Loss of wireless connection

I've completely lost my wireless connection to my home hub although I can connect through an ethernet cable. I can connect to a wi fi hotspot. This has happened before and phoning the helpline has got it working again. This time I was told I need a new router and would get one if I renewed my contract. As a 10 yr customer I wasn't happy! If I refresh the network list, my home hub is there but the connect failure message mentions TCP/IP is not configured although settings of my adapter say it is. I've tried another router but exactly the same thing happens. This is also the scenario on the stepsons macbook. Any thoughts?

There is some help on this page.

Detect loss of wireless connection

GOAL : physicians in a hospital getting access to web-based JSP content through a Pocket PC browser(IE) and wireless connectivity. We already have the "normal-size" JSP pages for desktop computers and we'd like just to provide a reduced version of theses pages to browse on a PDA.
PROBLEM : Even with a well designed WLAN with good access point placement, you may experience connection loss. And it's a problem when browsing JSP pages : imagine submitting a form when you're suddenly offline : you'll get a 404 or something similar -> not serious.
QUESTION : If I port our application in the Personal Profile Xlet framework, Would it be possible to detect connection loss in an Xlet or somewhat... then it could set the rest of the app to work in a kind of degraded mode. How can we manage that ?

You could have a thread which is dedicated to managing the apparent connectivity. It connects to a well known location, if it cannot connect then you are assumed to be disconnected and the application should downgrade. The routines that handle networking should be able to fail gracefully and not generate exceptions which would terminate the program. As an example you can update your stocks whenever theres a connection but if there isn't one you can always show the value and the last time it was successfully retrieved.

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.

Loss of wireless connection with 350n

I am having a terrible time with loss of connection with my 350 N wireless router. The router itself is on top of a bookshelf less than 50 feet away from both of my wireless desktops, and faces straight down the hallway that both rooms the computers are in open from. Often when I start up my computer it refuses to acknowledge that there is a wireless network present in the house and the only way I can make it detect it is if I powercyle the router--which is a pain. Even sitting directly next to the router it will never recognize better than 85% signal strength. And when I load (not play, just initiate loading) download-heavy content such as streaming video or an MMORPG program the connection will often drop and then reconnect seconds later. Upon performing a speed test it unfailingly indicates that my upstream is twice as fast as my downstream, which reads at only around 1165 Mbps--which is absurd as my modem is provisioned for and often surpasses 16000Mbps. What on earth is going on and what can I do to overcome it? I'm getting desperate here.

I have fixed my problem by upgrading the router firmware to version 1.03.7 from version 1.03.5.
The issue I had upgrading the router was it would fail at about 80% when using the router to do the upgrade soooooo, this is how I did it ( stolen from another thread )
Be warned! If you do the below and you have custom setting on the router you need to write those setting down first!!!!!!
1. Download tftp.exe using this link (ftp://ftp.linksys.com/pub/network/tftp.exe)
2. Download the new firmware (version 1.03.7) at Linksys download site
3. Reset your router by pushing and holding the reset button in the rear for 30sec
4. Configure a static IP address (192.168.1.50 with Subnet Mask 255.255.255.0) on YOUR PC
5. Connect a network cable from your PC to your router
6. Test that your PC is talking to the router by openning a DOS window and type "ping 192.168.1.1" (without the paranthesis) and you should get 3 replies.
7. Double click on the tftp.exe
8. Type in the IP Address for the Server: 192.168.1.1
9. Password is "password" (WITHOUT the paranthesis)
10. For the BIN file, click on the square-button and browse to the BIN file that you've downloaded from the LinkSys Site (WRT350N_1.03.7_US_code.bin)
11. Click on Upgrade
12. After the upgrade is successful, perform the reset, again. IMPORTANT!!!! PUSH AND HOLD THE RESET BUTTON FOR 30sec then let go.
13. POWER light should be blinking during boot up then stay SOLID
14. Now, change YOUR PC IP seeting back to what they were before you started this process.
15. Start InternetExploder and surf the net
16. GOODLUCK!!!
As soon as I did this, my laptop wireless started working 100% and right away.

Loss of Wireless Connectivity

Hello Everyone,
I am having a major problem with my wireless network. At random intervals, I notice my wireless network speed (54mbps) slowly decrease from 54 -> 48 -> down to -> 4 -> 2 -> 1 -> dies. My wireless router then goes off for anywhere between 10s to 10 minutes, or sometimes it can even be down for 45 minutes.
I've encountered this ever since I moved my PC from across my room, though I believe it happened rarely before hand as well. Ive since tried using programs to determine the best connection (which Ive finally achieved). Also due to the building, I cannot run a wired line to my computer. My computer sits about 25-30 feet away from the router, almost a 45 degree angle above it (2nd floor, router access point is on the 1st).
Another note: Its not just my personal computer that loses wireless, the entire network dies at the same time. Though, the WIRED network that is connected to the router receives no interuption. I have exchange students that board at my house from time to time, along with the other main computer that resides in the room with the router, and neither receive connection hiccups or loss of network bandwidth. Also during this time my Wireless PCI card in my tower can still detect other networks (though very weak due to range)
As a thought, my router was about 2 years old, so I recently upgraded it from WRT54G to a WRT300N. The issue is just as frequent.
As for specifics:
Network:
Old Router: WRT54G (2 1/2 years old)
New Router: WRT300N
-- Router runs WEP encrypt, Ive recently turned off MAC filtering, tested both Channel 1 and Channel 10 (6 is overloaded with 2-3 other routers in the area).
Wiress PCI Card: WMP54GS (90% sure I have the Speedbooster Version)
-- My PCI card has a 7db antenna attached on a 1.5m chord.
Cable Modem (About 8 years old, unfortunately)
Computer Setup
Windows XP Pro 32bit
ZoneAlarm Firewall / AVG Virus Scanner
Intel Quadcore @ 2.4ghz / 2gb Ram @1066 / Dual Harddrives
Side Note: I live about 100-200 metres away from a Canadian Forces Naval Base. I hadn't had any major connection issues prior to moving my computer 16 feet over to the other corner of my room, but unsure if military base could provide wireless interuptions as Im describing.
The only other thing I can think of at this time is range, as Ive gotten my connection down to a 30 based Signal to Noise ratio (Used Netstumbler to determine)
Also plan to upgrade my PCI card to N shortly, though depending.
Any thoughts or help would be greatly appreciated! Thank you!

I cannot confirm that other Wireless routers in my area share this same issue. I haven't tried to update firmware yet, as from the few I had talked to you generally don't want to touch something like that until a last resort.
I use a program called "Netstumbler" to detect other networks around me. As best as I can tell, when my router disappears off the grid, a lot of other routers do as well. I've used Channel 1 on G frequencies because the average number is as follows:
Channels:
1 - 1 person (me)
6 - 4 people (unknown)
11 - 1 person (close neighbour).
As to which neighbours are using wirless routers, Im unsure. About 30 meters away from my router, as mine unfortunately is placed agaisnt the house wall, is a complex that houses about 20-25 families. My computer also shares the same wall, but a floor above (like stated) for connectivity.
As for firmware, I believe I'll have a look into which Im running and hopefully update. I think it might not hurt even looking into an update for my PCI card as well.
Anymore help regarding this issue is appreciated. Thank you

My mac is causing loss of wireless connectivity on pc's

Okay so i have a new macbook and the airport card appears to be working fine. my friend has a new sony vaio. I can connect to their wireless network just fine, but for some reason, when i connect, even if it turn air port off, the vaio will not connect to the wireless network. It recognizes the network and shows full signal strength, but reports that there is limited connectivity and will not browse the internet. I have tried a lot of things such as restarting the viao, disconnecting and reconnecting to the network, but the only thing that seems to work is to unplug the wireless router and then plug everything back in. Does anyone know of a reason air port would cause this type of interference? Thank you so much!

Sudden slowness and loss of wireless connection to PC

I've used my Dell laptop on my Airport Extreme wireless network without problem for two years. Yesterday, after installing an HP 8500 printer on the network, my PC became extraordinarily slow on the network, and kept losing its connection. I haven't been able to get it fixed. I've reinstalled the airport extreme, I've reset the cable modem and have turned my firewall off, but nothing has worked. I also uninstalled the printer, but that didn't help either. Any ideas for other things I can try? The imac and iphones connected to this network are still functioning fine, as is the printer, which I've now re-installed. It's just my Dell laptop that is not. Oh, btw, I took the laptop to a wireless hotspot this afternoon, and had no problem connecting to that network.

Update: Reverted to firmware version 7.4.2 and the problem was instantly solved. Hallelujah!

Update to 10.5.2 caused loss of wireless connectivity

After updating from 10.5.1 to 10.5.2 I couldn't connect to Network (wireless). Router function checked out ok with ISP. (I could get online wirelessly with my PDA.) I could get connectivity with my MBP via ethernet cable. I also couldn't connect wirelessly to my printer (which I could do before). Spent a lot of time with AppleCare tech. but didn't solve anything. Wound up reloading OS and restoring w/Time Machine. I'm back to v.10.5, and all works well. I'm reluctant to upgrade to anything further at the moment (maybe to 10.5.1...?). I'm concerned that I'll wind up with the same problem if I go up to 10.5.2. Any thoughts where I should go from here?

I'm "replying" to my own message because I need to modify it! With v.10.5 that I wound up with, I lost functionality of iTunes, plus a couple of other apps. Feeling masochistic, I then updated (again!) to 10.5.2. The various functions are back working fine, but AirPort cannot connect. I therefore connected my MBP to the router with an ethernet cable. Everything works OK, but it would sure be nice to function wirelessly like I did before the update! Any suggestions would be appreciated. BTW, on my system, I have Parallels and WinXP, but I haven't used it in several weeks; might there be some sort of conflict there, even if I'm not using Parallels?

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

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.

Loss of wireless radio control via Fn+F5 - without Access Connections

Hi everyone,
I run Windows XP on my X41. I do not have Access Connections installed, and I do not wish to install it. I have recently updated my wireless drivers, and have since lost the ability to control the power settings via Fn+F5. When I press Fn+F5, the following is displayed:
Change Power Settings of Wireless Radios
Unable to change power state of 802.11 Wireless Radio.
Update the driver for the wireless adapter.
I have removed and re-installed the hotkey, wifi and power management software, to no avail.
Any help would be welcome.
Also, can anyone explain what the different utilities that come with the Intel PROSet achieve? Specifically, WMI support.
Thanks in advance.
X41 1.5GB RAM (Looking for a cheap 1.8" SSD or CF solution)

Hi, in my experience you need the ProSet portion of the Wireless driver installed to activate the Fn+F5 functionality. Installing the ProSet provides the AEGIS protocol for the wireless card.
If you check in the Properties of the Wireless card (through Control Panel>>Network Connections and right click the wireless connection) you should see the AEGIS protocol in the item list of the 'General' tab. If the protocol is not present try running the ProSet install of the wireless driver, and check the protocol is present, and this should fix the problem of Fn+F5.
Hope this helps.

Wireless connection loss after sleep

Hello,
I seem to lose my wireless connections upon awakening from sleep mode. Whereas in the past after waking up it would stay connected. Any help is much appreciated.

James, welcome to the discussions!
Check the following settings:
System Preferences > Network. Click on the gear shaped icon below the connection list on the left and select Set Service Order. Make sure your AirPort connection is at the top of the list. If ethernet is at the top, your Mac will look for ethernet connections first before looking for a wireless connection.
Return to the Network page and click the Airport connection to highlight it. Then click Advanced at the lower right of the pane. Make sure your wireless network is at the top of the list of networks. If it's not, you can drag it to the top so it's first in line to connect. Delete any old networks you do not need by clicking the - (minus) button.
Make sure there is a check mark next to "remember any networks this computer has joined". There should not be a check mark on the next two settings.

Mystery loss of wireless internet connection??

As of last night, I've suddenly lost my internet connection (getting the error message when logging into Safari "could not open ...... because the server could not be found"). I have a standard airport card installed into my G4 Imac (no basestation) and I'm running a wireless connection to a Netgear modem which is shared with another computer in my flat. I havent made any changes as far as i'm aware although i suspiciously lost the connection shortly after using Limewire for a brief period. I'm guessing theres some settings that need to be fiddled with in the network or sharing menus within the system prefs. I'm very concerned as i dont really know any mac-friendly people that would be able to physically take a look at the problem.
When it comes to the technical side of computers, I'm not the best so i'm hoping someone can assist me on this. I'm corncerned about altering settings without assistance incase i deepen the problem. Please help!!!

Another user reported that his connection problem was solved when he set his Linksys router to b mode only.

HP 8600 OfficeJet continues to lose wireless connection

Hello - I just purchased this printer for the purpose of wireless printing from my iPad, iMac, iPhone, and the fact that the old HP was several years old and beginning to not work correctly. So the Windows Xp is also a factor in printing. The iPad, iMac, and iPhone did recognize the printer the first time and printed what I sent as a test. I read through the set up that is quite simple. The first time every device connected and was able to print to the printer. I even set up emails that would be used to send to the printer when I am away. This all tested out correctly. It is a secure network (entered my SSID key that was accepted) and if I have to use this printer on an unsecure network I'll take it back to the store. **** The very next day nothing worked because the printer lost the wireless connection. I went through the set up again to re-establish the connection. That worked fine. **** Even still the next day after doing all of that the printer was again not printing because it was not recognizing the wireless. I tried numerous things and as of this posting the printer will not work wirelessly or USB connected. I rebooted the router, computer (Windows xp), and printer. I went through the install again and the printer says it's connected. I do notice that the 'fan' that shows the wireless (blue light at bottom right) is off but the blue light is on. The power button light also flickers off and on. So, back to running all the set up and re-installs. I did this several times and pulled the USB plug when instructed by the set up. Still nothing. I also went through the printer to do the troubleshooting that the help suggests and the displays and reports are showing nothing that says the printer is not connected. The report actually says the wireless connection is working. None of the other devices that are wireless have ever had a problem on this router. Those work just fine. I read through this forum and didn't see anything that looked like the problem I am experiencing. What next? Thank you Daria This is the set up: Hp Officejet 8600 wireless printer Windows XP SP3 DirectTV DSL wireless router

It seems that any little glitch, power loss, no paper etc, causes a major search on how to restore my HP Officejet Pro 8600 to wireless internet connectivity. (Networked with IMac and another PC with windows)Is there a reason that this happens and therefore a standard correction?

Loss of internet connectivity after upgrading to windows 8.1

Hi, After upgrading to windows 8.1 from windows 8 i am experiencing major problems , loss of internet connectivity for no reason both I.E. and G/CHROME are now taking an age to open there are no virus issues as far as i can see.
I have uninstalled and re-installed windows 8.1 about four times over the past 9 months or so and the same thing happens after all the updates are in it runs like a dream for say 6weeks or so then i get the same faults as described above then i uninstall/ re-install ok for 6 weeks .
I would apprieate any help or advice thanks

Hi @BMATH
Thank you your query.
I understand that after updating to Windows 8.1 about every 6 weeks you loose wireless connectivity for no reason and the web pages are very slow to open. If you uninstall and reinstall Windows 8.1 it works fine again for about the same amount of time. You have done this about 4 times with the same result each time.
Do you know if there is any changes at that time , perhaps an update?
You stated you do not believe you have any viruses. Just to be sure here are two links that will help confirm that.

After updating to Windows 8.1 have you checked for Windows updates?
Have you ran HP Support Assistant ?
