Internet Connection Problems G73-3DE Intel 6300 WNDR 3300

Hey guys, haven't been around for a while but i'm literally close to topping myself, got the most irritating problem with regards to my wireless.

So I have a G73-3DE, basically stock, minus the 6300 card. I have a 5ghz network setup in my house so I thought I may as well take advantage of it.

God has it been a waste of money so far.

I first noticed problems with JDownloader, which I use to manage pretty much ll my downloads. My work requires me to upload a lot of stuff to file hosting websites and download from them as well, between me and clients, in order to work out kinks in projects (i'm a video editor/SFX artist).

Now, JDownloader would show up a "Lost connection, wait x minutes" error at seemingly random times on all files. It would continue downloading the next part, but that would again, fail at a random time. After posting on the JD forums several times, including my logs, They recommended I drop my max conn. down to 1, from 2. I did this, even though my mac, in the same house, never had this problem, and my internet speeds haven't changed.

Now, in stead of just losing connection, the downloads simply freeze. The speed stays constant for 1 minute, but the progress bar doest move and no data is transfered. Then, it will pick up again, after another random amount of time.

I was convinced it was JD until I realized this sort of happens on Youtube. Buffering a video on any quality, will last a random amount of time, before it just stops. Looking at the network activity it will e buffering along at 14000kps~, then just crash at inconsistent times.

Now, I have noticed even browsers downloads in Chrome do this. Downloading any file from anywhere, it will download for anything from 5 secs to 5 hours, before the progress bar stop moving, and the speed slow starts to count down 1kb at a time.

So if anything, JD was HELPING me. As in, all other aspects of my internet just lose connection for no reason, even though it says i'm connected, but then never carries on doing what it is doing. JD however would star the download up again eventually.

So as a prolific downloader/uploader/youtuber this laptop is now worthless.

Driver wise, after my fresh install I downloaded the only 6300 related thing from intels website (read:no stand alone drivers) and it was their "MyWiFi" utility. T His let windows see the card, and everything worked, but with this problem. I asked Ken from GenTech about what driver he originally put on it (when I MAY of had this problem, or MAY NOT, never tested it before I wiped it). He said he used the 6250 driver on the Asus Driver disk. I am now using that with the same problems.

So sorry for the wall of text, but I have exhausted everything I can think of and am going crazy with frustration.

If theres anything more I can provide/answer please let me know, I really need you guys here lol.

Update:

I'm literally sitting 10 ft from my router, no walls between us. I do only get 4 bars sometimes on 5gz though...

I forgot to mention this is the case on both the 5ghz and 2.4 ghz channels.

Yup that's the right encryption.

I re-installed the drivers from the website, which is the exact one I first installed with I think, and low and behold...no difference.

I'm using a NetGear WNDR 3300 which get it's internet conecction from a D-Link something or other, it's the standard router for Sky over here in the UK. None of the other 4 PC's/Laptops or either of the 3 xbox's, ps3 or Wii have problems. Just little 'ole me.

I have seen a few funny instances in some of the router logs, but my networking skills are far to under devloped to make sense of any of it.

An extract would be:

kernel: Intrusion -> IN=pppoa0 OUT= MAC= SRC=93.155.198.6 DST=94.4.43.6 LEN=48 TOS=0x00 PREC=0x00 TTL=113 ID=4127 DF PROTO=TCP SPT=2707 DPT=445 WINDOW=65535 RES=0x00 SYN URGP=0

I assumed these were just random pings from around the internet.

Update 3:Yup WMM is enabled and yes, it is AES only.

 

I suspect this is an issue with your ISP. To eliminate the wireless issue (if any), try connecting wired to your router and check things out. Those logs from your router looks like blocked intrusion attempts, but 99% of the routers in the world will have similar intrusion attempts anyway. Those are not pings because of the port numbers. They are all registered ports that certain application need to communicate with remote system over the Internet. I looked up 1430, and it looks like it's used by a company that makes Point of Sale software.

I would contact your ISP. If it's DSL, you may have issues with the physical telephone line causing intermittent drops and poor signal quality. I don't think this has anything to do with your PC or your wireless. Good luck.

EDIT: Sorry, I reread your post and realized that you stated you didn't have issues with the other machines. I guess just trying the Ethernet port may be your best bet.

 

Hey there,

Indeed, ethernet offers no problems. I have since switched to a crappy D-Link router that I have and I get zero problems now. Half win, half fail.

I now have a rather expensive router that I can;t use with my expensive computer. Why is this always the way of the world???

There's obviously some conflict with the WNDR3300 and the 6300, but I have no clue what that could be.

It also means that my xbox which is (was) connected to the network through a, again, expensive 5ghz only bridge, is now redundant. I will have to buy a new decent router and a new bridge for my xbox if I want to have no problems with one single laptop.

Oh so annoying. I wonder if anyone could hazard a guess as to what the conflict could be.

 

I assume you had already fiddled with settings on WNDR3300 and it hasn't helped. Check if your firmware is the most recent one.
Also keep in mind that NWDR3300 is supported by DD-WRT which may solve your problem.
