Airport internet connection problems in OS X but not in XP or iBook

I have an iBook and an iMac, and the iMac has Leopard and XP on it. When in Leopard, most of the time, the internet connection is extremely slow and can never load a full page in Safari, always quitting halfway or the connection drops completely.
When I go into XP, the internet connection is perfectly fine and there are no speed issues and the connection is never dropped.
When I use my iBook, there is also no connection problems.
The crappy internet connection also affects Mail in such a way that I cannot quit Mail or Shut Down (until I force quit Mail).
I called apple the last time this happened and their solution fixed it, but the problem is back again.
Does anyone know how to fix this, or does anyone know if there is something wrong with my Airport?
(Its an aluminum iMac, 2.4 GHz running 10.5.7, and not using the Beta Safari)

Hello, I don't think I can help, I do have 10.7.3 & W7 Ultimate, but I run W7 in Parallels...

Internet connectivity works in OS X, but not in Windows 7 Ultimate

I have a new Mac Mini. Mid 2011. 2.3 GHz i5. 8 GB RAM.OS X Lion 10.7.3. Windows 7 Ultimate.
I used Bootcamp to install Windows 7 Ultimate on a partition. All drivers are apparently up-to-date -- they were installed through the Bootcamp Assistant. Internet connectivity works fine in OSX, but is very unstable, if even existant, in Windows. If I do have a connection, I have download speeds of <1Mbps.
Any thoughts on what may be causing this?

Internet connection problem- IP address from router, but will not connect

My Powerbook will connect to an open wireless network where I am and is assigned an appropriate IP address, but neither Mail nor Safari will connect properly. I know the system is working, because other people with wireless laptops can connect fine. I tried quitting everything and rebooting a number of times but no joy. I can't see anything in the settings that I can play with that will make a difference, but I can't understand why it won't connect.Very frustrating. Network diagnostics can't help either. I don't have access to the modem/router to reset it...

I'm having the same problem. I'm traveling and I was able to connect to the wireless network on my G4 Powerbook at the hotel this morning. Now I'm in a different location and I have a strong open wifi signal, but no internet connection. I can add that I also brought my iBook and it works fine on this network. Both worked just fine on this network back in October. I've tried in no particular order: rebooting (4x), Network Diagnostics in Safari ("N.D. cannot fix the current networking problems...make sure you are using the correct network settings"), creating a new user, comparing Network settings between the two Macs (the only difference is the last 3 digits of the IP assigned using DHCP), deleting preferences (airport, internetconnect, & networkConfig.plists, NetworkInterfaces & SystemConfiguration.plists), turning Airport off then back on, and setting up the iBook to share its internet connection. Internet Connect says that I'm connected to the network and have a full signal. Any other ideas?

Just one month before i bought iphone 5... but the iphone has the internet connectivity problem... while a iphone 4s is cathcing 3G tower, whereas iphone 5 is catching 2G network only.... I've tried so many things to get recovered, but alas, nothing is workable- such as- restaring the iphone, reseting the networks etc... Please help me out from this problem..

to be clear, my phone works fine when not in motion in a vehicle. If I pull over and come to a complete stop, remaining in the car, my phone works.
And while the phone is not working when I'm in motion, an internet search or a text message will go through, but I can not use Siri or any voice assistance when doing the text message or internet search. The microphone is greyed out.
So this is a unique issue, which appears to be the iPhone and not Verizon.

Airport Internet Sharing Problem Mini - PC Laptop

Airport Internet Sharing Problem
My setup is:
Cable Modem -> Mac Mini --> PC Laptop
... with the connection between the mac mini and the PC laptop being the built-in mac mini airport using internet sharing.
Hi, I've been trying to set up Airport internet sharing with the mini, to no avail. It works off & on, but invariably the internet connections drop after about 10 minutes. The only way to get it started again, is to go into internet sharing, turn off internet sharing, then turn it on again. It will work for another 10 minutes or so (slow) after gong back to the PC laptop and reconnecting, then it chokes again.
I've tried the connection both with & without WEP, same behavior. I read somewhere that OS X only plays well with using Channel 1, so I tried that. No luck. Tried with and without Interference Robustness, no luck.
Tried with WEP on and using 40 bit hex keys using a "$" prepend in the mac as suggested on this web page:
http://www.macosxhints.com/article.php?story=20030803030354585
Same behavior, works for 10 minutes, then it chokes again.
Tried with & without the firewall.
Yes, personal web sharing is on.
The PC laptop works fine with any number of other wireless routers out & about town, at my girlfriend's house, so forth.
Any chance I have a bum mac mini wireless card or antennae or something? The reception strength on the PC laptop is good.
Just don't know what to make of it. So stupid, it seems like something pretty basic that ought to work.
Yeah yeah tell me to get a wireless router, but I'm not going to do that, that's one major reason I bought the mini in the first place and it would be nice if it worked as advertised.
Any other suggestions?

Works better now...
this is me again. A week ago or so, I noticed there was an automatic update to the wireless on the mac mini.
Since then the performance is much improved. My PC laptop connection to the mac mini no longer drops spontaneously.
Much improved! Thank you very much!
Yes, on occasion, when I leave and then come back to use the wireless, the laptop will not reconnect after multiple attempts; I have to turn of internet sharing and flick it back on again, but then it works all evening fore hours and hours straight with no problems.
Thanks Apple! It's usable now!

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.
Bought my girlfriend the newest Macbook Pro 13" and began experiencing problems with my wifi the moment we got home. Her Macbook would not connect to our home Wi-Fi while my old Macbook Late 2008 running Snow Leopard connected without a problem. Airport would say that it had a Self-Assigned IP address (168.x.x.x). Did not realize it was a Lion problem until after using her Macbook Pro and becoming jealous of the new OSX, I upgraded. Soon after I was unable to go online. Luckily I had my iPad 2 and I began to scoure the net for help. Ran into allot of suggestions but it was not until I tried the following all together was I able to share the good new, from my Macbook. Hope this works:
First go to Preferences > Network and click on the cog next to the + and - on the sidebar and click Set Service Order
     - Move Wi-Fi to the top and click ok.
     - Set location to Automatic
     - Click Apply
     - Click Advanced
     - Click the "-" on the selected Wi-Fi router you wish to connect to
     - Click Apply
     - Click Lock to Prevent Further Changes
Go to your Mac's harddrive, (Macintosh)
     - Go to Library > Preferences > SystemConfiguration >
     - Delete "com.apple.airport.preferences.plist" file
Turn off your computer
     - push and hold Option+Command+R+P
     - turn on computer
     - when the grey screen turns on you will hear the OS X "ON" sound (for lack of a proper term) and it will momentarily restart.
     - you will once again hear the "ON" sound, let go of all keys.
     - this resets your PRAM
Go to Preferences > Network > Advanced > + sign
     - click Choose a Network
     - Select your network and enter password
Viola!!! I tried this on my Macbook Late 2008 and my girlfriends new Macbook Pro 2010

     No you are clearly mistaken. The Self-Assigned IP address problem exists on many Macbook Pro models, including the current model, which I mentioned as being the original computer with the problem. While my 2008 Macbook is older it was working perfectly on Snow Leopard and didn't suffer issues until switching to Lion. So clearly the problem exists on the operating system and not so much the hardware.
     I called Apple Support and they had no fix for the problem and told me that this would hopefully be addressed in a subsequent update. It wasn't until I came accross the answer after trying many different methods that I got both of the Macbooks to connect to my router. Otherwise I wouldn't or could not have been surfing the internet for the last 4 months.
Cheers.

Omni 10 mostly internet connection problem, also difficulties responding generally

Dear all,
For two weeks now i am proud owner of an omni 10 tablet. However, i already encountered some problems like the loss of the audio System, which was luckily restored with the help of the hp support via telephone.
Unfortunately, my tablet is not properly connecting to the internet since yesterday. It also has problems opening PDF files with 'adobe read', deleting or newly creating appointments in the challenger app and foremost it sometimes does not open the settings section depite repeatedly tapping on its button..
Most important currently is the internet connection problem. Is connects but says at the same time that the connection is limited. Additionally, it does not offer any solutions to this. That happend with three differend routers so far..
I hope you can help me
Greetings

What do you mean it did not work! What were the results of the diagnostic tests?
Have you contacted your ISP to determine if the problem is on their end?
Have you changed your router channel? Sometimes this resolves wireless problems.

Internet connectivity problems. Conflicting IP address?

For the last few months I have been experiencing significant internet connection problems on my mac mini. Although at times my connection is ok, the majority of the time I'm suffering from what would best be described as an "intermittent" internet connection. It seems that my internet connection is constantly cutting out for short periods of time before re-establishing itself.
I'm connected to the internet via a wireless network (netgear router). There are also two windows machines (one laptop and one desktop) and a PS3 connected on the same network (also occasionally there is a macbook connected to the network too).
I've been with the same ISP for over a year now and previously had always experienced a good connection, also all the other devices connected on this network seem to have fine connectivity so I doubt there is any problem with my service provider.
It could be a coincidence but the emergence of the problem seems to have conincided with my flatmates purchase of a laptop. When my flatmate first connected his laptop to the internet I received a message on my mac mini stating there was an IP address conflict, although I have not had that message again and I seem to suffer from bad connectivity at all times, not just when my flatmates laptop is turned on! Could these to issues be related?
I'd be very grateful for any advice on how to resolve this issue as it's getting to be a very significant problem, thanks in advance for any replies...

Also try using the open dns servers instead or your ISP's. System Preferences>Network. Advanced>DNS. Click on + and add the following: 208.67.222.222 and 208.67.220.220. Hit Ok,then Apply.

Persistent internet connection problems.

Every 8 months I get a spate of internet connection problems that last for a few months. (Meaning I get relief for two months at a time, and bad service for two months). When the previous bout of internet connection issues happened I was fortunate enough to get a good technician who showed me how to reset the connection at the fios box at the entrance to my home, by unplugging the backup battery, unplugging the connection box and then reconnecting the battery and plugging back in the connection box. The technician had remarked that there were problems with the main fios connection system to the townhouses, and somehow that got fixed.
This time I have not had as much luck. The technicians on duty have had me reset the cable router (which isn't the problem) and even replace the cable router (also not the problem). Fortunately I have remembered the previous technician's solution and am doing that every three days, without contacting technical support since they have proven useless at this time, only continuing to have me get new routers that do not even connect without the previous steps.
How do I get Verizion to bother to listen to me? At this time I am really wishing Cox was in my neighborhood, since I was able to go at least eight months straight without problems from them.
I am hoping that this causes someone to check on this problem. You had a good technician on technical support once, but not now.
By the way - this has been going on for over two years.

Since we haven't heard back from you or have received a form submission as requested in your private support case, it appears assistance is no longer required. If you need any future help with your Verizon service, please make a post here on the forums so we can assist.

RG54G2 Wireless Router Internet Connection Problem

Hi,
(apologies for the long message - trying to cover all details - summary: wireless router often drops internet connection)
I recently bought an RG54G2 Wireless Router, a CB54G2 PCMCIA Wireless card and a D-Link GWL-630 PCMCIA Wireless card. In addition to two laptops connected to the wireless router WLAN, I have two PCs (one Win WP Pro SP 1 and one Win98SE) connected to the router via wired LAN. I also have a SurfBoard SB3100 Cable Modem connected to the WAN port (this connects to my ISP - Optusnet (Australia) via DHCP).
The problem I have is that the internet connection is disconnected many times a day (often every few minutes, sometimes an hour or so). I am able to reconnect by resetting the wireless router via the wireless router configuration page. When the internet is disconnected I am still able to access the computers on the LAN/WLAN (via Windows Explorer and Ping), I am also able to ping the router and the Cable Modem, but nothing outside of the cable modem.
Also, when the internet is disconnected the System Status page indicates that the router is still connected to the internet, and the Diagnostics page passes the Test Connection test, though no external pings work.
I did not have this problem when the cable modem was connected directly to the Win98SE PC (and other PCs via ICS).
I have disabled the WLAN and the problem still exists with only the wired LAN.
I have changed numerous settings in the wireless router config page with no success (eg disabling DHCP and setting each IP address, minimising LAN and WLAN speeds to 10 and 11MBps plus others).
I have upgraded the wireless router firmware to R1.0.6.0 (no change to the problem).
Searching on Google I have found several other cases of routers with unstable internet connections (none refering to the MSI routers), but none had solutions that helped my situation (most replies suggested updating the firmware).
Any suggestions of how to make the router internet connection stable?
Thanks,
Mike

maybe this is the FIX 4 wireles router internet connection problem
please let me know if any one fix the problem with this tips
thankz

Subject: SOLUTION to my router loosing connection to Windows XP
Reply | Reply to Author | Forward | Print | Individual Message | Show original | Report Abuse
I am happy to report that after 8 days of constant battles, reboots, phone
calls, cable pulling, router changing, it seems that I finally have found a
combination that has had me using Verizon DSL account for over 12 hours so
far without any kind of interruptions.
Since so many of you tried giving me comments and suggestions, I felt that
it is necessary for me to post this here so that the next person will not
(hopefully) need to go through this hell as I did!
My original problem was that when after I purchased a D-Link Wireless Router
DI-624, I would get disconnected from Verizon DSL at least once every 2
hours or so. My internet access would "freeze" and then a little popup box
at the bottom right system tray would tell me that the "LAN cable has been
unplugged". After about a minute or so, my internet connection would be
back working This was NEVER happening during the 2+ years I was using my
Westell modem alone (running in router mode).
Please keep in mind: The problem I was having was not wireless related as
it was happening to the desktop computer to which the router/westell was
connected to!
During these last 8 days, I tried: one DI-624 wireless router, two Netgear
614v3 routers and two Linksys WRT54G v.2 routers. In addition, I received a
brand new Westell 2200 modem from Verizon. I also tried about four
different CAT-5 cables. Here is the final outcome:
I have the Linksys WRT54G (version 2) wireless router connected to the
Netgear Fast Ethernet FA310TX network card in Auto-Sense mode (using the
built-in XP drivers, as Netgear told me that there was never a newer
revision released). I have DISABLED the built-in 3Com Gigabit LOM (3C940)
network card (via the ASUS P4C800 Deluxe motherboard BIOS), DISABLED the
Zero Wireless Configuration service, and have put in the IP/Gateway/DNS
address numbers inside my Windows XP Network Connections | LAN setup. My
operating system is Windows XP Pro SP1 and the modem is a Westell 2200
configured as bridge only.
If my situation continues to be stable, I *might* try to go back to the 3Com
built-in card (disable any power management) and then re-enabling the Zero
Wireless Configuration services. But in reality, I am happy with the way
things are and have already spent enough time trying to get my router to
work with Verizon DSL without having it drop connections!
Now, the next step will be setting up the WIRELESS part of this. I don't
even yet have a laptop with me on the premises, but the 802.11g card that I
already have is the D-Link DWL-G650. I hope and assume that this will work
okay with the Linksys...
One thing I must say is that I never realized that how many problems other
users are having. I would have thought that since 802.11x has been around
in the mainstream by now 2+ years, that things would have been much more
"system friendlier". And again, my issues were not even WIRELESS related.
All 3 tech supports were not really helpful, as none of them realized that
the problem is somehow between the router and Windows XP (Ethernet card?)
loosing a connection, which of course results in Verizon DSL loosing the
connection also.
One other comment about the Netgear 614 v.3 router: A number of people have
responded to tell me that they have had this random "router resetting"
happen to them (where the routers behaves as if someone turned the power off
and then back on, and the lights flash) just as if you first turn it on). I
was lucky to witness it myself during one of the "disconnects" that I had.
This was actually the reason why I went back to try the Linksys one more
time. So, I would definitely recommend staying way from this 614 (version
3) model.
Once again - THANK YOU everyone!
