MacBook :: Turned On - Computers Lost WiFi Network Connection

Apr 12, 2010

For the past few months I've been using my mid-2007 MacBook (running Snow Leopard) with a Samsung external TV/monitor (with the MacBook's lid closed). I had no problems whatsoever in terms of internet connection to my D-Link DIR-655 router. Yesterday for the first time since creating this setup, I took the MacBook with me somewhere. When I returned the MacBook to my network (closed lid, plugged my monitor back in), I started having WiFi trouble. The WiFi was initially running very slowly and then not at all. The WiFi icon on the menu bar was showing regular strength, however.

The complicating factor here is that when my MacBook is on, all other computers on the network show getting WiFi signals but the connection isn't working for them either. When I turned off my MacBook and powered down/up the modem and router, other computers could connect successfully. (But when I turned my MacBook on, the computers lost connectivity to the internet. I've already played with the router's channels without success. I also made sure there weren't any unnecessary items in my Mac's DNS listing.

MacBook Pro :: Repeated WiFi Timeouts With Home Network Connection

Apr 18, 2012

All day, I am able to use the internet (via WiFi connection) at the library. But when I get home, I can't connect to my home WiFi connection. This was never an issue before. I have done all of the obvious things (resetting my router, clearing saved connections from my computer and joining a 'new' network, check and installed all updates, etc etc), but nothing seems to work. All the other devices in our house are connected to the WiFi just fine.

I run the diagnostic and I'm only green on WiFi and WiFi settings, with network settings and ISP fluctuating between yellow and red, and internet and server is always red. I have tried DHCP Lease renewel (which usually does the trick when I am getting an invalid IP address (169.xxx.x.x) until I get a valid one (192.xxx.x.x). But now sometimes I'm not even getting an IP at all!All I wanna do is unwind, check/reply to emails just surf the web to decompress after my long days.

The internal modem in my PowerBook Pro (mid 2010) shows up as "not connected" in the Network pane of system preferences, but I can't figure out how to get it to connect. When I enter my phone number and click the connect button, I get an error message: "Network Connection The communication device selected for your connection does not exist. Verify your settings and try reconnecting." Say what? It says it exists in the System Preferences, shows it in the list on the left. How can it not exist?

MacBook :: Won't Work With Wifi Network / Drops Wifi

Jan 10, 2011

MacBook. 2Ghz Intel Core Duo. OS Snow Leopard 10.6.6. I'm running a 2006 MacBook with Snow Leopard. A few months back it started dropping wifi connection. Airport would show no connection but would list my network along with others in my building. If I tried to connect with my WPA password it would just time out. At this time I was running Leopard.

Since then I've done a few things.Tried running the Netgear router with no encryption at all (same thing happens). Will lose connection and then time out trying to connect
I've tried the MacBook in a coffee shop with wifi access and at my parents (same NetGear router) and at my new apartment with a horrible Orange Livebox.
Taken the MacBook in to see the genius bar at Glasgow Apple store. Worked fine for them, but I explained it was intermittent but we could not force it to fail. I'm sure if it ran for an hour it would.
At present if I have the MacBook in the living room (where the Livebox router is situated) its fine and wont drop connection. If I walk some 5m to my bedroom it will work for approximately half and hour and then lose it. A few days ago I bought the Snow Leopard upgrade and installed it last night. MacBook runs a hell of a lot faster (yay!) but moving it away from the router and its dead as disco in half an hour.

So to clarify, the MacBook has been tested on 4 wifi networks/ locus with same issue. iPhone, Xbox 360 and PS3 all have no issues with dropping connection no matter where they are in the apartment.

Apartment is a new build and its walls are not made out of lead or kryptonite. Is this a hardware issue rather than software? When updating to Snow Leopard it was an update to the existing OS of Leopard not a clean install.

AIRPORT says the following in System Profiler.

Software Versions:
Menu Extra:6.2.1 (621.1)
configd plug-in:6.2.3 (623.2)
System Profiler:6.0 (600.9)
Network Preference:6.2.1 (621.1)
AirPort Utility:5.5.2 (552.11)

MacBook :: Unable To Share Network Connection / Connected Via Ad-hoc Network?

Dec 31, 2010

I have Alltel Mobile Broadband. Up until the other day, it's been working fine. I'd set up a network on my macbook after connecting to the Alltel network, then I'd enable internet sharing. Then my iPod Touch, iPad, etc would all be able to go online.

The past couple days, however, the connection just won't share.Anyone have any idea what could be doing this and how to fix it?

Hardware :: Switch Time Capsule To Wired Connection / Using Wifi Connection On Smartphone?

Feb 10, 2009

I have a Time Capsule wirelessly connected to my iMac. Since I've encountered some problems with backups because of intermittent wifi connection failures, I want to switch to a wired connection with an ethernet cable. I know I could fiddle with the wifi channels etc. but since the TC is just sitting next to my iMac anyway, I could profit from the higher bandwidth of a wired connection as well.Two questions:

1. What exactly do I have to do to make the switch? Are there any new settings I have to apply? Create a new network?

2. Will I still be able to use the wifi connection to get on the internet using my smartphone?

Software :: Lost Password - OS X Cds Universal To Mac Computers?

Sep 15, 2010

I have a macbook pro that I just got recently so I'm still kind of new to it all, now unfortunately my brother thought it would be funny to change the password but now he can't remember what he changed it to >:/. So I can still use my computer but there are certain things that I'm not able to do without a password. I had read that I could reboot the whole system to its factory settings which I'm okay with because I saved all my stuff to an external hard drive. Now the problem is that I no longer have the os x cd that came along with it but my friend who owns an imac has his, so I was wondering if I could use that one. That is, are all mac os x cds universal to mac computers? I had also read about manually rebooting the system but there were too many people who claimed it had damaged their computers instead so I want to avoid that. What should I don now?

OS X V10.7 Lion :: Force System To Use Second Connection Of Network Connection List For Internet Access?

Jul 5, 2012

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?

OS X :: Internet Connection Flickers When Xbox 360 Turned Off

Apr 11, 2010

I present to you today a baffling conundrum which has been vexing me for months. Around Christmas my sister got a huge raise and bonus, which resulted in a flurry of new technology rushing into the household. All at the same time we set up a new wireless router, (for our wireless modem) an Xbox 360 and SnowLeopard for my MacBook Pro.

I noticed that late at night, after the Xbox had been turned off, my internet connection started getting strange. without the system acknowledging anything had happened (all 5 bars in the airport symbol, my AIM client still claimed i was connected) i would suddenly be unable to load anything (in any browser) or send or receive any IMs.

I would turn my airport off and immediately on again, then the problem would be solved. then, exactly five minutes later, it would happen again. I've been able to connect this "funky-internet phenomenon" as I like to call it, to the Xbox being OFF. I am a walking detector for when the machine gets powered down. this only happens when Xbox is off, and the second it is turned back on, my internet stops doing this.
