macbook pro no internet but full wifi signal

"..On my guest account ( safari only account ) internet works just how it should. on the same network...."

Ok so it's a specific problem with your account, and the problem seems to be dns resolution.

You may need to flush the dns cache

Or maybe someone has fixed your ip or dns or gateway addresses up for the old router that had a different ip address range. That would affect you but not guest account.

See "my macdoes not connect to internet" in http://support.apple.com/kb/HT4628

Hi Leander,

as peter_watt said there is probably a glitch in your DNS configuration. Check the DNS settings in your router first. I don't know your Cisco router so I cannot help here. Use the IP "8.8.8.8" which is the Google DNS server. It should always work.

Second, on your Mac open System Preferences -> Network. Choose your connection (Wi-Fi or Ethernet) and click on "More Options" or similar at the bottom right of the window. A new window opens. Click on DNS and make sure to add "8.8.8.8" as DNS-Server.

Click "Ok", the window closes. Then click on "Use".

I had a similar problem and this worked for me. Hope it will work for you too....

Log in to your router using Safari (Open 192.168.0.1) See this manual on page 29. Follow steps how to log into the Administration pages. Then proceed to page 36 of the manual. Here you find how to enter the DNS entries.

Hope it works.

same here!!

after the last update, on my retina MBP 10.8.2, the wifi signal of the OS shows allways full, but the signal reception in the retina is so awfull that I installed the wifi Signal app, that shows what's going precissely and says the truth.

My problem it's not because some soft interfiering, I mean, 30 mts from the router, I didn't get conection, of course, normal BUT mac os x wifi signal says it's full!!! 😮

I think Apple did it again like with the GPRS/3G signal of the iPhone, that they updated the iOS to make it shows allways full signal.

where is the FCC???!!

If you get wifi but can’t get Internet without repeated disconnects and slow loads, you need to edit your Locations in Network Preferences. If it doesn’t make sense that your modem and router work, yet your functioning Airport card can’t deliver content, according to the Genius Bar expert at Upper West Side, it’s like getting an envelope in the mail, “but nothing’s in it.”

In Edit Locations, from the drop-down he clicked the “+” to create a new Location which he named “Automatic” (any name will do). My old locations somehow got corrupted. The new location setup new a new default WiFi (and Ethernet and FireWire) and connected to the Internet immediately. So far, I haven’t had to re-enter any passwords. No PRAM zaps, reboots, and modem resets (didn’t work anyway).

MY FIX... Basically i could get on the internet in certain rooms of my house wierelessly but not others, my ipad could cennect all round the house. As it was infuriating i was considering buying a booster plug but then tought there is full signal it should work, this is when i stumbled accross the realisation it might be the channel of the router, the more reading i done the more it made sense, i went from channel 1 to channel 11 and now i have perfect internet everywhere. Because im in a residential area there are loads of wirless networks all probably trying to use the same channel! try changing your channel guys, i has the ip address problem, simply wouldnt connect problem, connected but no internet problem and they all got fixed by this ! good luck !

The 8.8.8.8 DNS works for me. Thank you, internet people! Man, that was frustrating.

Thanks pburley01The creation of a new location fixed the issue for me.

Did u upgrade to yosemite, although old OS X are starting to loose functions, yosemite on older systems in every case i ran into is a royal nightmare,, my iMac that ran beautfly until last year, finally crashed. I believe there are major problems at Apple. My brand new macbook pro was unusable for several months. I found using diagnostics on your own will be the best way to fix it at your location. System pref to network make sure your wifi is first on list, and underneath check all boxes where system admin is required for any change, and empty cache. This is the start to setting your wifi up. There are others till I figure this out, that have further steps. Mine after sitting with window open started loosing wifi again, but will wake up after checking into network, and be fine. Which is a lot better han it was

Thank you so much! It worked great for me.

Thank you! I was on the phone for 45 min. with AT&T with no help. Tried this and was browsing in 2 minutes!
