006-05-15 21:09:48.415 System Preferences[2732] ### Error:268435460 File:FileSharing.m Line:343
Thinking a plist had become corrupted, I trashed the following:
com.apple.systempreferences.plist
com.apple.RemoteDesktop.plist
com.apple.Remotemanagement.plist
com.apple.sharing.firewall.plist.
System Preferences started out very slowly, but then all the panes except Sharing would work ok.
I booted from the install disk and performed a Disk Repair. There were no problems reported.
When I tried to run a Repair Permissions, after about 20 seconds I got the, "Disk Utility has lost connection with the disk management tool and can not continue. Please quit and relaunch Disk Utility."
I quit D.U. and the Installer, and was able to successfully run a Repair Permissions from the D.U. in my Utilities folder. It had no problems to report.
Continuting to troubleshoot the System Preferences problem, I then trashed the com.apple.preferencepanes.cache. This solved my System Preferences>Sharing problem.
However, I am still unable to perform a Repair Permissions after booting from my install disk (I get the subject message). Repairing permissions from the Disk Utility in my Utilies folder works fine.
Any thoughts out there on a logical way to troubleshoot where my problem is? Is there a way to get a console log when I'm running DU from the install disk, or a comparable source??
Thanks,
Bob

I found this crash log that was generated about the time I had problems with System Preferences hanging.
Thoughts?

Unending connectivity problems -- and Desktop Help...

I'm wasting so much time on connectivity problems that it's positively wearying. Prior to the installation of BT Infinity here in April, I had a low quality broadband service because of the length of the line from the exchange: if I could get a download speed of 1.2Mbps and an upload of a quarter of that, I was doing well.
BT advised that thanks to fibre optic, my Internet should run much faster. So we had Infinity installed. I'm registered with Speedtest.net so am able to see my performance record.
The average download speed is now aroun d 6Mbps and the average upload, more than that at 7Mbps. How an upload speed can consistently be faster than a download escapes me.
But I'm not familiar with the ways of Internet connectivity and try as a I might, can't get my head around it.
This desktop computer runs Vista OS. Vista was **bleep** when it came out and is renowned for its botched handling of Internet connections. So I'm not blaming BT for the literally unending connectivity problems that are occurring now, with line drops, speeds slowing to a crawl, and no guarantee that any connection will last. But it would be good to actually use BT software to help fathom out what's going wrong here, and today's typical morning which looks like this:
1) Boot up computer. Automatic connection to hub via Netgear USB wireless adapter. Hub is on ground floor of this 3-storey property but signal strength from hub is excellent, as confirmed by inSSIDer monitoring, currently showing 54 with no other networks anywhere near that figure.
2) Perhaps 5 minutes after connection established, it's then lost. 'Local Only' is displayed. This is, apparently, a known Vista problem. But Microsoft has issued a fix for it. I know this, because it took 100 hours of ploughin g the Net to find out that MS had finally admitted to one more Vista screw-up. I've used the Microsoft router "fix it" before and it didn't work ("failed to process") so uninstalled it and have DL'd it again now and run it. This time it says it has fixed everything.
3) Computer is re-booted to make the fix effective. Computer connects to Internet. Speedtest.net check yet again confirms that upload speed is faster than download speed.
4) Connection dies. So much for Microsoft Fix It.
5) Windows diagnostics reports that it can re-set the IP profile (or something.) I click yes. The re-set goes through. Connectivity is restored. 10 minutes later, connectivity is lost. Just a red X in the tray. No connection of any kind, not even that daft 'Local Connection' only alert.
6) Reboot. Yet again. BT Desktop Help was installed here and ran OK when we were using our Netgear DSG34 router. But since the change to the BT Hub, the BT program has never run at all. So-oo. . . It has been uninstalled. And then re-DL'd and re-installed. And though the installation has been completed, clicking on 'launch' has failed to launch anything. But anyway. An hour ago, in one of the brief periods today when the Internet connection was holding up, I Revo-ed out the earlier install, DL'd BT desktop Help and re-installed it. . . and I'm still at the same stage as always, with a Firefox browser page that's open and completely blank and has been for the past 30 minutes. The URL is:
file:///C:/Program%20Files/BT%20Broadband%20Desktop%20Help/btbb/Start.html
Repeated page re-loading gets nowhere. Malwarebytes PRO is turned OFF to prevent any possibility of blocking and the antivirus is termporaily SUSPENDED. This PC runs on Windows standard firewall but even turning that OFF doesn't get the page to load. Copying the address into Internet Explorer in case there's a Firefox problem merely results in Firefox being opened and the same blank page running there.
7) After all that. . . Connection lost yet again and this time, Windows cannot connect at all. It reports that the "wireless network security key is not correct". I happen to know that it is, because this is maybe the 20th time it has reported this in the past 10 days and every time I have to key in the "correct" key all over again. . . at which point Windows still says it isn't correct and cannot repair.
Turning off the computer completely, unplugging from the wall, holding in the power switch for a full minute to clear the circuits, traipsing up and dowen three flights of stairs to turn off the hub, then wait, then turn the power back onm again. . . Ah, wot fun times I'm having here with my particular versioin of Infinity (as in, an infinity of connectivcity problems.)
Summary: I seem to be being simultaneously hit with one issue after another.
I'm bewildered as to why ever since Infinity was installed here, my upload speed is generally faster than my download speed. I'm not happy with endless Internet connection failures though am thinking that Vista is playing a large part here with its "wrong security key" and unending 'Local Only / Limited Connection' failures. I do miss my Netgear router and the ability to access a fantastic help menu and re-boot directly from the desktop without having to keep going up and down three flights of sdtairs to do so (I haven't been able to find out how toe access the BT Hub remotely.)
Above all though: I'm really tired of repeatedly trying to run freshly downloaded and installed BT Desktop Help software but getting no further than a blank page because the program has stalled.
If anyone has any advice / suggestions, other than to buy a carrier pigeon, that'd be much appreciated.
Thanks.

Thanks again to John and gg30340. Here's an update:
1) BT Desktop Help removed completely from this computer. The uninstaller itself mopped up everything, which surprised me. But anyway.
2) Bt Home Hub manager set up and working. Had to input serial number and create new password. All of this sounds fairly easy and would be if one had the device near the desk. But the idiots who built this property shoved the BT master socket inside the garage next to the door. Our two home computers are on the third floor. To ensure the wireless signal strength is OK, the Hub and Infinity module/device/whatever it's called are on a high shelf. It's a major job to even reach the darn things, never mind read the labels seeing as how the BT Infinity engineer was good enough to tidy up the cabling and make a very tight connection to the wall socket.
3) I had hoped to be able to back up the Hub's settings, seeing as the software provides for Advanced Settings / System / Backup. But not on mine (Hub 3.0). All that System allows is choosing which internet clock to define the accurate time. Everything else in System is just a pattern of short lines as if trying to indicate that there's some text there but it's invisible.This is now my second encounter with BT software which, for whatever reason, isn't functioning as it should on this PC.
4) Hub reset to factory fresh, according to BT guide.
5) Reset appears to have achieved nothing apart from requiring the password to be popped in again. After reset, it wasn't even possible to connect to the hub manager. Internet connectivity was eventually established for all of 30 seconds and then, gone.
6) Computer was shut down and then booted anew. Internet connectivity is still. . . dreadful. One minute everything's fine and then, literally,. the next minute a webpage won't load. Even opening the Hub Manager has taken three attempts, i.e., disconnecting from the Internet, re-connecting, failing, and trying twice more until success. Yet all the time these failures are occurring, the tray icon is showing a steady, unwavering green icon for Local and Internet access -- despite the fact, there manifestly isn't any.
7) Speedtest. net tests are actually showing upload and download 'trajectories' going slower and slower and finally halting at some point on the arc, then after a period of up to 30 seconds, suddenly becoming animated again. Speed test results with broadband speed checker UK and Think Broadband's checker are so at variance with one another, and with Speedtest, net, that it seems all three are using different technologies in pursuit of the same thing. Either way, upload speeds continue to be much, much faster than download speeds, a state of affairs I certainly have never encountered before.
8) Speedtest net tests taken in the past 10 minutes, with one test following on from its predecessor, begin at 8.24 down/8.88 up, followed by 5.24 down / 6.40 up, followed by a mind-numbingly lonnnnng 0.62 down / 8.70 up -- in other words, a continuous yo-yoin g of Internet connectivity to the pooint that it actually might as well not even be here (I've had to make five attempts just to get on to this forum. . .)
9) BT Speedtest will necessitate disconnection of everything downstairs and all boxes being lugged up here. This is actually going to require uncoililng tied-off cabling and hanging off a stepladder to do so -- though I surely can't be the only person in Britain who doesn't have a nice, handy BT master socket in their study or lounge. That said though: until we switched to Infinity, we *never* experienced these kinds of horrendous connectivity problems and never had need to unplug the Netgear router downstairs and bring it upstairs to connect directly to tjhe desktop PC so BT's own test could be run.
I'll just have to get to work dismantling stuff tomorrow. However, I have to say that after a factory re-set which has changed nothing at all, I'm beginning to think there's a problem with the BT line itself (hence why I'm happy to follow the advice here, though less than happy at the prospect of the messing about involved.)
Thanks, you two, for your patient help, and also for clarifying the situation re the three signal paths being shown on inSSIDer. At least I know that's usual now! And now, hopefully, when I press 'Post', I won't be faced with an endlessly spinning Firefox circle culminating in what may well be, or seem to be, the 57,938th time today of seeing "Page Not Found". . .

Lost connection detection time difference

Having a problem understanding why a broken JDBC connection is detected under Windows much quicker than it is under Linux.
I have an process that opens a connection to MSSQL using JDBC, a Stored Procedure is then executed and the result set
processed, this execute step is repeated every 60 seconds or so. If any exception is thrown then resources are closed, sleep
for 60 seconds, the connection is reopened (if fails then sleeps and repeats), once reopened the process continues. There is logging throughout
the above steps.
On Windows Vista 64bit Sun Java platform the process runs fine, if I deliberately break the connection (stop MSSQL service), the process
logs a problems within 60 seconds and starts handling the error, when the MSSQL comes back then within 60 seonds the connection is remade
and the process continues as expected.
Under Ubuntu 10 64bit both Sun and OpenJDK the process runs fine, until the connectionis broken, as it takes about 17 minutes for the exception to be thrown
for the broken connection (stopped MSSQL) to be detected, as opposed to under Windows taking seconds. Once detected then the process works as expected, retrying
and reconnecting as it should.
The libs and code used are the same the only difference between the windows and linux versions are the logging path parameter, have tried with different versions of Java
and with different MSSQL JDBC drivers.
What could be the reason for the time difference in the lost connection detection between Windows and Linux? Any help tips would be most welcome.
Thanks.

The connection is only made once and used throughout, it is only closed if there is a problem. This runs absolutely fine with logging for weeks, the execute and processing take millisecondsIt is pointless to keep the connection in that situation. Create it every time.
Doing that might even fix your problem. But regardless you should still not keep it.
Have jujst checked the timings and if the db connection is broken the on Linux (Ubuntu) the exception generated by step 4. takes up to 15 minutes 35 seconds to move on to step 7. on Windows though it is instant, there is a log message output prior to the execute statement this outputs then the exeception logged.You have an existing connection.
Then you attempt a request which I am guess takes 17 minutes to timeout. (That happens because you are testing by stopping the server.)
That is the problem.
First verify the connection url. It might have timeout values in it.
If not then the next most likely cause is that someone changed the OS (not java) TCP timeout values. Bad idea if they did. And the only way to fix is to change them back to something reasonable. You can code around this by using two threads. One that sets a timer and the other that runs the request. If the timer fires then attempt to cancel the request (see the jdbc api.)

Repeated lost connections when using WRT54g

Hello everyone.
I have a Lynksys WRT54g v5 and a cable modem, my ISP is Virgin Mobile. Every half an hour or so my internet connection is lost and can only be regained by reseting my modem by turning it on and off. The lost connections appear to occur more frequently when the traffic is heavier. The interuptions occur even when I only have one wired PC connection.
If I connect the PC directly to the modem the connection works fine.
I have already installed the latest firmware, reset to factory settings, tried a MAC address clone as suggested in another thread but nothing has helped.
Is there anything I can try or should I just bin the router?
Thanks for your help!

Version 5 and 6 of this router are of a terrible design. No amount of tweaking, reconfiguration or firmware upgrades will likely help with the disconnect problem. Earlier versions are of a much better design. I had disconnect problems with my version 6 router for over two month which could not be resolved by many attempts through Linksys tech-support. Even replacing it with 2 more version 6 routers did not resolve the disconnect problems which occured 3 or more times a day.
After I changed to a version 3 of the WRT54G the disconnect problem was instantly cured. Version 4 and below or WRT54GL ( which is really a resurrected version4)should work fine.

WiFi Internet connectivity problems after upgrade to 10.8.4

After upgrading to MacOS 10.8.4 I am facing regular interruptions to my WiFi internet connectivity. Periodically the internet connectivity is lost and the only way to fix the problem is to turn WiFi off and on again. This happens frequently when I am downloading files at using big bandwidth (more than 1.5-2 MB/s). If I use assist me on the Network preferences tab, it displays an ISP error when the connectivity is down, however I am certain that I do nota have any kind of ISP or router issue since at the same time I have WiFi internet connectivity from my iPad mini, iPhone 4S and Samsung Galaxy S3. Therefore it should be a 10.8.4 issue
