can someone help me tweak my pc please. I have just bought a new router and am experiencing very low speeds. My download speeds are lower than my upload speeds. Using the current settings, i get download = 216kbps upload = 241.60kbps. This isn't normal for a 1Mb connection I've done a speed test on my laptop [via wireless and on same router] and i get normal speeds. I just get rubbish speeds on this pc via ethernet and on same router.
PPPOA [i think. My isp tells me to configure my router as PPPOA. but i connect through the internet via a router and pc is hooked upto it via an ethernet cable. So i'm not sure]
ISP and ADVERTISED SPEED
ISP is Pipex [uk isp] and i'm on a 1Mb/256Kb connection. Not sure what that means in kbps.
I've used command prompt to ping a site and have found that my max mtu is 1492 as this is the highest number i can use without the ping telling me of fragmented packets.
TCP options string = 020405ac0103030301010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.
Default TCP Receive Window (RWIN) = 511104
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled TCP Receive Window = 63888
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8) <-- current value
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 20444.16 kbps (2555.52 KBytes/s) @ 200ms
Your TCP Window limits you to: 8177.664 kbps (1022.208 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 59 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
