Unable to reinstall Mavericks (unable to join wifi)

Morning,
I was trying Yosemite for some weeks but I wanted to unable it in order to restore Mavericks. I restarted and used disk utility to erase the system then tried to install OSX again. However, the installer refuses to join any wifi network (ADSL gateway, wifi hotspot I created from another computer and iPhone connection shared). The problem is not related to the wifi gateway I used because all the wifi hotspot I could reach (WEP, WPA and even no encryption) give the same error:
"The wifi network "..." could not be jointed. Try moving closer to the wireless router.".
I attempted several reboots (shutdown, then restart) without success. I plan to connect my computer to a networked router tomorrow with my USB adapter but I would like to know if there is another way to bypass this issue with a wifi connection.
Thanks in advance
Thierry
(Macbook pro (late 2013))

Fixed the wifi problem using terminal (networksetup -setairportnetwork en0 SSID Password). Currently, I can use Safari or terminal to get access to Internet. However, I confirm this is now the yosemite beta installer which causes my problems (now, the error is "An error occured while preparing the installation. Try running this application again.").
How can I revert back to Mavericks ? I have a external hard drive with OSX Mavericks (but the HDD is FAT). I tried cp -R to copy the installer back to /Applications but I receive a lot of "No such file or directory" messages.
I would like to create a USB stick to reinstall but I'm not sure its possible since my Mavericks installer is hosted on a FAT formatted HDD.
Anyone got the same issue ? Thanks

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 drooping 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

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Can there be a hardware issue on the iPad that causes you to unable to join wifi networks or only if you are within 5 feet of routers?

I used to be able to connect my iPad to my house wifi network walking all over my house then one day it stopped. When i tried to connect to my network I would get an message saying "Unable to Join network". I found that if i was within 5 feet of my router it would connect and work just fine. At the same time I tried it at multiple other networks that I have before (girlfriends and other friends houses) and could not connect with same issue. Only place I can connect is my work wifi.

Unable to join wifi

Hey ! Guys
I wanna a help please !
The iPad of my brother has been unable to join our wifi and the password is right ?
What should I do ?
Please, answer me in the quickest chance .
Thank u

restart all devices, modem, wi-fi router and iPad (Hold the home and sleep buttons till you see the Apple logo).
then try to connect again.

Unable to join wifi at home

for some reason my iphone4s stopped joining my internet at home. I've restored the phone and network settings and still when i try to access it it continues to say unable to join network? yet my boyfriends phone (droid) is able to connect to it just fine.
help!

Barring the possibility that your boyfriend changed the WiFi password and is playing a joke on you try these steps:
If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPhone. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
First, test your iPhone on some other networks: a friends, Starbucks, Barnes & Noble, etc.
If it works well there then the problem is with your network. Try restarting your router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
If your iPhone does not function well on other networks it possibly has a hardware problem. Contact Apple or visit an Apple store for evaluation. They can provide a replacement if your iPhone is bad.
If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

Unable to join WiFI network

Can anyone help? EDGE is working fine for me, but I want to go a bit faster when I an at Home and connect to my mac's airport. Do I have to have a airport base station to accomplish this? My IPhone is reconizing my mac, but I keep getting "unable to join the network 'myname's iMAC G5'". I am getting a strong signal (from the airport drop-down menu) and I have "use interference robustness" turned on, but still unable to connect. Any advice? Thanks

Allan is right, if your iMac G5 is sharing it's network connection, that is what the iphone is picking up.
If this is the case, on your iMac, try going into your system preferences > sharing and turn off internet sharing.
Then power off your iphone and power cycle your airport. Then turn your iphone back on and check to see if the iphone sees your airport network.
If it does not see your network, the airport might not be broadcasting the network name. This can be set up for security reasons.
Go into settings > wi-fi and choose other. This will allow you to put in the name and password of your network.

Macbook air unable to join wifi network

I have a brand new MacBook Air and am new to Macs, but have a very good understanding of PCs. I constantly have to reenter our wireless security code for Wi-fi. Now I am receiving a message that says "the computer was unable to join the wi-fi network you selected". What am I doing wrong?

After a 30 minute phone call with Support, nothing worked still! In the end he suggested changing the channel of the wireless router/modem. I tried to do this (after research online on my imac) and then lost all internet connection. The router/moden no longer worked at all! Then had to call the support line for the router; spent another hour or so trying things, but to no avail. In the end have had to buy a new modern modem router (Belkin Dual band N+ PLAY N600 DB) and so far ......................it's working! But we only bought it this morning. Will report back another day with an update!

Power the iPad Off, then power it back on. Now reconnect to the network and retype your credentials.

HT1731 Unable to join wifi

I am not able to join a wifi network in client mode from my airport express. This used to work when my main router was another airport, but not now when I use a d-link.
What is wrong?

The D-Link router is using different settings than the former AirPort, so the Express cannot join the wireless network.
The Express will join the network providing that three conditions are met:
1) Express must have the same wireless network name as the D-Link network
2) Express must use the same wireless security settings as the D-Link network
3) Express must use the same wireless network password as the D-Link network

Ipod Touch 4g unable to join wifi network

We have a new Ipod touch 4g. We have a wifi router in our home. We have to other ipod touches and two iphone that log on with no trouble. I have updated the firmware software on the router and updated and restored the ipod. What else can I try?

The problem could be caused by a firewall in the router. For reasons that I do not understand, that will affect IOS (iPod/iPad) communication but will not affect computers or other devices.
You will need administrative access to the router. If a firewall is present, turn it off and test the iPod again. If it works, turn the firewall back on but weaken it a notch and test the iPod again. Repeat as required.
Edit...
Two other IOS devices are functioning properly. This solution is not valid. Sorry.

IPhone 5 Wifi Passwords not working: Unable to Join

I have an iPhone 5 OS 6.0.2 and am unable to join wifi networks except the one at home. What should be my first step? Restore from backup or reset network? How do I reset the network? (I hesitate to do that in case I then have trouble joining my home wifi.)
Will reset network also reset my carrier's network?
When I got this phone I used my 3GS iPhone to transfer all data.
When I first got my iPhone 5 it had trouble even connecting to my carrier's network. I would get a no service and then it would connect to my carrier after a few seconds. I got a new iPhone and it did the same thing and it is still doing it. Is my wifi issue related to this issue?

Go ahead and try to reset your network settings first. You can do that by going to Settings>General>Reset>Reset Network Settings. This will make your phone restart, and delete any wifi networks listed in your phone. After your phone restarts, see if you can connect to your wifi at home. If you can, try those other networks. If not, you may want to try backing up and restoring your device. If THIS fails, you probably need a repair done through your warranty.

Unable to join the network on Iphone 4

I am unable to join WIFI network in my house all my computers are able to join but when I try on my phone I receive error message Unable to Join the Network. I have tried reseting network settings and rebooted phone. Nothing is working. Anyone have any advice.

Hi mcctigger,
I know it can be frustrating when you can't get on the internet.
Sounds like you've tried a few things, but I would suggest you follow the steps in the article below in the order presented:
iOS: Troubleshooting Wi-Fi networks and connections
Basic troubleshooting
Tap Settings > Wi-Fi and turn Wi-Fi off and then on again.
Verify that you are in range of your Wi-Fi router or base station.
Confirm that your Wi-Fi router and Cable/DSL modem are connected to power and turned on.
Check whether other devices (portable computers, for example) are able to connect to the Wi-Fi network and access the Internet.
Update your Wi-Fi router to the latest firmware.For AirPort Base Stations, refer to this article for information about firmware updates. For third-party Wi-Fi routers, check the manufacturer's website for details on updating your firmware.
Restart your iOS deviceHold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.
If you are still experiencing a Wi-Fi issue after trying the above, choose the symptom below that closely matches your issue:
If you're unable to join a nearby Wi-Fi network
Try restarting your Wi-Fi router by turning it off and then on again.
Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
When joining an 802.11n Wi-Fi network, ensure that your router is properly configured. See this article for more information.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings, including passwords, VPN, and APN settings.
Hopefully you will be up and running again soon!
