2011 17" Macbook Pro constantly drops Wifi connection on Windows 7 but not OSX. What's going on???

On OSX, the Wifi works perfectly. I rarely if ever get disconnected from the internet. However, when I switch over to Windows 7, the internet drops constantly (every 30 seconds or so).
I recently updated my OSX to the newest one (I think Yosemite) that released in December, which wiped out my Windows 7 operating system. Thus, I reinstalled windows 7 on my computer and everything works just like it used to except for the internet dropping 24/7. The weird thing about it is that whenever I "diagnose" the internet connection when it drops, the internet seems to come back to life again (for the short 30 seconds that it's up). I'm not sure why it's doing this. The internet didn't drop constantly on my previous Windows 7 until I reinstalled it.
The internet works fine with a different internet connection on Windows 7, which makes me think that the problem has to do with my internet or router... Has anyone had this problem? Restarting the router didn't do anything.

Do yu have any other Macs running Yosemite on your WiFi Network?

Help needed to troubleshoot why my MacBook Pro repeatedly drops wifi connection

We run Mac & PC laptops, iPhone, iPad on occasion, with ATT DSL, 2Wire 2701HG-B Router. First 6 months of enjoying my Mac, no trouble. Then things started to go south. Been dealing with this problem of dropped internet connection for over a year. Got a new router--the 2Wire 2701, finally got a new phone line put in from the outside to inside. It now seems like the MacBook Pro drops the signal far more than the PC. It seems worse when I'm at my desk, which is only a room away from the router. It can drop the signal about every 3rd or 4th click on the internet. The Networks Diagnostics will show red buttons on the Server and Internet. Been testing other areas of the house, and find it seems better in these other areas, dropping far less. Hard to tell, because the problem comes and goes, like the sun. iPhone has dropped connection on occasion. iPad has occasional slow download of YouTube. Neither of those are troubling.
I tried checking with the Airport Utility, but it tells me it can't find any Airport. I obviously understand very, very little of this. Any help would be appreciated.

Which os are you using?
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

AE ppoe mode in AE only allows macbook pro and iMac to connect to internet but not ipad

I just upgraded to 20MB DSL line and got a new Qwest Q1000 modem connected to an A Extreme.
Since Qwest now has PPPoE, I set the Q1000 modem to bridge mode and turned off Wifi.
Then I Set the AEx router to ppoe mode, entered my username and password from Qwest and all is well with all lights green.
But... only my imac and macbook pro connect to the internet. My ipad, my wife's macbook and an ipod touch cannot connect.
According the Airport Utility, all these devices are detected by the wifi network and they have their own unique IPs provided by the AEx router (in pppoe mode) 10.0.1.7, 10.0.1.9 and so forth, no ip conflicts detected, all the lights green with full access to the internet. Again, only my iMac and my macbook pro actually connect to the internet at full speed.
Does any one know why some devices connect to the internet while others are not able to...
Again, no errors detected anywhere, all modem and router lights green.
Any help is welcomed.
Janickk

Thanks for the reply. Your suggestion did not work. Apparently there is an issue with DNS addresses.
The Airport Extreme in pppoe mode sets the router and DNS addresses to be the same 10.0.1.1. Some devices (like my macbook pro and iMac) ignore this DNS value or use a different (unknown) and then they connect to the internet perfectly. But the devices (ipads and ipods) aquire and set both values (Router and DNS) to be the same, (10.0.1.1 and 10,0.1.1) wont connect to the internet until I manually changed the DNS address in the DNS field.
Question: are these two values supposed to be the same/different/ in both fields in the AExt in pppoe mode?
Thanks

My Macbook Pro i7 lost wifi connection

Hi, my Macbook Pro i7 lost wifi connection. I don't know why, but my connection is lost every time. I've other PC, tablets etc. (Windows, iPhone, iPad) and all is ok. Only Macbook Pro i7 have this problem. Some help?

Well if then, if it is two weeks old, I suggest a trip to the Genius Bar at your Apple Store... it may well be a warranty issue.
I am sorry I was not able to be any help at all besides WANTING to!
Were you running your other wireless machines at the SAME time? And you had nobody in the house using mixers (for drinks or cake and cookie batter) or hair dryers? Clothes dryers....?
While thinking of Brasil and weather- I saw on our public TV station a few months ago- a story about a fishing boat, I think south of Rio de Janeiro, who encountered a hurricane- and only one fellow lived. Ouch!
Report back if you can save the link to the page, or the emails of the answers, to tell what the Apple store said...

Shows wifi connection in settings but not on main page when i switch, shows wifi connection in settings but not on main page when i switch

why does my touch show wifi connection in settings but not when i switch to main page ?

In Setting>wifi, is the a check mark by the network you think you are connected to?
What do you mean by the main page? The upper left of the iPod's screen?

I have Snow Leopard 10.6.8 on my MacBook. Constantly dropping internet connection or message "error connecting to the network" comes up. No wireless connectivity issues with windows 7 laptop or iphone.

I have a MacBook with Snow Leopard 10.6.8. The last few weeks it has been constantly dropping internet connection, and one of these messages appear on the page: "Safari cannot open this page because the server where this page is located isn't responding" or "Safari cannot open this page because you are not connected to the internet" comes up. I will check Wifi and I am connected. No wifi connectivity issues with iphone or windows 7 laptop, this doesn't happen with either of those devices. I have unplugged and reset router, cleared cache, still happening. Any ideas? Thanks in advance.

IPad 2 constantly drops WiFi connection when tethered to iPhone via Hotspot

I have a wifi only iPad 2 that I tether to my iPhone 4 via the personal hotspot. The iPhone and the iPad are constantly being separated throughout the day and my problem is that when the iPad gets back in range of the iPhone hotspot it won't reconnect at all! In fact the iPad no longer sees the iPhone as a wifi option in the network list even though the iPhone hotspot is running just fine (other devices cam still see and connect to the iPhone hotspot)
I have to turn off the iPhone hotspot, wait 2 seconds and then turn it back on. Then the iPad sees the hotspot again and connects.
Also if I turn the auto lock off on the iPad so that it never locks, then it will reconnect to the iPhone hotspot just fine. But the problem with turning auto lock off is that the screen has to stay on all day!
There is obviously something wrong that is happening when the iPad locks. It drops the wifi connection and then does not reconnect when I turn the screen back on.
Is there anything I can do to make sure the iPad reconnects to the hotspot whenever I get back in range without having to keep it on all the time?

I found this post on another thread and tried it for tethering my iPad 2 to my iPhone 4 and so far it's worked great. Good luck!!

Re: iphone 4s - HOTSPOT - WILL NOT STAY CONNECTED
Mar 13, 2012 1:20 PM (in response to coalxman)
I have been having that problem for 6 months and my IT guy finally found a solution by mining the web. I don't know the source of the answer to give credit but it works !
Text of blog posting below:
t does, thanks! I was getting really frustrated with connecting my iPad to my 4S via Personal Hotspot. After a fresh boot of the phone it would work as expected but if the connection was terminated (say by switching hotspot off and on) or after the two hadn't been connected for a while it got into this state where I could see and connect to the hotspot but it would drop a few seconds later then try again over and over.
After a lot of experimenting I finally figured out that there seems to be a pretty serious bug in the hotspot's DHCP server. AP discovery and WPA authentication work great but in this weird state the iPhone will not give the connecting device an IP. The only solution to fix the DHCP server is to reboot the phone.
That being the case, grasshoppertrekker's advice is bang on - you need to give the connecting device a static IP address. This gets around the DHCP issue.
For the less technically inclined, here's how to do that with an iPad:
- Reboot your phone and connect to the hotspot as usual and ensure the connection works
- On the iPad go to Settings - WiFi and tap the arrow to the right of your iPhone's name
- Write down all the values you see under the DHCP tab
- Tap the Static tab (or Manual)
- Enter in the same values you just write down
- Hit "WiFi Networks" at the top to go back
The iPad will now reconnect using the same settings as DHCP would have given it, but without relying on the broken DHCP server.
Optional extra: Instead of using whatever DNS values the DHCP server (and by extension your mobile data ISP) gives you, use OpenDNS IP's instead. This will speed up YouTube due to their partnership with Google and prevent your ISP from traking your web usage via DNS interception. To do this enter the following into the DNS field under the Static tab: 208.67.222.222,208.67.220.220 (note the comma)

On the same iMac wifi can be connected in Win7 but not OSX Maverick

Hi All,
I'm encountering a problem of connecting to wifi on my new iMac. I'm wondering whether anyone in the community has also encountered the same problem.
My iMac is a late 2013 model with 21.7" display bought just 2 weeks again. The OSX installed is Maverick with the latest update. I have also installed Win7 using Bootcamp.
At the beginning, the wifi connection was OK both in OSX and Win7. However, just around 1 week ago, the network connection began to fail in OSX. When logging into the Win7, I can still connect to my router through the wifi and everything is OK. This at least can proves that the wireless adapter in the iMac itself doesn't malfunction and the router works fine. Also all the other devices in my home connects to the same router through wifi has no problem including 2 iPhone5, 1 iPhone4S, 1 iPhone4 and a MBA 2012 model.
However, whenever I switched to the OSX any try to connect to the wifi ends in a failure. The SSID of the network is displayed in the visible network list still but not connectable. By clicking the name and after a while for the iMac to try to connect, a message saying "network cannot be joined" will pop up. Even by running the network diagnosis and specifying a static ip address for the iMac won't help. And I have also tried out some tricks in the community but all seemed not work.
Really appreciate if someone can suggest and help.

Why wont my macbook pro send emails. I can receive but not send

why wont my macbook pro send emails. I can recieve them not send

Go to your email provider's setup page and check what the settings for the SMTP server are supposed to be. Most good providers will even have instructions on how to set up Mac Mail.

MacBook Pro keeps dropping WiFi default gateway on Windows 7 Pro

I have to use Windows 7 for most of the work I do on my macbook Pro. I have the 3.2 bootcamp drivers installed, and I'm running Windows 7 Pro 64-bit. The wireless network frequently drops/hangs. Typically it loses the default gateway, and right clicking and doing a repair fixes it. However, I have to do this 6-10 times a day, and it's very annoying.
I contacted Apple support and they say it's a Windows issues, but none of my other non-mac Windows laptops are having this issue and they are connecting to the same wireless access point.
Does anyone have any suggestions since Apple's tech support can't help with this one? I think it has to be tied to drivers for the Wireless device.
Thanks!

I am starting to ask myself why the **** I spent 1000 euros for a machine that is not able to connect to 95% of all the wireless networks I am using. And the best thing is that os x has these wifi related problems for years, so what the **** are the software guys doing the whole day, it cant be that hard to fix something that essential! And if I call them the tell me that its not an osx problem, the routers (which work with android Iphone windows linux ... ) are the problem. I am feeling fooled and start to get angry!!! Somebody with connections to some newspaper news-tv or whats so ever should bring this information out to people that think about getting such a crappy non-working piece of shxx. Maybe then they will stop ignoring this problem - its really ridiculous!!!!!!!!!!!

Macbook pro retina display wifi connection problem.

Macbook pro Retina display - 3 weeks old - connects erratically to home wifi over Airport Express
iphone and iMac connects to the same wifi network. I am connecting through iphone hot spot to write this question. please help.

I have posted my solution i.e. update airport utility software. Ocourse you needa working internet connection for that!
I have a 27 inch imac, mac book pro, mac book pro with retina display, iphone 4, iphone 4s, 2 x iphone 5. Each device was showing erratic internet connections at some point in time or the other.
I just updated Airport Utility Software. You can find it in Applications/Utilities. When you click on Airport utilities, it opens a window with 2 icons. The bottom icon will look like your airport express. click on that and then you will get info on the right. If , I repeat if, your Airport utility software requires updation, you will be prompted in the info box. Click that and then you will be fine.
However, the irony is that you need an internet connection for this. I set up a hot spot on my phone and did it.

MacBook Pro randomly drops Ethernet connection.

I use my new MacBook Pro both connected wirelessly and via Ethernet to my home network. My network is connected to ADSL via a firewall/gateway router. I have a Powerbook G4 and a WinXP machine running on this same network (wirelessly and wired) without any issues.
For some reason my new MacBook Pro, however, will randomly drop off the network and will often require a reboot to reacquire a DHCP address. At first, I noticed this when transferring large amounts of data to the laptop across the network (retiring my XP machine). I thought I may have a bad cable or bad port on my hub so I switched both. After a couple more transfers, however, the problem seems to have returned.
Mid transfer, the MBP will lose connectivity to the DHCP server and assign itself a 169 address. I am unable to reacquire a 192 address from DHCP and have to restart the MBP to get back on the network.
Needless to say, this is very annoying and not at all what I expected with my new MBP.
Any thoughts appreciated as I am at whits end on this one.

I am having a similar issue. I have not yet tested with standard Ethernet, only Wireless using WPA2.
I have 3 Macs (iBook G4, PowerMac G5, and MBP (Core 2 Duo) all connecting a private wireless network consisting of a Airport Extreme and an Airport Express using WDS. All computers and basestations are running the latest versions of their respective software (10.4.8, V5.7, V6.3)
ONLY the MBP has the following problems: dropping the connection, failing to reconnect after sleep, and failing to obtain an IP address via DHCP after connecting.
The signal power reported by both the menu-bar widget and the Internet Connect application varries continually on the MBP, even though it is sitting 2 feet from the Airport Extreme basestation. Sometimes full strength, sometimes only two bars.
I have removed all preferred networks from the Network system preferences and re-added only my network. I have also removed the passwords for the routers from my keychain.
The MBP will often-times simply drop it's connection. When it does that, it will not automatically reconnect to my network. If I put the MBP to sleep it often-times will not reconnect when it awakes either. Sometimes it does, but I cannot decern a pattern. If it does automatically reconnect it will usually not obtain an IP address from the basestation.
Simply toggeling the MBP's Airport off and then on will almost always get it to find my network and automatically connect. Even if it does connect to the network, it doesn't always obtain an IP address via DHCP. Again, if I simply toggel the MBP's Airport off and on then it will usually connect and obtain an real IP address.
All of these things happen within two feet of the basestation, as well as more than 20 feet away. Both other Macs continue working just fine even while the MBP is having problems.
This is not an issue with the basestations or my configuration. It must be a problem with the drivers for the Airport card in the MBP.

I can send photos TO my MacBook Pro from my iPhone 5S using AirDrop but not vice versa.

I am using OS X Yosemite 10.10 on my MacBook Pro, which has AirDrop enabled and is available in Finder and I am using iOS 8.1 on my iPhone 5S. I can send photos to my MacBook Pro using AirDrop from my iPhone but I cannot send photos to my iPhone from my MacBook Pro using AirDrop. I have to email the photos to myself via email. Is there anyone else having a problem with this or does anyone have any advice on how to fix this problem? When dragging a photo to my listed iPhone in AirDrop on my MacBook Pro I simply get an error notification, which is very frustrating. Thank you for your time.

Sorry, please disregard this. My roommate rebooted the router while I had stepped outside and now it's all running again.
At least this will be a possible option for anyone else that has this problem

My MacBook Pro force shut down three times in a row. What is going on?

I just updated my MacBook Pro from the app store and now my MacBook force shut down three times in a row.
I need to know what is going on. I am a college student and can't afford to waste time to figure this out. If it happens again I am just going to take it to a repair store to find out what is wrong. If it ends up that it can't be fixed then I will have to buy a new one on the spot.
I hope I don't have to buy a new MacBook Pro.

Reboot in safe mode and test again,
