My iPhone connects to my Wi-Fi, but my Mac won't?

My Wi-Fi on my Mac book has been working fine the last few weeks. Sometimes it cuts in and out, but usually when it does it affects everybody's connection. Tonight I'm the only person who can't connect to the Resident Hall Wi-Fi. The internet keeps trying to connect but the airport has no connection bars. Under network settings Wi-Fi has a yellow bubble next to it. Any suggestions?

Try to reset your router or update the Mac's wireless network driver. If it still couldn't work, check more solutions here, http://www.mywifirouter.me/topic/six-useful-ways-help-to-solve-wifi-problems/

  • Wi-Fi connects but internet doesn't work? I'm staying at a hotel this week. There's free Wi-Fi. My friend's phone and laptop are connected and working, as are my sister's. However, both my iPhone and my iPod are "connected" to the network, but the internet doesn't actually work. It's very stressful. What do I do.
  • What should I do so that my iphone connects to known Wi-Fi automatically? So recently I reset my network settings as someone said that I should do that to lose a problem (my phone was giving me two text alerts when I've only received one. Yes I checked the notifier already which I put to never) so that problem is solved but now everytime I get home, I have to key back in my Wi-Fi password whereas last time it would automatically connect. I've been resetting my network settings a few times but nothing has changed.
  • What is the device called that connects your iphone to your car stereo to play music?

  • Sony Xperia you won't connect to home Wi-Fi but connects to everything else? My brother just got his sony xperia you and it won't connect to our home Wi-Fi. My iPhone 4s, my sister's iPhone 4 and my dad's HTC desire all can connect to our home password protected Wi-Fi. However, my brother's sony xperia says connected with limited connectivity. We went to the local mcdonals and my cousins house and all those connections work. What is wrong with our home Wi-Fi?
