Latency on your first hop is rather high. Here are possible causes: Could be due to a bad line or faulty cable. Old telephone lines may not be suitable to support DSL and needs rewiring. Or electrical interference on signal cables, modem, router. Or if hardware drivers have been recently updated, problem may lie with faulty Nic, router or modem.

Just found and installed this rootkit and intrusion software . Even detected 3 malware in my system and I have to quarantine the 3 infected software. Here are the links: http://www.f-secure.com/blacklight/cure.shtml http://info.prevx.com/downloadremove.asp

This is a good site to scan and clean spyware: http://www.ewido.net/en/onlinescan And here is a good source of security freewares: http://www.techsupportalert.com/best_46_free_utilities.htm

Have you install the patcher to change concurrent Tcp connections from default of 10 to 50? You can install the patcher here: http://www.lvllord.de/?lang=en&url=tools&PHPSESSID=89e182258e07f2e142af1f7e8701287e To speed up FireFox, this thread may be of help: http://www.testmy.net/forum/t-11556 As for Opera, they recently have a new version 8.52. You may also adjust number of concurrent Tcp connections at Tools>Preferences>Network>... The thread on firewalls is : http://www.testmy.net/forum/t-11919

The TCP Analyzer shows your window registry has already been tweaked to optimum settings. Only thing on the software side is to make sure you do not have spywares or similar that may leech off part of the bandwidth. For great suggestions on hardware and cabling, our members in this forum section will be able to help: http://www.testmy.net/forum/b-7

If it is a faulty cable (between your comp and modem or modem to wall socket) you can inspect and change it to a new one. If it is electromagnetic interference, you need only to reposition your modem and signal cables away from other electrical devices. I notice your ISP is providing Cable TV as well. Make sure you do not place the modem on top of your TV set with signal lines running down the back of it. Reposition the modem below the TV so that signal lines can branch out along the wall at floor level.

Your first 2 hops seems to have relative high values. The usual value in the first hop is less than 10 ms and the 2nd about 10-12 ms Check for possible faulty cables or electromagnetic interference from other electrical devices like sound speakers, subwoofer, cordless phone, etc.

This feature in TCP Optimizer is for finding latency. For ease, you can do a reverse traceroute back to your IP Address at this site: http://www.dnsstuff.com/

"Your PC/Workstation has a 124.0 KByte buffer which limits the throughput to 7.06 Mbps. The network based flow control limits the throughput to 0.48 Mbps There were 17 packets retransmitted, 23 duplicate acks received, and 28 SACK blocks received The connection stalled 2 times due to packet loss The connection was idle 0.72 seconds (7.19%) of the time This connection is network limited 99.97% of the time. Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch" Your RWIN setting is appropriate for 5-7 Mbps bandwidth. Seems like the problem lies in signal transmission. Could be due to a bad line or faulty cable or electrical interference on signal cables, modem, router. Or if hardware drivers have been recently updated, problem may lie with faulty Nic, router or modem.

Increasing RWIN is similar to enlarging the signal pipeline. Do a tracert to www.yahoo.com and see if the problem lies with signal transmission.

Do the TCP Analyzer test to see if your RWIN has been changed? https://www.speedguide.net/analyzer.php

Try this ccs file.

Oh...please place a thick book or something similar on the CPU tower before placing the modem on it. The power supply unit of the CPU is usually mounted on the inside top of the tower.

Your welcome anderb. Do read the other posts in our Forum as this is a great place to learn from each other.

Hi Karthic, Here are the conclusions of the tests: Your MTU has now been adjusted to 1480. Since your ISP is giving you a download speed of 256 Kbps, I have made a ccs file for you to suit this speed. You will need to download Cablenut Adjuster program from www.cablenut.com and open the ccs file. Then click 'Save to Registry', exit and reboot your comp to take effect. Your round trip time (RTT) is rather high. This is the time taken for a signal to leave your computer to the website and then back to your computer. If you are in the US, RTT is usually 100-150 ms. When you are overseas, RTT may range from 250-320 ms. Your RTT is 458 ms. Like what FallowEarth have suggested, you may have some electrical interference on your modem or signal cables. Besides your cell phone, other possible source of interference can be router placed next to the modem. They should be a few feet apart. Sound speakers and subwoofer of your comp sound system or a cordless phone set can also emit interference. If no interference is found, then some problem in the hardware like Nic, router or modem may be a possibility. To find out if your ISP network is busy or not, you can do the nitro test and check this part of the result: "Your PC/Workstation has a 63.0 KByte buffer which limits the throughput to 1.09 Mbps. The network based flow control limits the throughput to 1.10 Mbps" When your ISP is busy, the network based flow control limits throughput to ____ Mbps will be smaller then your PC/Workstation _____ Mbps. The smaller the network limit is, the busier is the ISP network. So now you can test to see if your slow speed in the mornings is due to heavy internet traffic.

Hi, In the ping test: ping -f -l (max value) www.testmy.net you are suppose to use numbers 1472, 1471, 1470, ....in the place of max value, example ping -f -l 1472 www.testmy.net Each time a smaller number by one until you get the message: "Reply from XX.XXX.XX.XXX: bytes= ______ time = _____ ms TTL= ___" I think you will get this message at number 1464. If not then at number 1452. Which country are you in? In the nitro test, you will see 2 buttons below the test box: 'Statistics' and 'More Details'. Click the buttons and a new report will appear for each button. Please post the 2 reports.

I also cannot modify setting on my IE to display the nitro test. I can do so with the FireFox Browser. If you want to download and install FireFox, you can go to this link: http://www.mozilla.com/firefox/

Click 'Start', 'Run' and in the box type "cmd" and click 'ok'. In the DOS black screen and after C: use this command ping -f -l (max value) www.testmy.net Where -l is minus small L and max value is your largest anticipated MTU value minus 28. Say you start with assumed MTU value of 1500, max value is 1500-28 = 1472 If you get a message "Packets need to be fragmented..." Then 1500 is not your largest MTU. Go on pinging with a max value less 1 until you get a proper result like "Reply from XX.XXX.XX.XXX: bytes= ______ time = _____ ms TTL= ___ The bytes value shown + 28 = your largest MTU.

Yes you are right that the speedtest result posted exceeded subscribed speed by quite a large percentage. However, this is the point of the request:: "The problem is that speed doesn t remain constant MOREOVER THE TRANSFER RATE too doesn t remain constant inthe sense it varies very widely between morning afternoon ,night .Max speed is attained during afternoon only in the morning speed drops to 95kpbs too!!!!!" Variations in speed could be due simply to internet traffic at different time of the day. But the TCP Analyzer test showed 2 abnormalies: MTU value is a little low (but it may be ISP imposed) and RWIN value high for a 256 Kbps bandwidth. The nitro test may give further clues through readings on signal quality, latency and network imposed throughput limit.

What browesr do you use? Internet Explorer, FireFox, Opera, or some others? We first try to see if we can increase your MTU value to 1500 from 1452. Open TCP Optimizer and do the following: General Settings tab: Custom settings - check Modify All Network Adapters - check network adapter selection - your NIC MTU - 1500 TTL - 64 TCP Receive Window - blank 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 - 5 Host Priority - 6 DNSPriority - 7 NetbtPriority - 8 Lan Browsing speedup - optimized QoS: NonBestEffortLimit - 0 ToS: DisableUserTOSSetting - 0 ToS: DefaultTOSValue - 240 MaxNegativeCacheTtl - 0 NetFailureCacheTime - 0 NegativeSOACache Time - 0 LAN Request Buffer Size - 32768 Then select "Apply Changes" and reboot to take effect After reboot, you can use the feature in TCP Optimizer to locate your largest MTU. Open TCP Optimizer, set MTU to 1500, click 'Largest MTU', then enter any website address and click 'Start'. Your comp will send out pings and establish your system's largest MTU value. If your largest MTU value is more than 1452 we can make a ccs file for you following this value

Here is a ccs file for 600/320 MTU 1480.

Hi, Your speed is 600/320 Kbps or 6000/320 Kbps?

Download the Cablenut Adjuster from www.cablenut.com and open this ccs file. Then 'Save to registry', exit and reboot comp to take effect.

Click 'Start', 'Run' and in pop up, type "cmd" and click 'ok'. In DOS black screen and after C:, type "netstat -a -b" and press 'enter'. Post the results.

Anyway, I have only elementary knowledge with regards to spyware and intrusion programs. You may be able to find good advice in this area at the forum sections on HELP or General Discussion.
