Apple Event: May 7th at 7 am PT
After upgrading to Mountain Lion my Internet is slowed to a stall using both Safari, Firefox, and Chrome. I do not get a failed page error, but the progress bar never finishes loading. I repaired permissions, reset PRAM, and fsck'd.
I posted this using iPad.
MacBook Air, OS X Mountain Lion
I also created a new network Location. No change.
My internet has also slowed down to a crawl. Pages will start loading and never finish. The only thing that helps temporarily is closing my wi-fi and reconnecting. I hope a patch is released soon. 😟
Macbook Pro Mid 2010
Airport Extreme
Connecting via wifi
I too am having the same problem. The internet seems to be intermittingly working. I am going to try to plug straight into router(ethernet/no wifi) to see if it's an issue with wifi in Mountain Lion. Will keep you posted.

Same thing here.
Macbook Pro Early 2011 w/ Mountain Lion
4GB RAM
Connecting wifi to AT&T u-verse box
ISP is AT&T in Santa Clarita, CA.
MBP is running at about 1.4 Mbps download.
My old white 2006 Macbook with Snow Leopard is running 11.46 Mbps download on same network, at the same time.
And it's not just the browser, because Apple Software Update is telling me 10-12 hours to download 1.4 GB of data.
My internet is much slower too.
3 month old Pro with 8GB Ram and 512GB SSD.
Have had a few failed downloads from the App Store for the first time.
BT WiFi in the UK.
Are all of you trying to connect to the internet right after you have installed the OS or are trying to use programs or other items?
When Mountain Lion is installed and is booted for the first time it goes through an indexing process to index all of the files on your computer.
That may be the issue you all are having.
Thanks,
Andrew
It seems to be a wifi issue. Ethernet works fine with Mountain Lion.
I am having the same problems. Downloading is going very slow, and safari is not going anyware.
I do think it's a wifi problem.
Macbook pro 13 inch late 2011
I don't think it's the indexing. I let mine sit around most of the day while I was doing other stuff. It wasn't until almost 12 hours after the original install that I started trying to download updates and noticed the massively reduced speed (1/10th normal internet speed).
However, I am noticing that web pages open up in Safari at just under the speed they did in Lion. I just can't download anything. I finally downloaded the iPhoto and iMovie updates on my old white macbook and brought them over on a flash drive just to get them done.
Something's wrong when the internet worked fine right before the install (it took 45 minutes at 6am PST yesterday) and today I've got to pull a 6 year old mac out just to download updates ...
OK. I tried connecting via Ethernet directly to the router, and I am having the same issues.
It is not WIFI.
I went to speedtest.net and had two very different results.
1- REALLY fast 30Mbps download / 1Mbps upload(which is normal)
2- REALLY slow 0.4Mbps down / 1Mbps up
So, the upload was the same, but the download speed was either all the way on - or nearly off.
Not sure what that means, but this is pretty frustrating.
Do Apple devs/reps ever reply to these issues? Needing an answer quick!

Speedtest.net is not working correctly. The results always vary considerably. Try the speed test of your internet provider (AT&T etc.). It's much more reliable.
In Network Sys Pref, create a New Location.
Setting up a new location was one of the first steps that someone tried with no success. I am going to give it a go cause I need to sort this out ASAP, and will keep ya'll posted.
When the the internet connection works, it is blazingly fast. Which is great... if it only worked!
I just set up a new Location in the network prefs. Same issue. It does the same everytime for me:
The first site I load is incredibly fast, then the second site is slower, and the third site is pretty much a no show.
It's as if it starts out perfectly then quickly falls over.
APPLE PLEASE HELP!
At least in my neck of the woods, AT&T's speedtest was pretty accurate with speedtest.net.
2011 Macbook Pro w/ Mountain Lion - 1.8 Mbps download
2006 White Macbook w/ Snow Leopard - 11.4 Mbps download
Both uploaded at about 1.45 Mbps give or take a few.
The varience between AT&T and speedtest.net was only around 0.5 Mbps.
Almost feels like something is throttling the download speed in Mountain Lion.
That's strange ... I have a brand new MBP Retina (16 GB, 2.7GHz): Wifi is working extremely slow, so this morning I bought an adapter and I connected the devis via ethernet. Since then the speed is as good and fast as Lion: 51.30 Mbps download and 5.12 upload (AT&T Roadrunner, Manhattan).
10.8 caused internet connection to slow to crawl
