Frequent loss of 4G connection and inability to reconnect

I have a Pantech UML290 running on a new laptop. Operating system is Windows 7. In my travels I've used my system in various areas listed as having 4G with no appreciable difference in performance. Have had ongoing problems with maintaining connection and ongoing difficulty reestablishing a connection once lost. Shortly after computer boot up or the first time trying to connect after having been operating for a while, a connection is frequently established in less than a minute. If I try to reestablish after having lost a connection I get a device not available error or if not that, it may go off and think about connecting for many minutes or even more than an hour before finally connecting, if it does. Pretty consistently, if I reboot, I can reestablish a connection in seconds. Not at all convenient to have to reboot... I have spent substantial time on the phone with tech support, swapped out the modem, and in general been disappointed in the reliability of this system. I previously had a 3G modem that was rock solid and reliable and was very satisfied with its performance. A few weeks back I accepted the popup to check for updates and access manager went through an update including firmware update to the modem. After the update the system would not connect at all and repeatedly gave the device not available error (an error # tech support doesn't seem to be familiar with). I did look in my notes for the error number to include here to no avail... I managed to uninstall the update and located an earlier version of access manager (ver 7.6.3.4 (2642j) which has run reasonably well since. This lack or reliability/predictability is a real problem as I use this for business. Just got another notice to update. Any suggestions.

TC & MBP - complete loss of wireless connection and usage

I apologise in advance if this is a very long winded post! I've been an Apple fan for some 20 years now and it's only in the last three months that my love affair is starting to wane due to (what seems to me) poor hardware releases.
My setup:
1 x PowerBook G4 1.25Ghz with Edimax 802.11n PC Card
1 x MBP 2.4Ghz (purchased April 2008) with AirPort 802.11n
1 x Time Capsule 500Gb
1 x Airport Extreme Base Station Gigabit Ethernet edition
1 x Netgear DG384 v2 (wired only) modem router
1 x standard ADSL connection (8Mbps) from a UK ISP (and yes, 8Mb is about the norm for the UK! Though in reality, it means closer to 4Mb...)
The Netgear router is connected to the ADSL line and is set up as the DHCP server for the network. I have a Fixed IP address from my ISP. The Time Capsule is connected via ethernet to the Netgear router. The TC is set up in Bridge mode as the router serves DHCP. The TC is wall mounted via the excellent AirMount from H-Squared.
The TC has been through a myriad of configurations in an attempt to create a stable wireless environment since its purchase in April. Prior to my recent holiday (two weeks in Greece - hurrah!), the current configuration was solid for both Macs.
The config is: Bridge mode; 2.4Ghz N Only wireless; WPA2 secured; no MAC address access control restrictions (so pretty straightforward). The TC is running firmware 7.3.1. It is setup as "Create a Wireless Network"
Both Macs are running OS X 10.5.3 with all of the latest updates including AirPort Utility 5.3.2.
It took me about six weeks to hit upon this config for the TC having had many wireless drop outs, stalled connections, lost internet connections (ie. I could access the TC HDD but could not access the internet using the same wireless connection). So much frustration in the early days - I tried many of the solutions on this forum but to no avail until I hit upon the 2.4Ghz N Only route which seemed to be the answer to all my problems.
Prior to leaving on holiday, I unplugged all of the equipment in the room including the TC and the router. When I returned, I restarted everything in a logical sequence - router first (and waited for a connection), then the TC and then the Macs.
From this point on the problems have started. The PB G4 with the wireless card has a more or less stable connection. The wireless card connects immediately to the TC but then it takes approximately 30-60 seconds for an internet connection to work (so I see a lot of the Not connected to the internet messages in Safari). It seems to immediately get an IP address from the router via the TC but then the internet connection itself takes a while to come up.
The MPB on the other hand is a nightmare. Since returning from holiday I have not been able to get a workable wireless connection at all. In no particular order, the problems that the MBP exhibits are as follows (these can occur at the same time or individually):
i) only returns a self-assigned IP address; renewing the DHCP lease does not fix the problem
ii) does not see the network at all (although it will see others in the vicinity)
iii) cannot connect to the network - returns the Connection Timeout error or very occasionally the Password Incorrect error; I have tried connecting the network via the AirPort menu bar item, via Join another network... from the menu bar, via the Network selection menu in System Preferences > Network and even via Internet Connect - all with no success
iv) sometimes I am able to connect to the network but no IP address is received. Having checked the TC logs, it shows the same error occurring over and over again:
Jun 26 22:06:04 Severity:5 Associated with station 00:1e:c2:ba:78:6c
Jun 26 22:06:07 Severity:5 Deauthenticating with station 00:1e:c2:ba:78:6c (reserved 2).
Jun 26 22:06:07 Severity:5 Disassociated with station 00:1e:c2:ba:78:6c
The MBP connects but is immediately thrown off the network.
So to all intents and purposes, the wireless aspect of the MBP and the TC are completely useless.
When I use a wired (ethernet) connection to the TC everything is joyful. Instant IP address assignment, excellent connection speeds, no drop outs and so on. So as far as I can ascertain, the TC is working fine with the exception of the wireless/wireless security.
The AEBSn that is connected to the same network no longer appears in Airport Utility.
Having read through many posts here, I have tried many solutions including:
- downgrading the FW to 7.3; no difference at all
- turning off wireless security; no difference at all
- changing channels; I've tried 1, 6, 9, 11 and 13 with no difference at all
- changing the wireless mode; B/G, G only, N only all make no difference (I can't use 5Ghz N only as the PB G4 does not support this and I need both Macs wirelessly connected)
- rebooting the TC (both via Airport Utility and 'power off'); makes no difference
- reinstalled OS X 10.5.1 (via the install disks that came with the MBP) using the Archive & Install feature; then used the Combo updater to upgrade directly to 10.5.3; once again, no difference.
I have not yet done a hard reset as this has made no difference in the past but obviously I will try it.
In other words, HELP!
I am stymied. I have tried so many solutions offered on here and on the likes of MacFixIt and other Mac forums none of which have brought back my wireless connection for the MBP.
The MBP works very well with other wireless connection. For example, at work, we have a Linksys WRT54G wireless router connected to a BT leased line. I have not had a single connection issue for three months with this setup. Similarly, whilst on holiday, I used many different hot spots and had no issues with the wireless connection. All of this evidence leads me to suspect that the MBP is not the issue.
From what I can tell, the problem seems to be in the wireless security on the TC. It seems to prevent access by MBP (though not the PB G4 using a wireless card) but disabling security did not change the error messages shown in the log or the lack of connectivity.
It is a real shame that I cannot get a satisfactory working environment with the TC as the concept is great. The reality is, however, that it is unusable in its current condition and loathe as I am to try and return it or replace it, I am rapidly coming the conclusion I will have to.
Before I do, however, I am hoping that the genii who exist on these forums may be able to proffer some ideas or solutions that I haven't yet tried.
My sincere thanks will go to anyone who provides a solution for me. There may even be beer involved as a mark of gratitude!!
Thanks for reading and fingers crossed someone knows something special...

Smokerz: thanks for the reply and the advice. Not really in a position to set up a dual network at the moment due to the positioning of the TC and the AEBS but if I get an opportunity to try it I will.
I have temporarily given up with the TC as the router for the wireless network. I've installed a Vigor 2820n modem router (it's the only one I could find that has a Gigabit port - only one though) as well being a modem (ADSL) router. Thus far, everything seems fine - although I have had a couple of drop outs due (I think) the AirPort connection on the MBP. And interestingly, I've set up the TC as a "test" wireless network using the Vigor's internet connection and it's way more stable than with the Netgear router. So perhaps it's a combination of many factors - the poor Netgear router, the TC and the MBP AirPort connection - that was causing the issues.
I'll give 10.5.4 a go as well and see if that helps at all.
Thanks to all who read the question - if anyone else has thoughts I'd be delighted to hear them.

Frequent loss of internet connection has me stumped ideas anyone???

I have an almost new 24" Imac and I have been having connection issues recently with Comcast and I am going, no wait am insane. I had a Belkin router that was going flaky and got a new one but it was worse than the old one and after trying no router for a week and no lost connections I bought a Linksys and it was great for about 3 weeks and then suddenly loss of connection again. I used to have both a G4 QS733 and also an Intel Mini that had similar problems, the Mini was so bad in fact I ended up exchanging and selling the new on Ebay without even opening it up. I have replaced EVERYTHING in the past year startiing at the pole every cable and ethernet cable as well as the modem and the router (3x on that) and the computer has been changed out. I noticed when this happens my pc is still able to connect which makes it even worse because it all leads back to the apple being the problem. I noticed the problem returned a few days ago and I think it was right after a bunch of updates ( I currently am running 10.4.10) so maybe that is the problem??? Just seems weird to have a total of 8, yes 8 macs have the exact same problem but I have had about 40 different pc based laptops hooked to the same connection at various times and NONE had a problem. I get the feeling this is a simple incompatibilty issue between the Apple and the routers but I am out of ideas.
24" iMac 400 Pismo Panasonic Toughbook cf-28 for work Mac OS X (10.4.9)

Hi Tim Hartzell!
I may be off-base here, and my apologies if so, but I have a feeling you're having exactly the same connection issue with each of your Macs, not because they are not compatible, because they are in fact compatible, but due to misunderstanding how to perform one particular step of the initial setup of the Mac. This comment is not meant to slight you, as at one point I did EXACTLY the same thing and had the same results (I once used Comcast), and that's why I'm answering your question.
This isn't unusual if during setup of a Mac (the Welcome! procedure/program) you incorrectly identify and answer the question at the top of one particular page in the setup process:
"How Do You Connect to the Internet?"
Recall that one?
The question means how does your Mac connect - not how does your network connect. Therefore, if you are connected to Comcast via a cable modem, then have a router wired to it, and your Mac wired to the router with an ethernet cable, the answer should be:
"I connect to my local area network (LAN)."
You should NOT answer: "I use a cable modem to connect to the Internet."
If your ever change your Mac's connection back so that it is no longer connected to your network, but is instead connected directly to the cable modem, you'll find the same issue in reverse, and you'll have to reconfigure by answering with: "I use a cable modem to connect to the Internet."
The good news is that there's an easy fix, and you don't have to dig out the Install Discs and re-install your OS to fix your problem, nor do you reconfigure all your settings each time you change your connection method. Simply:
Open System Preferences, open the Network panel, click on the "Assist me..." button at the bottom of the panel, followed by clicking the blue "Assistant..." button in the drop-down box. [Do NOT click the "Diagnostics..." button.]
"Network Setup Assistant" will open while System Preferences will remain open behind it. On the "Introduction" pane, for convenience enter "ethernet to router" in the "Location Name:" box and click the "Continue" button. On the "How Do You Connect to the Internet?" pane, activate (by clicking) the radio button left of "I connect to my local area network (LAN)." and then click the "Continue" button.
Read and proceed. After configuration is completed you will see in bold at the top "Congratulations! You Are Connected." Click the "Done" button and Network Setup Assistant will close and quit. There should be a message box in front of System Preferences stating that "Your network settings have been changed by another application." That's as it should be, since you just used another app to make those changes, so click "OK" and close.
Finally, change the "Show:" selector to "Network Port Configurations" and select (highlight) the line "Built-in Ethernet" and simply use the mouse to drag the entire line to the top of the list. If you use wireless to connect to a printer, move "AirPort" into second position on the list, and follow by clicking the "Apply Now" button at bottom right.
The above will change none of the previous settings in other configurations that are maintained in the Network panel of System Preferences. The name of each of those different configurations is displayed in the "Location:" selector for you to choose how you wish to be connected. You should now see on that selector the name you earlier gave this new configuration - "ethernet to router"
While it may appear to be confusing, you'll notice that after you switch from one configuration name to another and have clicked the "Apply Now" button - the settings that you will see on each pane will be the ones that are appropriate for that configuration. That means that if you want to connect directly to your cable modem again, bypassing your router and your network, you'll need to change the "Location:" selector back from "ethernet to router" to whatever the current setting is called, followed by clicking the "Apply Now" button.
Once you have a working configuration, be careful not to edit any of its particular settings followed by clicking the "Apply Now" button, as that will alter the configuration so that it may no longer work.
Rather than haphazardly editing a working configuration, it's less confusing to simply initiate an entirely new configuration, as you've just done above. If that would then continue to work better for you, say for a month or so, then the prior configuration, and other old configurations, may no longer be necessary, and can be deleted from the "Location:" selector.

Frequent loss of internet connection

Here's the situation, hope someone can help.
We have four Macs in the house, all accessing the internet (at various times) through a Linksys wireless router. We have no difficulties with internet access on the iBook G4, MacBook, or MacBook Pro. Our iMac G4, over the past few months, has had an increasingly frequent problem with the internet connection dropping out.
The issue is intermittent and unpredictable. At times, we used to be able to surf for an hour or two with no problem. Other times, we wake the computer up and it will not connect. Yet other times, it will work for five or ten or twenty minutes then drop out completely. The most frequent scenario is the internet connection working for fifteen or twenty minutes then dropping out. The problem is becoming more frequent. In the past week or so, we have been unable to use the iMac on the internet for more than a half hour or so without losing the connection.
When the internet drops out, the airport icon on the menu bar shows a connection to the router. If we run the network diagnostics, everything is green except for the actual connection to the internet. The laptops can access the internet through the same router without issue when the iMac has lost internet access.
When the problem first appeared, we could turn Airport off and then on and the internet connection would come back. That has stopped working. A few times, running through the network diagnostics has done something (??) and the connection resumes. This morning, I had to restart the computer to get the connection back. I am to the point of praying over it while randomly clicking on diagnostic-looking buttons. I'm thinking about waving a chicken over it while chanting something as my next trick. Sadly, I am the most Mac-adept person in the house.
We have reset and/or restarted the modem with no luck. We have plenty of disk space left. Everything else on the computer works fine. When the iMac can access the internet, it works great. I added memory and upgraded to Leopard within the past year.
Given that the iMac shows a good connection to the router, I don't think that is the problem. Given that the other computers can surf happily while the iMac can't suggests it isn't a problem with the internet connection itself. I truly have no idea where to look or what to try.
Can someone please please please help? I've always had such good luck on these forums. I am at wits end and am dealing with some frustrated folks here in the house.
Thank you!!
Deanna

Hi,
Our iMac G4, over the past few months, has had an increasingly frequent problem with the internet connection dropping out.
Try changing the G5 Airport channel.
Open AirPort Utility (Applications/Utilities)
Select the device you’re setting up on the elft and then click Manual Setup. Enter the base station password if necessary.
Click AirPort in the toolbar, and then click Wireless.
Choose a new channel from the Channel pop-up menu.
If that doesn't help, go to /Library/Preferences. Move all the files in the System Configuration folder to the Trash, restart the G4.

Loss of DNS connection and internet access to camera

I seemed to have lost my connection after a power outage last week. I've reconfigured the camera several times and it still seems to lose it's settings (date, static IP) I've checked the port forward settings which are fine. I see the camera on my PC utility and within my network. There is also a error on the camera that it hasn't been able to contact the DDNS server on it's scheduled updates. Any suggestions. I'm using the Linksys router WRT54GX2.

Hi....
As you are losing the settings on the camera i would like u to upgrade the camera firmware.
Also upgrade the router firmware.
After upgrading the camera and the router firmware, reset the devices and then reconfigure it.
After reconfiguring the camera, login into the camera setup page, go to setup and then sololink DDNS and click on Update now.
Check whether you are able to access the camera remotely.

Alot of ppl are experiencing this issue as well as me. I though this issue would have been fixed after the new update but it certainly didnt. Apple needs to resolve this quickly

Re: poor connectivity and speed with new comcast gateway

Welcome to the wonderfulo world of Comcast. I have been paying for the 50Mb service for over two years. It has never exceeded 23Mb in any speed test, but Comcast wants to charge more if I change to the 25Mb tier. Now we get a notice of up to 75Mb and find that the speed tests show no improvement whatsoever. Conversation with two Comcast installers in the past indicate that in my area we will never see anything above 25Mb. As for the gateway, in two years I have changed the hardware three times and it has made no difference. There is frequent loss of WiFi connection and poor speed whether WiFo or ethernet cable connection is used. Unfortunately, there are few options to address the situation. One is to purchase your own cable compatible modem (Comcast has a list of the ones they say will work) and fight with the company to get the service bill adjusted to reflect the nonuse of their equipment. The other option (short of waiting for Google fiber to go active) is to join the masses that are filing complaints with the FCC, forcing Comcast to address a variety of problems.

It's not normal to get less than advetised speeds. Generally you should be seeing speeds slightly faster than advertised. Any tech that told you Comcast's sytem was not capable of more than 25MBps was not knowledgable.

2012 MacBook Pro Intel i7 (purchased May 2013) constantly drops airport connection. My 2006 MacBook Pro has no problems connecting and staying connected.

I received a 2012 MacBook Pro INtel i7 for my birthday this May 2013. It constantly drops my airport connection. My ancient 2006 MacBook Pro has no problem connecting to airport, nor staying connected. I've had to write this message several times as I keep losing the airport connection and have to reconnect. BTW: I am less than five feet from the airport base.
Thanks for help.

After trying all of the above the suggestions, the problem returned as before. However, after digging some more I discovered that the issue appears to lie with the 10.4.10 version of the Mac OS; when I checked the software log under the system profiler I noticed that I had installed that update at about the time my Airport problems began. Apple then quietly released a v 1.1 combo update to 10.4.10 on July 2nd, which once installed appears to have resolved the problem. You can find the download at http://www.apple.com/support/downloads/macosx10410comboupdatev11intel.html
What's curious is that originally Apple listed that the v 1.1 combo update resolved some issues with RAW image data, and some sound problems, which don't seem to have anything to do with Airport.

What are possible causes for frequent loss of wireless mouse connectivity other than the batteries ?

Wi-Fi or another interference source. Try turning off the Wi-Fi and see if the problems continue. If that solves the problem, see if you can set your Wi-Fi to run in the 5 GHz range.

Check your Bluetooth, do you have a bunch of stuff listed in there that you are no longer using?
Or another peripheral you stored away in a cabinet near by?

My airport express frequently drops the internet connection. Once I unplug it and re-plug it in, everything is fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

It is tricky..
But yes it can be done as long as you use a different IP subnet to what is being used for the internet..
So I need to know what modem router you have?? Does it have wireless as that would make it very easy?
What IP is the computer getting?
Then I can give you the details to setup wireless statically on a different subnet.

Unexpected shutdowns and loss of internet connectivity on brand new 420t

Hi,
I was experiencing unexpected shutdowns (would see safe mode choices when turned PC back on) and also intermittent internet connectivity issues.
To Fix:
In device manager, I turned off the option in the Realtek Network Controller Power management tab to allow the computer to turn off this device to save power.
It's been working like a charm so far (2 days). I'm not so sure HP should be building PCs with this option set. There are no updates that I haven't installed either. PC still sleeps (can see nic lights go off) and wakes up just fine.
Other that that we really like this PC...Beats Audio wasn't impressive with only the internal speakers, then I tried a good set of external tweeters and a subwoofer and then it was realized.
Hope this helps someone.

Troy,
Thanks for the suggestion. It sounds like you've heard that others have had this problem. Is that right?
And are you suggesting that the kernel panics and the loss of Internet connection are related? They often happen independently of one another.
