Slow connection, packet losses problems !!!

[bl1nd]

Well i have a cable connection speed are supposed to be 1024/128

My story goes like this i always had a perfect connection until i recently bought a new computer installed vista... NIC is an intel gigabit integrated in my motherboard
I uninstalled vista thinking that was causing problems WRONG... installed XP still my connection remains crap..
My connection download speeds are very unstable sometimes i dont even pass 20kb/s :S
Im having packet loss problems when i play games online even having a good ping like 85ms i still lag a lot...

High and irregular ping times at your modem in hop 1. Either your modem needs an updated firmware or it is being affected by electromagnetic interference from some nearby electrical devices.

Downstream Value
Power Level 12 dBmV

Downstream power level is too high at 12 dBmV. Ideal is a value of zero. Normal working should be + or - 3 dBmV.

After checking for the latest firmware and relocating your modem a few feet away from all other electrical device, turn power to your modem off for 10 mins before rebooting it.

Then check your power signals again to see if you get an improvement. If not, you will need to call your ISP tech in to check your line and set your power levels.

[bl1nd]

Yeah i noticed that about the first hop... i rellocated my modem and power level went down 1... lol

Firmware upgrade u think i can do that without screwing my connection on a motorola sb5100?

Usually, your ISP will upgrade the firmware of your modem automatically through the connection line. This is one of the purpose of powering down your modem and rebooting.

[trogers]

When ping times of your modem are lowered and regular (est. at <10ms), try the following with TCP Optimizer:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64
TCP Receive Window - 32120
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
Timestamps - uncheck

Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0

ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

okay so i powered down my modem for 10 mins and now my tracert changed

Ping times at hop 1 are better though not ideal (eg. 9 ms for all). Both tracerts show an '*' in one of the ping times at hop 2. Check to see if you have any loose connections or wiring between modem and wall socket.

When you lower your RWIN to 32120, does your test shows the following?

Your PC/Workstation has a 31.0 KByte buffer which limits the throughput to 1.05 Mbps
The network based flow control limits the throughput to 0.58 Mbps

The 'network based flow control' means the network of your ISP. If this limits your throughput to lower than 1.05 mbps, it means high traffic in your ISP's network is slowing everyone down and you will not be able to achieve 90% of your subscribed speed even though you have adjusted your PC buffer to achieve the necessary throughput.

[bl1nd]

The theoretical network limit is 0.27 Mbps
The NDT server has a 105.0 KByte buffer which limits the throughput to 4.41 Mbps
Your PC/Workstation has a 31.0 KByte buffer which limits the throughput to 1.31 Mbps
The network based flow control limits the throughput to 0.47 Mbps

SO i have no solution i think im going to change to DSL...

[bl1nd]

i keep getting high ping in the first hop... i just did a tracert and got 71ms in one hope what can i do to solve that?

[Sava700]

run pingplotter from www.pingplotter.com and let it hit a few locations for a while then call them when you see that one certain hop always shows packetloss.. they can't ignore the facts

[bl1nd]

But what about first hop thats the thing that worries me... maybe the cables in my house are bad or the modem is bad

[trogers]

But what about first hop thats the thing that worries me... maybe the cables in my house are bad or the modem is bad

Checks on power levels and making sure the modem is not placed near to other electrical devices will give you a degree of assurance that the modem is not bad.

Another possible cause for spikes in ping times is the presence of spyware/malware.

Have you go into Windows 'Safe Mode' to scan and remove spyware/malware? If not, search Google for SpyBot and Lavasoft Ad-Aware, download and update them to scan your comp.

[bl1nd]

Well i made a call to my ISP i explained everything and still they say everything seems to be ok and that they cant send a tech because everything looks regular...

I dont know what the heck i can do about this it doesnt matter the hour i download 11kb/s

Let me try that last thing i have ran a thousand tests for spyware

done nothing my pc is clear still my connection is utter crap :S well im just screwed... i guess the only solution is change ISP to DSL....

Can u believe they refused to send me a technician? and the guy had no solution for my problems... in a few words they told me i should cancel the service or live with it

and told them about the first hop high pings and if they can change my modem because i think there is a problem with it and they said no we cant change it, it looks normal

My fault for living in a goddamn third world country
