Mac OS 10.9 Mavericks WiFi Issue

Since I have upgraded to Mavericks I have experienced a problem connecting to wireless networks, all wireless networks regardless of security settings. The system displays the exclamation mark and doesn't get an IP address from the router. I have discovered a work around but it is very inconvenient and I would really like to get to the root cause and resolve the problem. Here is what gets my WiFi working;
If I boot into safe mode, ie. hold down the shift key during reboot, WiFi connects normally. After logging in to my laptop account I reboot and again the WiFi connects without issue. If I then have to reboot the system again I will experience the same issue in receiving an IP address from the router. In order to connect again I have to first boot into safe mode, etc.
One other note, if after booting into safe mode I reboot without logging into my account the issue is not resolved the sequence must be;
1) Boot into safe mode
2) Log into account on laptop
3) Reboot normally
Anyone have any ideas why booting into safe mode and then immediately rebooting resolves the issue?

Mac osx 10.9 Mavericks wifi issue

Ok so Wifi is really starting to annoy now....
I have a 2013 Mac Air (about 1 month old). I upgraded to mavericks and now EVERYTIME the machine goes to sleep, i close the lid, whatever the wifi connection is shut down and on logging in again, the wifi doesn't connect. I have to manually turn off wifi and then turn on again before selecting my network (and usually needs 2 attempts).
This is unacceptable.
Does anybody else suffer from this issue? any ideas on how to fix it (other than reverting back to MLion - if that's even possible)
Thanks in advance for any responses
Kind Regards
Supersleb

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Reinstall OS X.

Mac Pro 5,1 Maverick OS Issues

Well here's to my first post! I've kept up quite a bit with the forum but haven't really had a chance to contribute! This is a pretty tricky issue as it seems there's a few of you with a similar issue out there but not really anyone has come up with anything to get it fixed. Maybe we can figure this out..
So I've owned a Mac Pro model 5,1 (MID 2010 model) since about 2012 and have had not many issues really AT ALL with it until I needed to upgrade it to Mavericks. Now I'm super hesitant to update to Yosemite for sure.
I run a lot of professional audio programs such as, Logic Pro, Logic X, Ableton Live, Cubase, Pro Tools, Etc.. As it's main job is music production on a daily basis. Currently, this bad boy runs on 32gb of ram, a 960gb Solid State hard drive for my main drive, and 3 internal 2TB HDs. 2.4Ghz 8-Core Processor Intel Xeon.
When I updated to Mavericks - Logic 9.1.8 tends to be VERY unresponsive at times (even getting the pinwheel for a bit). Right-click menus within the program are slow, the EQ itself is lagging as well as meters.. SUCH a bugger and really annoying! Even Logic X seems to show some instability.
Now here's the kicker.. I have a Macbook Pro laptop with the exact same programming setup and everything runs smoothly on it. Everything! The processor is pretty quick i7 on it, but I don't see why that should have ANYTHING to do with it.
I've upgraded my ram, swapped hard drives, reinstalled Logic and STILL this issue is occurring. I feel like I've tried everything. Anyone care to chime in? Any success stories yet?

Hi ...
A Safe Mode boot deletes some system caches that may help after an OS X upgrade.
Top left corner of your screen click the Apple  > Shut Down.
After your Mac shuts down, wait 10 seconds, then press the power button.
Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator.
Once you are in Safe Mode, go back to the Apple  menu. From the drop down menu click: Restart
About Safe Mode.

Mac OSX 10.9.4 Wifi issue & crash

Hi Communities,
I have been using my mid-2009 Macbook perfectly until I decided to install a new SSD for this mac. After a clean installation, the Mac's wifi had gone crazy, I looked over our forum but whatever method I tried didn't work (turn off Bluetooth, delete files in Configuration, fresh installation, etc)
So, I decided to leave the Airport alone and bought a USB wifi receiver. It works really well and sometime, it could activate the Airport wifi for few minutes (but just few minutes won't be helpful so I keep Airport wifi OFF)
However, the crash always happens whenever I want to upload pictures to my Flickr or watch Youtube videos. Here's the Crash report

It's quite annoying because I can't use the Airport wifi, but I know it's still working for sure; there might just be something wrong with the CONFIGURATION
It' getting even worse when I keep facing the GREY SCREEN like in PC.
Really, I just want to get my Wifi back and never see that GREY SCREEN again
Please help

The brand name may be different, but the software, or the device, is causing the panics. I suggest you either get the built-in Wi-Fi fixed or consider buying a new computer. If you don't want to do either of those, try another USB Wi-Fi device.

Maverick and wifi issues

Is anyone aware of any particular or specific issues with Maverick and losing connection intermittently with access points / wifi? See link
http://howtoapple.com/mavericks-wifi-issues-fix/
We are experiencing this to some degree with our MACs primarily on Maverick.

Hello RT91,
Thank you for the details of the issue you are experiencing with connecting to your home network using an Ethernet cable or Wi-Fi on your MacBook Pro. I would be concerned about this too. I found a couple of articles I recommend for this issue.
First, I recommend reviewing this article:
Mac OS X: Troubleshooting a cable modem, DSL, or LAN Internet connection
http://support.apple.com/kb/TS1317
This second article has some additional steps specific to troubleshooting Wi-Fi connections. I recommend the full article, but the section titled "Symptom: My Mac does not connect to the Internet" stands out to me for the issue you described:
Wi-Fi: How to troubleshoot Wi-Fi connectivity

Thank you for posting in the Apple Support Community.
Best,

Mac mini wifi issues

Had my Ipad mini for about a week. At first, the internet connection over my Airport/time capsule( which I bought a couple months ago, so it should be the newest generation) appeared to be fine although, I noticed that the signal bar was always a single to double bar (if that's how it is called). Now, from time to time it even fails to connect.
I am now in my living room in front of my mac mini set, which is itself connected to the internet over Airport/time capsule. The Airport is about 20 meters (abt 65 ft) away. The Wifi signal of my mac mini shows full capacity. My Ipad mini signal bar...it just says" iPad". While (when) connected I also have issues with iPad's ITune Wi-Fi sync. Connected by cable, checked the sync over wifi, removed the cable and Ipad disappeared from the Itune screen. I reset the Ipad, connected and did the whole procedure with Itunes and the iPad icon sticked to the itunes screen for a while but after about an hour disappeared again.
Now the ipad won't even connect.
When this thing works, it is a wonderful item. When it doesn't, it is a source of frustration. Can anyone help to solve this connection problem (resetting won't work) ?
thank you.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Wifi issues after upgrading from Maverick to Yosemite. No solutions have worked.

I upgraded to Yosemite 10.10.1 from Mavericks. Having wifi issue where I can't connect to my home network. It connects for 5 seconds than I get "no IP address", and then the connection drops. A free local wifi connection does work. Any ideas until this issue is fixed by Apple? My home router worked fine in Maverick. I tried all the online suggestions but nothing has worked. Have not downgraded yet to Maverick but thinking about it.

Monitor Issues after upgrading Mac Mini OS to Mavericks

I upgraded my older Mac Mini OS to Mavericks. The monitor always worked fine on Snow Leopard (10.6.8 I think), but now my Hanns G monitor takes fifteen minutes to display anything. Until then it is blank and makes clicking, popping noises every 3-5 seconds. After it comes up, it works fine and all the settings seem to be correct. Any ideas? Many thanks for any help you can provide.

Some more info: the monitor is a Hanns G HC194D and is set for 1280 x 1024 with a NVIDIA GeForce 9400 256 MB graphics. My Mac Mini has a 2.26 GHz Intel Core Duo processor and has 2 GB 1067 Mhz DDR4 memory. The monitor display profile says it was created two weeks ago which strikes me as a bit odd, but I updated the OS well before then and this has been an issue since I updated to OS 10.9.3. I have played around with the cables and the connections are tight, and once the monitor finally displays after 15 minutes or so on start-up or deep sleep, the monitor looks and runs fine.
It seems too coincidental that this problem only surfaced after upgrading the OS for it to be a monitor hardware issue, but I haven't seen any other reports of this type of problem. This is a very frustrating problem, so thanks for reading this far.

Still: Macbook Air 2013 Wifi Issues On Wake-Up (And Partial Solution)

I just got my new MBA 13" Mid 2013 last week (updated to Mavericks), and have been having issues with the wifi for a couple days now. Specifically, when I wake my MBA in the morning, it will have disconnected from my home wifi and will not reconnect again. It can see the wifi (and it did ask the WPA2 password after I deleted the network in preferences), but it will not connect due to a "Connection timeout".
I didn't have these issues with my old MBP 13' Early 2011 (also running Mavericks). Also, this only started after I had fully set up my MBA and replaced my MBP, that is, connected it to the external display, hard drive, etc.
Now, it turns out what I have to do is disconnect my external hard drive and reconnect to the network. What kind of architecture makes something like this even possible? And it's not just me, https://discussions.apple.com/message/23423481#23423481 had the same problem: needing to remove a USB device in order to be able to reconnect to his wifi.
This reminds me that with my old MBP, I had an issue where copying large data volumes to external drives via USB would render the wifi connection unusable. So apparently there is something about Macbook architecture that links USB and wifi.
But why does this only occur after a full night of the MBA sleeping? I guess it would have to drop the wifi for energy saving, which it doesn't do right away whenever it goes to sleep?
In any way, this is extremely frustrating. What is the deal with USB and wifi in Macbooks? I really hope Apple can fix this via a software solution, but to be honest, I don't trust them to anymore. I guess for them this is "working as intended".
Cheers
Nate
PS: Please, do not post any links to "troubleshooting steps I may find helpful". I do not, because they were not.

It turns out the MBA doesn't even have to go to sleep for this to happen.
Today i received a new HDD for my time machine backups, so some data transfer was necessary. I made a 600GB backup from my Mac and an external hdd I use for media files, then i started copying another 500 Gb from one external drive to another (USB to USB).
Now in the middle of this transfer (which is rather slow to begin with at around 46 MB/s) my wifi connection just went out. My iPhone, iPad and Windows PC can still connect to my router, but the Mac tells me to "move closer" to it.
It's interesting that my Mac can no longer see any other wifis besides my own, so I guess it's wifi range is somehow impeded by these USB transfers? How does that even work?
At around 50% the data transfer had come to a complete halt, so I interrupted the process. Two seconds after I had ejected AND unplugged both external drives, the MBA could "see again". All visible wifis were listed again and I could connect without problem.
Is there anyone with a similar experience? Is this a hardware defect or an architectural problem? Why have I had these USB/wifi-issues on two Macbook models spaced lmost three years apart?

IOS 8 WIFI ISSUES 5ghz airplay related! the real workaround here

Ever since upgrading to IOS 8, including IOS 8.01, 8.02 and 8.1 I had the wellknown Wifi issue. wifi speeds dropping from 120mbps to about 2mbps @ 5ghz in within a minute after connecting to the wifinetwork. often i couldn't even surf at all. but the wifi signal was always strong. With every update i was hoping for a solution from Apple but it never came. Tried everything that can be found on the internet. Resetting the network settings. Disabling "wifi networking" under Settings > Privacy > Location Services > System Services. Reinstalling my Ipad from scratch Used different routers and different setups. Automatic ip's and fixed ip's and different dns servers just to be sure. Nothing worked. The only workaround is switching to a 2.4Ghz network. So i was doing some tests and found THE solution, but i don't like it all. One of the biggest changes in IOS 8 is the ability to use airplay without a network. by using a wifi connection in combination with bluetooth. And here lies the problem. I disconnected al my Airplaydevices from my network. Denon AV-amplifier AVR2113, Pioneer wireless speaker XW SMA3 and an airport express. Et voila... My Ipad is back to normal. fast... no very fast internet connection and stable as ****. Just like iOS 7 was. Working with it for a couple of hours now without any trouble at all. But do i connect one Airplay device to the network the wifi is not stable anymore and extremely slow again on my ipad air. My Macbook running mac os x mavericks doesn't have these issues, neither does my iphone 5S. and they are also on the same 5ghz network. So I can create and recreate the issue and create a work around... Apple please come with a solution that makes me able to use airplay an ipad (on ios8) on a 5ghz network! like in iOS 7!!!!

I'm just going to throw something different into the mix. Could it just be that different Wi-Fi networks may use different ISPs and each ISP will have it's own configuration settings?
For example, if you have an iPhone on Cellular Network 1 and send an email, it'll use the SMTP server for that network. If you're using your home Wi-Fi you'll have the SMTP server for your ISP in your iPhone's settings, and that's what your iPhone will use when sending an email from home. But if you're accessing a different Wi-Fi network somewhere and it's using a different ISP, then it'll have a different SMTP server. So, sending an email for example won't work unless you turn off Wi-Fi and force your iPhone to use your Cellular Network instead (because it'll have the SMTP server for that network).
Now, the example above is specific to email, but I'm just trying to think outside the square a little compared to the other responses here.
Hope this helps you progress to a solution.
Joe.

I reinstall the Yosemite due to the wifi issue, when finished, the iMovie was not installed, I try to download it from app store, but it's not free. How can I get iMovie back?

I'm using a mid 2014 13" rmbp. I reinstall the Yosemite due to the wifi issue, when finished, the iMovie was not installed, I try to download it from app store, but it's not free. How can I get iMovie back?

It's something to do with the main user account (not iTunes account) on my Mac because I logged in with another account and it downloaded fine, I installed it on the HDD and even though the date in App Store was 16th October 2014, it is the full installer of 10.10.2.
To try to resolve this problem, I have copied the installer app elsewhere and deleted it but App Store still will not allow me to download it with my main user account yet just allowed me to update iTunes.
I had a brainwave last night that it might have been related to me changing the default downloads folder to one not on my boot drive (to save disk space on my main boot drive) but having changed it back, tried again, rebooted and tried yet again, deleted my App Store preferences. nothing has worked.

My brand new mac pro always had Internet connection issues at school. WHY is that? I see the school's Internet working perfectly fine on other PC's, but there is never a day where my mac doesn't have Internet connection issues at school. How do I fix it?

I got my mac pro in the middle of August. School started the week after. Internet was working perfectly fine at home. But at school, I never had a good connection. Sometimes on the good days I get a connection when I'm sitting at the exact spot in class I always sit at. It's ridiculous and it's frustrating. I invested my money into this laptop and I'm beginning to regret it. I thought it was the school's Internet, but I don't see Internet issues with other PC users. It's most frustrating on registration days and I'm trying to register for my classes before it gets taken, but again... Internet connection issues. It's random. Majority of the time, it doesn't work at all. I've done Network Diagnosis and turning WiFi off then turning it on again. I've done everything I could. I put my money on this laptop and it was a lot of money. I could have bought an 800 dollars laptop and I would have Internet connection anywhere on campus. So, I don't want to continue everyday to regret on buying this laptop every time I try to connect to the Internet at school or Starbucks or anywhere else. How do I fix this? What's the problem ?
At school, I heard this guy had a problem with Internet connections too and he owned a new mac book pro. He said something like Apple messed up on something, but he fixed it. If I knew mac book pro's had these issues I wouldn't have bought it in the first place. It's freezing on me every other day. It's ridiculous. But what concerns me the most is the Internet connection. So someone please tell me what can I do next to prevent the problem? Am I doing something wrong maybe?

Hi Kevin,
I'm using an XLR input mic which is connected to the phantom power enabled XLR mic socket on a USB M-Audio M-Track. The M-Track is connected by USB to the Mac Pro - so effectively I've got an M-Audio USB soundcard with a mic input. I've also tried a microphone that is a straight XLR to USB cable (guessing with some soundcard chip buried in the usb plug) but that also yields the same effect of bad latency, intermittent quality, stuttering and repeating and echoing (without the speakers on during record so its not feedback).
The mic works absolutely fine with other recording applications I have on the mac at the moment - albeit non-adobe ones (tested it on the EasyAudioRecorder - and it lives up to its name. it's easy)
I will try with Audition and report back, but sitting here right now I can imagine it would work fine with audition too - it just seems to be the way premiere is set up for recording into the timeline is a bit sketchy. I'm willing to accept it might well be a quirk with the new Mac Pro trashcan - I'm not weighting all the woes on premiere.
Any thoughts or am I out of luck to sit with my fingers crossed for a fix in the next round of updates?
Nathan.

MBP WiFi issue after updating to 10.8.5

I have a Macbook Pro late 2011 and used OS X 10.8.4. Last week installed Windows 7 with latest BootCamp. everythings was fine! Then I updated my Mac to newer version (10.8.5).
Now WiFi just works on Windows and Mac does not find any WiFi networks.
My WiFi security is WPA2.
Any one know how do I solve this issue?
Regards,

Back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

Ongoing WiFi issues and Apple Support's lack of support!

Hi All,
I bought my MacBook Air in July/August 2012 (i7, 8GB RAM, 256 GB HDD, Mountain Lion). Since the first day, I have had issues with wifi connectivity. My primary use was at the university in Australia, where I had frequent drop outs and at times no connection at all. the university does not officially support Apple products and I was stuck with Apple support asking me to check with network administrators. I was also advised to re-install the OS, reset PRAM etc with no improvements. Then I had a 4 month stint as an exchange student in an Indian university. As i was not using my laptop at the university, I couldnt monitor the WiFi connectivity in these 4 months. Once back in Australia in January 2013, the issue surfaced again. Multiple conversations with Apple Support led me to another 4 re-installations and replacing my router with an uber expensive one. The reasons given by Apple were either the router's quality or interference from other networks. The new router supported 5Ghz band and had no intereference what so ever. I started to notice that the connectivity is far better with the wifi signal showing full range, but internet does not work. All is well if I am sitting right next to the router. The minute i move 5-8 metres away, Internet becomes super slow (from 12-14 Mbps to 1-2 Mbps on speedtest.net) and eventually does not load. At the same time, all other devices, including my iphone 5, ipad 2, ipad mini and other PCs in the apartment works perfectly fine.
On speaking to Apple Support, i was asked to conduct SNR checks and found out that the SNR readings fluctuate like ****. From 1-2 to 25-30. The Signal strength on my MacBook Air stays at -75dB to -65 dB. Armed with this info, the Airport card was replaced. But the issue still persists. The MacBook Air is presently at Apple waiting to get its display (antennas are embedded here) replaced. But I have lost total confidence in Apple. Is there anyone who had similar issues and found a stable solution? Other symptoms which may be connected are Mail becoming nonresposive intermitently, Power Nap function not working, battery life never more than 4 hours.
Apple Support has been appalling in a very courteous manner. Even though the commincation and care they took to talk to me, the issue hasnt been solved and its been 11 months!!
Any comments, advices and support will be appreciated.
Thank You!

I am sorry, maybe my comment was vague. I am an engineer too albiet in the medical devices sector. Problem for me is that, I have been talking to Apple for about 11 months now. If you know where I live and how far the Apple Store is, you'd understand my frustration. I have been accomodating so far and do love the customer service experience I get from Apple. I am a proud owner of 2 iPads, an iPad mini, an iPod classic, an iPod Touch, an iPhone 4 and an iPhone 5 besides the MacBook Air. They are the most courteous and receptive Customer Service Reps out there. But all the courtesy does not hide the fact that my MBA is 11 months old and still having an issue starting 11 monthds ago. I had taken this machine to the stores numerous times. With the last week, i was getting to a point where I felt I have done enough to try everything except replacement of the machine to try fixing this issue. But now, Apple wont play ball. the rep said, i quote "your machine is almost a year old and you cant expect Apple to replace it". they have support call documents to prove that i have been talking to them about the issue since 11 months and to top it all, I have also purchased the $279 extended warranty. At the time of purchase the rep promised me that 'I would be send a box containing a loan machine while yours can be sent to us and fixed'. if you go through my posts here in mac forum, I had raised the issue here as well.
Now coming to the question, I have exhausted my options with Apple support and wanted to know if anyone else had the same issue and found a fix. With that maybe i can stop pulling my hair apart - realistically, stop myself from making another long trip to the Apple Store.

For all those out there with Iphone5 WIFI issues,Please READ THIS

I pre-ordered my iphone 5 (Black) got that last week. Quickly backed up my Iphone 4 and Restored my iphone 5.The first thing i checked to see is connecting to my WIFI network at home. And i kept getting a message "UNABLE TO CONNECT TO THE NETWORK". I had the iphone 4 aside and i can see iphone 4 is connected just fine. So are my laptop, Ipad and other devices.
So what is different in Iphone5?
After couple of days of head banging, and phone calls with apple support. I finally gave up and went to a apple store , they said, They have not heard any WIFI issues and my case was the first , However to keep me happy they said they will replace my device, But if have the same issue ,they will NOT be able to replace it again. And they even showed me the new iphoen connects to their "Non-secured" apple WIFI network.
So i take the new phone home, and the first thing i try is connecting to WIFI.And i still get "Unable to connect to the wifi network ".And i still can see Iphone 4 working fine and connecting to the same network just fine. With the second iphone5 also not working, I realized it is not hardware, but something surely changed with WIFI in iphone 5. I have a NETGEAR router with its latest firmware installed(2.0.26). I then downgraded my firmware to 2.0.21, then gave a shot.
BINGO..Iphone 5 works fine connects to wifi.and so is my iphone4 too.
So for all those users out there, the fact is something changed in iphone 5 WIFI algorithm. And if anyone really disagrees with me on this, I am going to post a video to demonstrate on YOUTUBE. I believe it is completely UNFAIR for apple to now ask you Upgrade/change your router or its firmware. And it is not fair for router companies to Fix anything to make their firmware compatible with iphone5.
So iphone 5 Users, Please lets us all push for a fix on this issue. WE WANT FIX.

I can't tell you how frustrated/disappointed I was when this exact situation happened to me. I upgraded my wife's iPhone 4 to an iPhone 5 just to find out that it wouldn't connect to my home wifi but would connect everywhere else. Guess what...
I found a fix!!
On you iPhone go to Settings, General, About, scroll to "WiFi Address". Now stay there.
Log-in to your modem thru your web browser via IP Address. (Keep in mind, I use a 2Wire modem, yours may be different) Clicked "Wireless" for wireless settings, scrolled down to "MAC Filtering" and clicked "Edit Allowed/Blocked Device List". At the bottom, there's a field to which you can manually enter a MAC address to you allow or block. If you're using a different modem with different menus/options, just browse around til you find a similar option of manually adding MAC addresses for access or blocking.
MAC Address = Wifi Address. See where i'm going with this?
Type the WiFi Address from you iPhone in the MAC address field, click "Add to List". If MAC filtering is enabled, it'll be added to the BLOCK list, simply click on the address, and click the double arrow pointing towards the ALLOW list so it'll transfer lists to where you want it, then click save.
Now go back to your iPhone and attempt to re-connect to your wifi network as you normally would & voila!
This worked for me, i hope it works for you as well.
