After stringing along my shitty, homemade wifi card for the past three years, I decided to get a real card. While my homemade card was getting about 3mpbs, immediately after install, my TP-Link WDN4800 was reaching 25-30mbps in the exact same location. It was fantastic. For about a day.
Then, something kind of weird began. I started to lose internet connection while continuing to receive a wifi signal. The signal was still full, and there was no exclamation wifi icon, but I couldn't access the internet.
I only noticed it once the first day, in the middle of a movie I was streaming from my Plex Server on the same build. The wifi signal was still there, but no information was being exchanged. Turning wifi off and back on fixed the problem temporarily, but it steadily became much more frequent.
My Build Basics:
OS: Lion 10.7
MoBo: Gigabyte z68x-ud3H-b3 (Still on BIOS F-8...I think...)
CPU: Intel Core i7-2600
Wireless: TD Link WDN4800
Router: Netgear WND824N 150
What I've Tried So Far:
Turned airport on and off (constant temporary fix)
Turned router on and off
Reset modem
Changed to each of my wireless channels (1-11)
Deleted all old wireless locations
Created a New wireless location
Deleted Preferences
Commanded Terminal to "ping google.com" to maintain activity*
Renewed DHCP Lease
Created Manual IP address (failed multiple times, looked like it was working, then signal still dropped and I got kernel panic on startup)
Turned off / Reset all Little Snitch rules.
Moved my wifi card below my GFX card, bottom slot, between base fan and GPU fan
Changed MTU size
Disabled IPv6 – worked for at least 6 hours. I thought I had the problem solved. Then I woke up, the computer had lost connection overnight, and the problem had returned to normal.
*Once I realized how useful this was, I repeated steps 1-7 while pinging Google, just to know exactly when I go offline, and gauge approximately how long I was online.
Further Thoughts/Observations:
All of my other devices maintain an uninterrupted connection to my router (2009 Macbook on Snow Leopard, iPad Air, iPhone 5c, Asus Transformer Tablet running Jelly Bean, Motorola Moto X on KitKat, and my Roku). I assume the Router is fine.
What's most interesting to me, is that even after my Hackintosh fails to connect to the internet, my router still sees it as an active device. What the hell?
On each of my failed trials, I checked my connection strength before failure, and speedtest.net consistently had my download speed between 27-30mpbs. Many times (though not always), my internet would cut out during or just after the speed test, and there was no steady drop in connection. It's sudden and immediate.
It hasn't happened while I'm streaming videos from Youtube or Vimeo yet, though it does happen while I'm on my Plex server (which has been disabled for the tests since).
My station at work is a 2009 MacPro Tower, also running Lion (One of the reasons my home one still runs Lion, and why I have a hack in the first place). I installed the card in that box to see if it works, and there's been no hitch after one full day of running and constantly pinging google. I assume the card is fine. However, I don't know what type router my work uses. I do know the signal here is shit (5mbps). It does make me think this is a Hackintosh issue.
Perhaps I'm not very good at using Google (other than constantly pinging it to check my connection), but I have researched this problem. Many of the boards don't have a solid solution, and most seemed to end at "Create Manual IP Address." I have not gotten that to succeed.
Next Steps?
I don't see anything on Multibeast 4.7 that I can run to improve WiFi. Perhaps I missed something?
I didn't see anything in my BIOS that would effect my WiFi card, but I do get a little lost and scared there sometimes.
I can't really test a 5Ghz wifi connection, and I'd rather not buy a new router if I don't need it, but could that be a problem? Or any router?
I've clearly been reluctant to update. My computer runs very well, and I don't need my interface to look like an iPad. This is my last resort, but if you all agree it will fix the problem, I will dive back down that...
Thanks for taking a look at this giant wall of text. I've tried to be as thorough as I can, but of course let me know if you have any more questions about my build and what I've tried.
Perhaps I'm missing something obvious or simple, and perhaps I'm thinking about the problem wrong. All input is appreciated, I will be eternally grateful for anyone that can solve this problem. And I mean eternally, like Chewbacca with Han. Except metaphorically, not literally...
