Ethernet Disconnects Randomly Especially While Gaming

[infamouslyle]

Hi guys, I just got a new ROG 56JR . It's running on Windows 8.1 and has a ethernet driver of Realtek pcie gbe family controller.

Of course, I bought this laptop for gaming purposes.
I connect the laptop through both wire and wireless connections. I have a 200Mbps data worth. ( For your information )

However, problems come up in-game. (Game I am playing is : League of Legends)

Once into the game, I would experience a 9-11 ping, however , on random times , the Ethernet(wired connection) will cut of by itself and reattempt to connect which it does connect after a few seconds.

This affects my experience in game, as I will concurrently receive a "spike"(moment where i disconnect for a short moment) as
this Ethernet disconnection occurs. I can continue playing the game after the ethernet reconnects, however experiencing such spikes in game randomly is affecting my game play.

Ethernet Cable tried : ( Cat 6 and Cat 5e Wires )

*I updated the drivers to the latest version but it doesn't seem to help.

This only happens in League? Or other games? Try something else for a while, it could be router related..

What is your router?

What is your Wireless Card? (E.G. Atheros, Killer )

Can you recall any other time your connection has dropped?

How far are you normally from the Router?

Have you stolen any cookies from the cookie jar?

Is power saving mode currently active on the Card?

This only happens in league and not other games.

I am using a A5520N Pace Router.

My wireless card is Intel Dual Band Wireless-N 7260

Basically, it's just during in game there will be disconnections and spikes. So far , browsing of net and streaming of videos is good.

For wire, it doesn't matter. But I am currently using a CAT6 wire that is 15-16 metres long so that i can connect it to the router(modemn).
For wireless, My laptop is on a study table approximately 6 metres away from the router(it's quite close).

Cookies?

I unticked the check box after going through some forums threads mentioning it, but it doesn't seem to help. 🙂

*Update: Wire(ethernet) connections still causes spikes in game, when spikes occur, the connection seems to be limited and shows identifying before connecting to the ethernet again.

Wireless : Wireless works fine, but there will be ping spikes randomly throughout the game.

Ping spikes while gaming aren't unusual due to response from the server and vagaries of the path in between. More aggressive settings for IP/TCP can help, check out this tool and the forums there for tuning. Your download speed is more than enough, and your upload speed is likely the same. Use TCP Optinzer to change your default network tuning settings to settings that take advantage of your higher speed than normal connection - that may be all you need to do to get rid of the ping spikes.

And, I am not familiar with your router, but if it has any tuning for gaming, you can try that on/off to see if that helps.

But the ethernet losing sync with the router is bad, and usually indicates a physical connection problem. If you are getting into the game and pushing around the laptop, you could be wiggling the wire plugged in to the G750.

If you have already tried a few cables, it might be the socket in the G750 is flaky. That would suck - but you need to know - so try gently wiggling the cable / plugged in side while you watch the network systray indicator and see if you loose sync again.

If that is solid, it sounds like it might be the router. Bypass the router and try connecting directly into the service modem ethernet, power off/on the device/G750 so the new MAC address is allowed, and try gaming that way. If you don't lose sync, then it is the router.

If you are building your own cables, try a molded connector commercial cable that you can be sure about the connections. I have seen ethernet crimpers go weak and not punch good connector/wire connections. And, you might not be bearing down hard enough to punch through the cable insulation solidly enough and you are getting intermittent connections that flake out under physical vibration / strain.

Let us know what you find out 🙂

I guess it's just normal lag in your vicinity. Try modify your TCP outlets from pairs to single packages, it'll close to half your latency for all online gaming on that particular machine. You can do it via the registry manually or use a program hmscott has provided.

I myself just use this.

http://www.wowinterface.com/downloads/getfile.php?id=13581&aid=67761

Download, unzip, open, install.

1,2,3,4 quick and simple, go game more.

You can uninstall the mod any time you wish, too. I myself wouldn't be caught dead without it though. 70-90% latency reduction is great.

It would be nice to see them expose the actual settings they change, there are only so many described / considered by Windows - the values aren't a mystery, so why don't they tell us what they are doing, exactly?

Or am I missing the listing of the settings / values changed?

Thanks, hmscott. :3

Humm, there's another version (3), the latter uses python and I believe it's all open so you can check it. I linked the previous which is 2. It does the same thing, but you need to reboot the system or turn off and back on your wireless. I use 2 since it's smaller, and doesn't seem to uninstall itself as often.

It most likely changes things in here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces
And other locations to fetch your local IP and so on.

I usually keep this program to myself, because it's what gives me the edge over others. >;p Shh shh don't tell anyone.

Also just if you were curious, version 3 lets you use it without having to have .Net Framework

Thanks for sharing Darnassus, but the edge is you, not the settings 🙂

I will check out the open version to see what they are setting!

I checked, but the Version 3 comes with .pyd files, not source files. I found the latest forum support for Leatrix said that the vbs scripts were readable, but there are no vbs scripts in either version 🙂

I did find a description by someone here as to what leatrix patch is setting:

http://www.elitepvpers.com/forum/aion-hacks-bots-cheats-exploits/1882780-leatrix-latency-fix-2.html#...

And, it is the same as the Advanced Tab settings for Gaming in TCP Optimizer.

I guess I could set to defaults, run the Leatrix patch, and check what TCP Optimizer finds changed from defaults...

For now I will stick with TCP Optimizer 🙂

If someone has the source, and/or knows all the settings Leatrix is setting, please let us know!

[hmscott]

Here are some notes on how to use TCP Optimizer, as I use it anyway, and I encourage you to read the docs at the links above too 🙂

To use TCP Optimizer, download and right click to start as Administrator - you are changing system settings so you need to have Administrator privileges

Select the network adapter you use most / now in the adapter drop down. Then Click "Modify All Network Adapters".

Click the Optimal settings Radio button below, and drag the Connection Speed Slider to match your download speed - that slider setting is used to compute a number of Optimal settings - I usually bump it up a bit past my actual speed - it seems to help a bit - I have 57mbps measured, but set the slider to 65mbps.



Now, click on the Advanced tab, Click on the Custom Radio button, and set the Gaming Tweaks as shown, 1/1/0



Now you are ready to Click Apply - and you will see all the settings being changed, their old values, default values, and new values - along with their path in the Windows Registry. You might want to expand that dialog, and use the Windows Snipping Tool to take a screen shot of that dialog so you can read up on the values changed.

Then you will be asked to reboot, most changes require a reboot to take effect.

You should have better throughput, and less lag 🙂
