Need Help With Tweaking!!!!

[Hadear]

I had just bought a Gigabit Switch and i need help tweaking.
My Cable Modem is hooked up to a Linksys Router...The Router is hooked up to the Gigabit Switch and the Switch is hooked up to my Desktop. Im getting Gigabit speed.

I have Road Runner..... Up to 7-10 Mbps downloads

I tried a few games to download for like 20 sec. and i got no more then about 60kb/s download.
I know i can get way better then that.

Thanks you.

"Other network traffic" means something in your comp is causing background traffic during the testing. Scan for possible spyware/malware.

Round trip time in the US is usually 90-130ms, and yours is a little high. Your latency to Toronto is very high at 846ms.

What kind of firewall and antivirus are you using?

[Hadear]

Im using the integrated Windows Firewall...and im using the PC-Cillin Internet Security 2007...

I'll check for Spyware and stuff and tommorrow i'll tell whats going on.

If your PC-Cillin has a built-in firewall, turn off Windows Firewall.

[Hadear]

Yeah it does....i turned of my Windows Firewall..you want me to post another check and stuff?

Post it tomorrow after your scan for spyware.

What brand and model is your modem?

[Hadear]

Well my Modem is Motorola SurfBoard which is hooked up to the Wireless Router (Linksys WRT54G v.5) the Router is hooked up to my Gigabit Switch (Netgear) The Switch is hooked up to my Desktop to a Roswill Gigabit NIC card.

Turn off your router and connect your comp directly to the modem by cable and test your speed. This is to eliminate any cause for slow speed at the Nic or router.

[Hadear]

I tried both NIC...the integrated one and one i bought...When i connected it directly to the modem it said Limited or no connectivity for both NIC cards.

[trogers]

I am not familiar with this brand of modem but here is a link to the user guide and assistance to troubleshoot the modem:

http://broadband.motorola.com/consumers ... _Guide.pdf

[Hadear]

Everything it said was already done to my cable modem.


Even though im not directly connected to the router but to the switch...You think other people besides my Sisters Laptop and my nintendo wii are limiting my network.,My sisters laptop and the Nintendo wii are the only Mac Addressed i allowed to use my wireless internet. Or is it a Cable Modem problem.

Or is it a Cable Modem problem.

The nitro test did report "other network traffic' limiting your speed. If you are testing your comp while some other comp or device is also using the internet line, the total bandwidth will be shared among the connected devices.

For this reason, I proposed to connect your comp directly to the modem so that it is the only device using the line and be able to find out if it can achieve optimum speed, thus eliminating factors from router, switch and other devices.

[Hadear]

When i connected my comp. Directly to the Modem..it said Limited or no Connectivity.


Sorry for all this.

Sorry for all this.

How about connecting your modem to the NetGear Switch, bypassing the router?

[Hadear]

I can try that...but i just found a whole bunch of infections on my comp. so i'll get back to in like an hour or something..


Thanks.

When i bypassed my Router and used the switch and cable modem. it still said Limited or no Connectivity.

I got rid of all the Spyware and Virus i found. And one time it said that my connection was limited 6%. I did it again and it went back up to 99%.

This is really what im getting when i download something.

Let's try bypassing the switch by connecting your comp to the router using a cable. Do some speedtests and a tracert.

Maybe my cable modem is going bad.

Check the log of your cable modem with this thread:

I cleared the Log this morning. But it had a lot of Failure stuff in it.

I can post some of the stuff as soon as the log starts to fill up

I do not see any problem with power levels and SNR in your cable log.

Check your cable lines and splitter that connects to the cable modem for possible bad connection. Are you staying in a house or condo?

[Hadear]

House....All my cables are snug in and tight. I just got new cables the other day.

[trogers]

Are there any other electrical devices placed near to your modem? Any cordless phone nearby?

[Hadear]

I have my Modem, next to it is a Stack of Blank CDs and DVDs then next to that is the Switch, and next to the Switch is the Router. all on a shelf. And right under the shelf beneath the modem is my tower....thats about everything that close to it. or within 5ft.

I am trying to think for a possible cause for this in your nitro report:

"There were 43 packets retransmitted, 176 duplicate acks received, and 143 SACK blocks received"

These are usually associated with lost or damaged data packets. If your cables are new, what about your splitter?

Sorry for this stupid question. its really the only thing i dont know..whats a splitter?

[trogers]

That's the little box that splits the cable into 2 lines: one to your TV and the other to your cable modem.
