PLEASE DON'T POST ABOUT HOW THERE ARE ALREADY THREADS ABOUT THIS!!! that's why I am here, I have scoured up to 10-12 pages deep on every keyword I can think of on google, all I find is unrelated and most often severely dated blogs. I apologize in advance for any potential redundancies as I am very upset right now. Hardware: MacBook Pro MC723LL/A Clear 4g MODEM sometimes, Netgear WGR614 v8 Wired or wireless I cannot achieve a stable internet connection to my MBP. It almost seems that while browsing, firefox it will disconnect momentarily, royally screwing with most pages and causing firefox to spin and say connecting on the tab indefinitely. If I go highlight the URL and hit return once (sometimes twice or three times) the page will suddenly respond. Its as if firefox is missing the "connection window" to access the site for just a split second, then it isn't able to load anything at all until re-submitted. It is really bad when clicking a link (versus manually entering an address) Safari and many of my add-ons that require internet in XBMC are just as bad. SpeedTest has yet to show me speeds under 1.25 Mbps Dl whenever tested, usually averaging 3.5 Mbps or higher. Transmission is also being negatively effected as a result, I can almost fully saturate my connection, (~500kBps) but only for a moment before it drops to ~68kBps (or similar), its really all over the place. All in all, My connection when ran through my MBP is garbage. Wired or Wireless, doesn't matter. It takes three attempts to load the speedtest page, but when it loads my connections comes in at 3-5 Mbps (more than suffcient browsing speed) My instinct tells me its the MBP but that is only because I "upgraded" to the $2199 15in early 2011 from a base $1199 13in 2011 and this POS has had more issues than my 13in EVER did (13in never had one issue, 15in already has a new Logic board, my processor loves to show only 50% and get the fans spinning like crazy when NOTHING is running it activity monitor and my fan is F'd up, god knows why. it's running off-balance and will start clicking after some use, which they didn't replace when they fixed my logic board even though I have a video of it at its loudest that I showed the "genius" and you can hear it off balance at its quietest) and I know that connection issues are all over 10.6.8 and Up If it is the MBP what are some things I should try and/or links to sites/blogs that might help. Is it OSX? I have recently installed XBMC, LOGIC9, PT9 and my plug-in collection. Are there any prefs or anything i should try to reset. I really don't think its FireFox but I suppose as it is set as my Default brower it could effect how XBMC loads a page/video stream but like I said, safari is no faster. IF YOU NEED MORE INFO TO HELP PLEASE ASK BEFORE I PULL OUT MY HAIR TRYING TO BROWSE THE INTERNET!
