IMAC Wireless Internet Connection Problems All Of A Sudden

My Imac is well over a year and a bit old and has been able to connect to my wireless internet connection absolutely fine until the past week and a half. At first the connection wouldn't work and when I would turn my airport on and off and reset the router, it would eventually work, now that is not working at all. My airport status is either showing 'airport is turned on but is not connected to a network' or 'airport has a self-assigned ip address and may not be able to connect to the internet'
I have formatted my imac twice and still no avail and the last format I tried to join wirelessly straight from boot but it wouldn't join saying 'there is a problem with the wireless connection and you're not connected to the internet.' the annoying thing is I can see the network sitting there and can't join it, my network is also unsecure so no need to input a password. All my home PC's and my Iphone and Blackberry find the network easily enough, although recently the Iphone has began showing only 1 bar of wifi connection.
I am at my wits end as I am unable to connect at all now, I am all out of ideas and have been bashing my head off a wall for the past day without any connection at all.
My router is a buffalo AirStation wireless G high power model, my IMAC is an intel core 2 duo 20", if you need anymore information of my hardware I will gladly provide it. I'm running MAC OSX Leopard 10.5, out the box as I've been unable to run any software updates as I can't connect to the internet.
Please, if anyone can shed any light at all on this issue I would definately try anything.
Thanks in advance and regards.

Anytime you see a self-assigned IP address in your network prefs you know it surely is a problem
with your router configuration. Power down all equip ... make sure modem is off for at least 5 minutes
restart modem, restart iMac ... check your network pref on iMac and make sure it's not 169.x.x.x
If so you will need to recapture the settings from your ISP's modem to the Buffalo.
Always use a secure wireless connection (WEP, WPA, WPA2) or else the whole neighborhood will suck down your bandwidth the slow down what your paying for. I use Time Capsules or AEBS (Airport Extreme Base Stations) that allow you to stealth mode and lower signal output and make the device
as a "closed network" ... meaning no one else can see and tap into your WIFI home network!
802.11N is better than G. and especially when you can use dual bands 2.4 / 5GHz to stop various home interferences. The backup of Time Machine only makes life much easier also! Xtech

[SOLVED] Wireless internet connection problem during installation

Hi to everyone!
I ask you a help in activating my wireless connection.
I tried to install from the recent ISO (201208 - via CD)
but I found some problems in activating a wireless connection in the first steps
of the installation guide.
My laptop is a Hp pavilion dv5 1020-el, with an Intel wireless 5100AGN internal interface.
So I did:
1) iwconfig to see my devices and the system detects my wlan0.
2) followed the Wireless_Setup page from wiki to set it
3) used wpa_supplicant and passphrase to set my ESSID name and wpa key.
4) iwconfig then showed wlan0 associated with my ESSID, with Power ON and Encryption OFF.
I could not try a connection via ping command.
Even wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf did not work.
Maybe the problem is with Encryption OFF.
Thanks for your attention!
EDIT:
I solved this way,connecting to an open wireless open network:
1.(from boot) I created a profile in /etc/network.d/ from /etc/network.d/examples
2. started a # netcfg 'my_ESSID'
3. # ping -c 3 www.google.com
All is ok! I can install Arch Linux from my smartphone as a router.
But I couldn't connect to a WPA protected wireless network yet.

Thanks to everyone who responded to my question. The company who provides the wireless internet service to my apartment complex moved the antenna next to my unit and claims he boosted the power. As the saying goes, "The squeaky wheel gets the grease". I complained almost daily to the apartment manager and she, in turn, griped to the provider which eventually led to the "solution" above. Using Skype is still shaky as the person I'm calling isn't always able to make out what I am saying. So, I use Skype only when I REALLY need to make a phone call. Even though none of your suggestions solved my problem, I am still very, very grateful to all of you who tried. Thank you very, very much! -- Matt

Wireless internet connection problems

Hi there,I'm from Holland so if my sentences come off weird, you know why... I got aquestion about wireless connections in the big city. I live in a fairly bigcity and my connection is failing at least 10 times a day... My provider toldme this might be because of the fact that i can receive a ton of signals (otherwireless network). Now, i don't buy that so im looking for a solution. Incomparison, i don't believe people in large cities in the US have theseproblems and some of them harbor more citizens than my entire country does...So i wanted to ask: I have this internet package (check out the specs if you will) is there something else that yourproviders offer and by that, overcome the frequency overload... modem differenttype of modems or something like that...? please help! thnx in advance!

I don't know if this is going to help anyone or not, but I was having a similar issue to many of the users on these discussion boards. My wireless was connecting and then dropping from 5 to 3 bars, then I would lose connection entirely for about a minute, then it would reconnect and work fine for 5 minutes etc. Sometimes, my airport would work great the whole time.
Anyway, I called applecare support and followed their various suggestions, to no avail. The IT guys at work couldn't figure it out either.
Fortunately for me, my computer was purchased through an academic institution, so I have onsite hardware and software support. With this being said, the hardware technician at work determined that the wire connecting my airport was lose. Since the airport is located at the bottom of the macbook near the hinge, the technician suggested that opening an closing the screen would affect how well the airport was connected given the lose wire.
With the lose wire problem taken care of, I don't seem to have these problems anymore. Also, before the problem was fixed I needed to be within about 20 feet of my router to get a good signal, and now I can pretty much go anywhere in my house and it works great.
Something to look into.

I have a MacBook Pro and all of a sudden I cannot get wireless internet connectivity to my router or any other router, I get connectivity through the ethernet port but not wireless. This was working well till this morning

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.

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

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!

New iMac wireless internet crashes repeatedly -- why?

Just set up the following wireless LAN: Netgear WGT624v3 wireless router as access point between a broadband cable modem, a new 27" iMac, a PowerBook G4, and a Canon wireless printer. Everything works great except for one thing: whenever I'm trying to use the internet on the new iMac, my internet connection crashes and I have to manually reset the modem and router. This happens when downloading a file even as small as 2 Mb. As you can imagine, this has become incredibly irritating, as none of us can get anything done on our new computer without me having to come over and flip a switch on the power strip to repeatedly reset the internet connection.
The Netgear router is about as old as the PowerBook (3+ years)--I see it's listed "EOL" (end-of-life) on the Netgear website, and I'm wondering if it may not be powerful enough to handle the new iMac? That's the only thing I can think of, since using the internet with the PowerBook causes no problems at all. I don't understand the subtleties of Airport v. Airport Extreme, 802.11b, g, n or whatever, to figure this out on my own.
Anyone had a similar problem and/or can confirm that the router is the culprit before I needlessly spend money on a new one?

Some things you can try, if you haven't already:
-Make sure you don't have any cordless phone base stations operating near your router.
-Are any other electrical appliances (like microwave ovens or fluorescent bulbs) operating when your wireless connection fails?
-Power down the router and the iMac, then restart each.
-Change the channel your router uses to broadcast its signal. You should be able to do this from the web browser interface most routers support.
-Check Netgear's support website for firmware updates. Some routers can be commanded to check this from the web browser interface.

ITunes 8.1 works great but killed wireless internet connection

I installed version 8.1 on both my laptop( PowerBook g4/ OS 10.4.11) and desktop (imac intel / OS 10.5) and after restarting the computer, the wireless internet connection stopped working on both.
I would open Safari and it would be a blank page and and the circle would keep spinning.
So I tried my laptop at a different wireless hotspot and had the same result.
I then tried repairing permissions and I got a list of problems with iTunes/Network Utilities, they repaired and now when I open Safari I get the message that it can not connect to the internet.
I do get an internet connection using ethernet on both.
Any ideas on how to fix this problem?

Did you by any chance also update the firmware on your Apple Airport Extreme (if that's what you have)?
I thought 8.1 killed my connection to my Apple TV, but it was the faulty firmware (see reports elsewhere in these forums).
Now that I have rolled back from 7.4.1 on my Airport I plan to try iTunes again (with white knuckles).

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

The only thing I can suggest is for you to follow as many steps in this document as you can: Troubleshooting Wireless Network

PLEASE HELP! INTERNET CONNECTION PROBLEMS....

Hey guys!
I just got myself a brand new itouch last week (I'm SO excited), the problem is this, i cannot get it to connect to the internet! I've got a wired connection, and i need to know how to either change everything over to wireless (which would be an expensive pain as I've got a HD tivo, a Wii, an xbox 360, plus my computed that are using up everything on my router) or somehow get a wireless router connected to all of this somehow...my cable modem has only one output, too. So, I feel TOTALLY helpless! Maybe there is something I'm missing or not thinking of or something, but I'm so frustrated! I love my itouch and want to definitely keep it but...how do i get it to connect to the internet? Sorry about the rambling message...Thanks for listening...
~joey~

While an Apple Airport is a very nice router (and is clearly very Mac friendly in terms of setup and such), it is expensive.
You could achieve the same results - a wireless connection for your Touch - with a low-end wireless router from Belkin, Netgear, Linksys, etc. You only need 802.1 g/b (i.e., some of the newer, "faster" access protocol won't work on the Touch anyway), so you could go with some of the lowest-end offerings from these other manufacturers. Generally, such things are available from office supply (e.g., Staples) or big box (e.g., Best Buy) stores for under $50. You could also search somewhere like Craigslist and find and older one (that someone is upgrading from) for for next to free. If nesc, go to the maker's website to download a manual once you have a used piece of equip. Since you seem to be a PC (windows) user, you should be able to run the setup programs on the manuf-supplied CDs for most anything that you find.
In most cases, you can bridge your "new" wireless router to the wired router, thereby keeping your wired router fully in place. Or, you may be able to swap everything over to the wireless router (using its wired ports...most wireless routers have a least 4 wired ports...for those devices you have that aren't wireless). Depending on what you get for a wireless router, you have a variety of options.
Hope this helps.

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.

Slow wireless internet connection using airport extreme

My wireless internet connection works but is very slow (<80kbs). The problem seems to be with the airport extreme (brand new, purchased in May 07) because my connection is very fast (>6mbs) when i connect by wire to the airport extreme base station. Signal strength is strong, so i can't figure out the problem. Any ideas?
imac Mac OS X (10.4)

BK37, I hope you've solved your problem by now. But if not, and for the benefit of others reading this post, let me share what I (finally) discovered when I had virtually the same problem, i.e. 8mbps wired speed, <50kbps wireless speed.
I tried literally <span style="font-style:italic;">every suggestion I could find in the Airport discussions. First, I can assure you that changing the channel can give you incremental speed improvements in some instances, but for radical drops like yours, it's not the answer. Nor is turning off ipv6, or changing to WEP, or turning off Remote Access, or moving the AEBS, or or or or or....
With such a radical drop in speed, it's most likely you have a hardware-related blockage somewhere. In my case it was my wiring configuration. My setup was France Telecom Livebox (ADSL modem / ethernet & 802.11g router) --> Ethernet cable --> Linksys RTP 3100 IP phone adapter / router --> Ethernet cable --> AEBS --> 3 Airport Express set up to extend network and run AirTunes. After eliminating every other possible problem, I narrowed it down to the Linksys router, which for reasons I have yet to figure out was trapping the speed to the AEBS. I ethernet cabled both the Linksys router and the AEBS directly to the Livebox and presto! Back to blazing speed.
Hopefully this info will be helpful to you or some poor soul in the same situation, as I would have loved to have had it myself before I pulled every hair out of my head!

For those who constantly lose their wireless internet connection using WRT54G

Ok I was constantly losing my wireless internet connection on my LAN network when using my laptop, I tried everything to no avail,until today. Heres what I did to solve my problem
1. Upgrade your firmware for the WRT54G to ver.6
2. Reset your wireless router
3. Unplug all cables and wires from your Pc and router
4. Connect your Pc directly to your cable modem and obtain an internet connection
5. Now transfer files you want to keep from your laptop onto a usb flash drive or burn them to a disk
6. Reformat your laptop so that it goes back to all factory settings just like when you bought it
7. When completely done reformatting run software that came with the WRT54G on your desktop pc and follow all instructions,when prompted to type password type the password you last used
8. Go to your laptop and it should pickup a LAN,click connect, it will ask for the encryption key so type it in(whatever you typed when re-installing your wireless router)
Congratulations you are now back up and running,install files saved earlier back on your laptop and enjoy.This is what I did and it solved my problem as a matter of fact i typed this from my laptop and has not dropped my wireless internet connection yet.
NOTE SAVE ANY AND ALL FILES YOU WANT TO KEEP AS REFORMATTING WILL CAUSE YOU TO LOSE DATA!
IAM IN NO WAY RESPONSIBLE FOR ANY ERRORS OR PROBLEMS THIS PROCEDURE COULD CAUSE IF DONE INCORRECTLY!

If you bought a version 5 or 6 return it to where you bought and apply the money towards a WRT54GL v1.x You'll be much happier. You could spend time online rather than pulling your hair out trying to figure out whats wrong. I setup 6 Linux based WRT54G's with no issues before I was given the task of setting up a version 6. Worked for about an hour. Told the guy to return it for a GL. Long story short, set it up in a matter of minutes and he was online. That was 3 weeks ago and he is very happy.

Time Capsule Degrades Wireless Internet Connection: Help?

Time Capsule Degrades Wireless Internet Connection: I am in FL using Brighthouse Cable as my internet provider (15MG down). The internet connection speed is slower than a dial up connection when wirelessly connected to my network to my Time Capsule. When I remove the Time Capsule and replace it with Brighthouses Netgear router the internet speed are normal (fast). Additionally, the internet speed is OK when I first hit a website, but the speed degrades rapidly as I access additional web pages. I no longer use my Time Capsule and therefore are not getting my back-up protection. (NOTE: I tried Verizon Fios and had the same problem.) Can anyone help?

Bought the time capsule in Oct 2013. I have a Sagemcom 2864 modem from Bell but used through Teksavvy. The 5 ghz has been flaky until I upgraded to Yosemite 10.10.1 I think. I had a closer look at it and it appears that the wifi is ok. I was thrown off by the wifi symbol being all animated in the menu bar. I was able to ping the time capsule via wifi. All the status lights on the modem looked ok. Next time it happens, I'll see if I can get some more details. Do you know if there's anyway to get some logs from the airport utility?

I ended up giving up on it for the time being, just using my SMC NIC. Would be quite interested in finding out what the problem is though.
Anyone else in the same boat?
Hi,
Your problem is not the same, SiliconMan is trying to connect with a dial-up modem not LAN. Your problem sounds like it may be configuration, do a search on this post, I'm sure you will find people with onboard LAN troubles. It's hard to troubleshoot though since you didn't provide any info about your computer. Good Luck
