Hi!

 

I looked for solution to my problem, but couldn't find anything. So i thought maybe you guys could help me out.

 

I recently moved in to a new apartment and set up internet via cable. My internet connection is fine until another computer comes online. From that moment on internet will have massive lag spikes. We are both gamers. The lag will stop the game from working for us both simultaneously and our phones wifi( so the whole internet goes dark). But skype conversations will still work and i can still connect to youtube etc.

I've called ISP, who said that he cant see the issue from their side and ive tried updating both computers also ran a virus scan for both.

 

Here are the detail

 

PC1

Wired

Router is Thomson TG789vn 

-

DSL

 

PC2(Vaio SVP132A1CM)

Wireless

Same router

aprox 70cm

DSL

 

Ive attached the MiniToolBox log's aswell

Do a speedtest.net bandwidth test with one computer on and then another with both then post both results for review

There isn't that much difference between the two in terms of data speeds. The fact that they are on different network segments -- one connected via Ethernet, the other via WiFi -- would seem to indicate the problem is with the router's connection to the internet.

 

I'm not familiar with that router. Can you check to see which DNS servers it is using for the Internet? Can you change those settings to point to something like OpenDNS's servers? I suspect you are using your ISP's default DNS servers.

 

Also, since you are both gaming, is it possible your ISP is throttling your data?

I would like to see speed tests done when one pc is gaming and when both are gaming. It would indicate bandwidth usage/limitations

This was made at the same time we had this massive lag spike. Both were gaming.

 

Also i changed the dns servers to OpenDNS with telnet, but ISP "forced"( dont know if its the right wording) its dns servers there too. So atm there are 4 dns servers 1st and 2nd are OpenDNS ones. In the thomson web it displays the opendns dns servers as the ones its using. And i do not know about my ISP throttling my data, if it does, it should happen while torrenting also, but i can download torrents freely. 

 

Sidenote: the problem arises only when the 2nd computer is gaming. The problem comes even if its the only computer gaming.

I have tried:

Changing DNS servers

Flushing DNS

Restarding router

Updated all drivers with Io Driver booster

Updated all game components

Updated windows( with windows update fixer) + changed windows downloading peer2peer settings

Ran malware scans with Malwarebytes

Spoken with ISP, they said that they cant see the problem from their side

 

Can i provide more information or is there something else to try?

Sounds like the Vaio is the culprit here. Try connecting it using Ethernet, with the WiFi off, and see what the performance is like.

 

You might also want to review the WiFi settings on that computer.

I went and got another router. With this one all works fine, BUT i gotta pay every month for it.

If someone knows how to "fix" the old router, any info would be nice.

I'll have to amend my earlier assessment. It wasn't the Vaio. It was the WiFI radio on the old router. Hard to tell if that is a hardware issue, or a WiFi settings issue, without seeing the actual config on the router.

Sorry for the delay. Been busy.

 

Yes, a screenshot of the WiFi configuration on the router would be helpful.

No problem, same here.
I connected the old router back and did some firmware update that i found on the internet( ISP had not said anything about it). After that wifi settings changed a bit and have not had problem since. Gonna give it a litte more time to test, but it probably was what you suggested.

Yep. Old router was using some old 802.1x config that didn't match with what was on the computer. Firmware update would have fixed that,

 

If the ISP gave you that router, you might want to check with them to make sure the router gets firmware updates automatically.
