Yeah Ive been getting packet loss and general lagginess at a normally excellent 50 ping at my favourite server...how do i fix this!

SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = ZZZZZZZZZZZZZ(ZZZZZZZZZZZZZZZZ.net.cable.rogers.com)
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Note: Read the FAQ if the above is not your IP address.

TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 52560
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 52560
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 2102.4 kbps (262.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 840.96 kbps (105.12 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 50 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 01011100
Precedence (priority) = 010 (immediate)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)

A little low dont ya think?

That is quite low for Rogers, try the following Nick:

1. Under your LAN connection - properties - general tab, uninstall all the protocols there except TCP/IP Internet Protocol.

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link).

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with Ad Aware.

YIKES!

Seems like broadband .. above the 1mbit barrier!
