Internet dropping

[Guest beccie]

Right, brand new laptop, been working fine for the past 10 days, until last night. Logged onto 3dx, plagued by constant disconnections which I realised pretty quickly was the result of my WiFi dropping for a few seconds at a time.

 

Internet appears to operate normally the rest of the time - just not when 3dx is running (tried this morning to test it, same problem). All other devices running normally on WiFi. WiFi on my laptop displaying as full strength, just not when 3dx is running. 3dx running fine on my PC with ethernet cable, so no problem with my router.

 

Plugged the ethernet into my laptop, no problems.

 

Not convinced that 3dx can interfere with WiFi!

 

Have changed the power management settings and also disabled the power saving to the WiFi adaptor - still same problem!

 

Haven't tried a full reinstall yet cos i cant see how that would help.

 

Any ideas?

Mmh 3DXChat is extremely sensitive and disconnects from slightest interruptions x.x In the first place I think this is something the developers should fix..

 

Anyway after a little googling I found this: 

 

I work for a major broadband provider and in most cases it is not the loss of internet to the modem or modem to router. I wrote this up to give to my fellow techs, feel free to use and pass on. 

 

If you are experiencing constant Wi-Fi drop outs this is most likely do to Wi-Fi interference. (Caused by the oversaturation of the 2.4 GHz and 5 GHz frequencies by devices like cordless phones, wireless alarm system & devices, and any and all wireless devices found in common household these days) and not caused by the modem losing the internet connection. Note; resetting the modem and router is just a temporary fix to the problem you are experiencing by forcing the router to restart and lock on a new channel but then the “auto channel” feature kicks in and changed back to a noisy channel and you are kicked off again.
(And this is also considering the devices losing connection has the latest device drivers or OS and the router also has the current firmware available by the manufacture)
I would suggest doing one or both of the following to fix the issue. 

A. Set Your Router to a Specific Channel
Here’s a tip that can get your wireless connection from dropping out repeatedly. If you are using a router (particularly a dual band router) you’ll want to go into the wireless settings and specify a channel. Try using a different channel other than the default, and make this settings for both of your bands (2.4Ghz and 5Ghz) if you’re using a dual bound router. Definitely do not use the “auto” setting. From our troubleshooting it appears that this is the main culprit. Try setting a higher channel, and if that doesn’t work, try different channels. It’s very possible that there are enough networks in your immediate area on the same channel that they’re conflicting with each other.

B. Adjust your wireless router settings
1. By lower the MTU (Maximum Transmission Unit) from 1500 to 1492 or less (usually found on your router’s main/ basic setup page)
2. Adjust the following advanced wireless settings:
3. Lower the beacon interval from 100 to 50
4. Lower the fragmentation threshold from 2346 to 2306
5. Lower the RTS threshold from 2347 to 2304

 

Also the problem might not be a Wi-Fi issue but a computer issue.

Laptop and power saving mode issues

Dead connection when laptops are on battery and switch power saving modes. For Wi-Fi - most Windows laptops default to "maximum performance" when plugged in and then shift to "moderate power savings" when on battery (you'll find these settings in Windows under Power Options > Change Plan Settings > Change Advanced Power Settings > Wireless Adapter Settings > Power Saving Mode). On some laptops - the Wi-Fi connection would go "dead" when undocked/unplugged, but would resume when plugged back in. 
Or when a laptop goes into sleep mode and the network card does not wake up when the laptop does. 

The workaround is to set the card for "maximum performance" while on battery

 

 

Also this:

 

 

Here is how I fixed it. It has not happened since. 

(fyi I use windows 7) Go to your control panel. Select Device manager. Then Network adaptors. Choose your wifi link (probably Intel 5100 AGN) and choose adhoc Qos mode and enable the WMM........

I have windows 8.1 here is how I did it

in search box search for device manager
click device manager then look for network adapers

click network adapters then find your wifi adapter in the drop list (should have a name)

then right click on the correct wifi adapter 

select properties
then click advanced tab

and change it to AdHoc mode click ok close all windows and u should be right to go

 

Aand some people saying simple malware and virus scan did the trick x)

Thx rochi for your ideas.

 

I've already set the router to the best channel and disabled the auto power off to the wireless adaptor.

 

Strangely after I plugged in the Ethernet to the laptop and then reverted to WiFi afterwards, the problem seemed to stop... I'll log back on tonight when the network is busier to see if there's still the same improvement.

Hello,

 

3DX is not so sensitive to disconnections.. I have tested it myself and it needs about 3 seconds of complete packet loss before it realizes that the internet is gone and disconnects you. If the connection comes back (and you still have the same IP) the game resumes normally.

 

In your case I would leave a ping open to an internet IP (let's say 8.8.8.8) and one ping to your router IP and monitor packet loss to both of them to understand if it's an internet problem or a lan problem. Just leave those two ping windows running while playing and not playing 3DX and see what happens.

(start -> run -> cmd and in the cmd window -> ping -t 8.8.8.8)

 

If you see deviation in the latency in your router's ping, then you probably have some weird problem with your lan.

If you only see increased latency or packet loss to the internet IP, then your lan is fine but something is downloading/uploading too much and causes your internet connection to become very slow.

 

PS: do those tests once with the laptop running on battery and once with the power cord connected.
