thanks VB..

my speeds still arent at the advertisted 6mb/s, but increased from 3.2 to 4.2 on nitro, 2.9 to 4.1 on speakeasy.

not bad, considering my adapter is not very good!

Thanks

Hi - I had comcast 3/down, and recently upgraded to 6/down (and got their cable- they are coming any minute to install the tv service). However, my line speed has really not increased, and i'm wondering if there is anything i can do to increase it. This is the result from the line test on my connection - wireless pci adapter - I had to use the flat test. [[Results

I pay for comcast 6down, and know the wireless pci causes significant loss in speed (especially since it is AT&T pci adapter, total trash) albeit my hardwired computer, (I unplugged the router and conected directly to the modem) will not exceed ~4.2mpbs. I have a modem that is probably 2 years old, branded comcast (WebSTAR DPC2100) and am wondering if the speed lost is from my end, due to the modem not being capable of these speeds, or if it is due to the actual line itself. I'm thinking about upgrading to the Surfboard SB5120, and wondering if there are suggestions?

Interestingly enough, I've run the NDT test thru nitro.ucsc.edu to check for duplex mismatches, but everything seems to check out ok - and my speeds appear much higher there on my pci adapter. I'll post up my results here. Note that all values are for the wireless computer (802.11b/g AT&T PCI adapter!) 

------  Web100 Detailed Analysis  ------

Cable modem/DSL/T1 link found.

Link set to Full Duplex mode

No network congestion discovered.

Good network cable(s) found

Normal duplex operation found.

Web100 reports the Round trip time = 38.77 msec; the Packet size = 1452 Bytes; and

No packet loss - but packets arrived out-of-order 0.13% of the time

This connection is receiver limited 97.94% of the time.

This connection is network limited 2.03% of the time.

Web100 reports TCP negotiated the optional Performance Settings to:

RFC 2018 Selective Acknowledgment: ON

RFC 896 Nagle Algorithm: ON

RFC 3168 Explicit Congestion Notification: OFF

RFC 1323 Time Stamping: OFF

RFC 1323 Window Scaling: OFF

Information: Network Middlebox is modifying MSS variable

Server IP addresses are preserved End-to-End

Information: Network Address Translation (NAT) box is modifying the Client's IP address

Server says [69.xx.xx.xx] but Client says [192.168.1.100]

estimate = 285.74 based on packet size = 11Kbits, RTT = 38.77msec, and loss = 1.0E-6

The theoretical network limit is 285.74 Mbps

The NDT server has a 101.0 KByte buffer which limits the throughput to 20.35 Mbps

Your PC/Workstation has a 17.0 KByte buffer which limits the throughput to 3.42 Mbps

The network based flow control limits the throughput to 3.71 Mbps

Thanks!
