Two G75's with the same Atheros-AR8151 major UPLOAD SPEED problem? Qualcomm V2.1.0.12

[g75owner]

I have the G75VW-DS73-3D. Has anyone seen this problem please?
The Atheros AR8151 PCI-E Gigabit Ethernet Port has a major UPLOAD SPEED problem!

The upload speed is capped at a mere 0.1 MB /SEC, it should 100 times faster 10 MB / Sec!!! Note 1, the download speed is perfect! Note 2, the Wi-Fi upload & download speeds are perfect! Note 3, its not a unique fault with my G75 as a 2nd working G75 has same problem! Slow uploads are apparent when uploading data to the network, such as running an UPLOAD INTERNET SPEED-TEST, or COPYING A FILE to the network. Its also apparent copying files to a NAS storage driver or a 2nd directly connected PC. Because of Note 3 I want Asus to replicate this problem and troubleshoot it. I don't want to RMA!

Here's what I've tried.

#1. Updated Driver but Asus site only had V2.0.8.8. Found post with Qualcomm V2.1.0.12. Same problem!
#2. Used several new LAN cables. Same problem. Slow Upload! 0.1 MB / sec
#3. Virus checked the G75. No viruses found! Slow Upload! 0.1 MB / sec
#4. Turned off the virus-checker / firewall. No difference! Slow Upload! 0.1 MB / sec
#5. Selected high-performance Power mode. Still Slow Upload! 0.1 MB / sec
#6. Tested using a 2nd identical working G75. Same slow upload problem! 0.1 MB / sec
#7. Tested network using a HP laptop running Windows 7. Its fast! Upload speed: 10 MB / sec
#8. Tested network using an Asus EEEPC running XP. Its fast! Upload speed: 10 Mb / Sec!
#9. Tested using a NAS storage drive directly connected to the G75. Slow Upload: 0.1 MB / sec.
#10. Tested connecting the G75 directly to 2nd G75 or the HP. Slow Upload! 0.1 MB / sec
#11. Ran a G75 Wi-Fi versus Ethernet cable test. Wi-fi copies at 2-3 MB / Sec as expected.
#12. Substituted the Router a UBEE, for a Cisco. Same slow upload problem: 0.1 MB / sec
#13. Tried changing TCP Tuning Settings. Same slow upload problem! 0.1 MB / sec
#14. Altered Atheros Device Manager settings i.e. Speed and Duplex. No difference! 0.1 MB / sec.
#15. Searched internet for known Atheros Upload speed problems. Nothing found that fixes the problem!

Agree John its looking that way. I had read posts before posting on ROG that claimed changing the Speed and Duplex settings in the same Device Manager -> Atheros -> Properties box fixed it for them. I also read about people running a command line TCP Tuning request which also fixed it for others. This also makes me wonder too what else is being affected?! Tricky problem to solve, and it should have been easy really...

sorry what i meant was mine works out of box, default settings (for my machine by default they are Large Send Offload v2 (IPv4) enabled, Large Send Offload (IPv4) enabled; no issue).

yeah i think it's like what john pointed out. i always thought these hardware, its drivers and settings should have standards to follow (it's a plug-and-play world; at least it has a auto-switching mechanism/profiles to play with), but apparently still not possible to all of them lol!

Interesting. So one theory could be, at the time of building, they had a patch to run after the imaging was complete that a badly trained probably outsourced tech forgot about on batches of G75 machines from April 2012..... Perhaps the same untalented uninterested tech that works at Asus VIP support...

You know I wrote 50+ emails over 3 months to the bullsh*t VIP Asus support. That 50 includes replies and creating new repeat cases in the hope of getting someone knowledgeable. Not a thing! Week after week a single reply would come:

‘swap the LAN cable’ "for a try",
‘get a new virus checker’ "for a try",
‘try a new router’ "for a try"

.... You get the picture. They like that phrase "for a try". Actually it sums up their amateur have-a-go attitude to troubleshooting. They never ever try to replicate problems, they just read from a script and refuse to escalate anything to 2nd tier support! Invariably cases end with ‘go get an RMA’ which wasn’t possible- see below..

Whereas you talented guys on ROG solved this problem in one or days! Its difficult to comprehend how a $2000 laptop can have such sh*tty outsourced support…. And don’t get me started on the irony of using the term VIP!!

I’m unlikely to buy Asus again, which is a pity as I loved their netbooks and got many for friends and family. Their EEEPC’s were so simple to use, had limited bloatware but had tough construction. I took one all over the world travelling for 3 years. I just shoved it into a packed backpack. And while the screen now goes red or blue when I move the hinges, the damn thing still works. I'm typing on it right now and It rarely ever crashes, and when it does its probably a memory leak in XP!

Whereas my G75 would crash once or twice a day in a fatal freeze that was impossible to trace but likely to be a faulty GPU / Motherboard / Memory issue or a critical patch like the Atheros one, that wasn’t executed during the build! But I was stuck with the G75 because the supposed 2 year international warranty is only as international as Mexico, Canada and the US. And I thought congress had poor awareness of foreign relations!

@g75owner, you're welcome. good to know that you have great speed now 🙂 yes, your case is a rare one; so far i haven't found another similar one in the forum.

if your system is still experiencing problems, have you tried run 'sfc /scannow' in elevated command prompt? the next two options might be doing recovery or clean install. a g75 shouldn't act that way.

[g75owner]

Yes had tried sfc /scannow run as admin as I'd seen it suggested on another forum. No joy I'm afraid. After 6 months of troubleshooting, I'm sure the hangs are due to a buggy Nvidia 670m. So a bad batch of G75's is at work here I suspect. Asus have been all too silent on this though. But I now suspect they sent me a refurbished G75 as a replacement, one with the same problem albeit less severe. Now that I have a 2nd G75 to play with I'll be trying the latter two options you suggest. Cheers Rewben!

[rewben]

six months for trouble shooting?! now i really think you're one of the most patient persons in this forum.

and good luck to you 😕

My own problems were solved by downloading the drivers from here, rather than from Asus or Atheros:

@Speranza, you wouldn't happen to be able to share the drivers you downloaded, would you? Qualcomm has changed their site, and I can't find where to download any drivers at all.

This problem has resurfaced for me. I was on another thread about this issue, and it was solved for me. Now, for some unknown reason, I keep getting pathetic upload speeds. I have to go through the whole advanced settings changes, reboot, try again cycle a few time a day. It's incredibly frustrating.

Thanks!
