Ukonline 2mb connection


Recommended Posts

Hey all!

Changed my ISP to Ukonline a while ago, and all was fine for a while. It's a 2000/256 connection. However, after a major issue my motherboard had with my new RAM (a Corsair 512MB PC3200 chip) and a bad XP crash I had to re-install from a formatted HDD. Now everything is back up and running I'm having trouble...

TCP properties for IP = ()

Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1

Notes: Read the Analyzer 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 TCP Receive Window (RWIN) = 63888

RWIN Scaling (RFC1323) = 0 bits

Unscaled TCP Receive Window = 63888

For optimum performance, consider changing RWIN to 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 (Note this is not a speed test):

Your TCP Window limits you to: 2555.52 Kbps (319.44 KBytes/s) @ 200ms

Your TCP Window limits you to: 1022.208 Kbps (127.776 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 56 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 11110000 (240)

Precedence (priority) = 111 (Network Control)

Delay = 1 (low delay)

Throughput = 0 (normal throughput)

Reliability = 0 (normal reliability)

Cost = 0 (normal cost)

Check bit = 0 (correct, 8th checking bit must be zero)

DiffServ (RFC 2474) = No valid DiffServ equivalent. See the TCP Optimizer documentation, or RFCs 2474, 2475, 2597, 2598, 2873.

Yes, I'm connected up via USB, but I've always run a steady stable connection, so that shouldn't be a problem. I've tried using VanBuren's new Cablenut settings, got a couple of extra kB/s, but nothing of note (last time I used a VanBuren setting my speed increased over 20%!). I'm using an up to date XP Proffesional, and the system is a Compaq Presario 2.66GHz Pentium 4, 512MB RAM (it was a GB until the crash...), 400GB drive space spread over 1 40GB, 1 60 GB and a 1 300GB HDD.

Thanks in advance for any help offered!

Hey all!

Appreciate all the help I'm getting, but I still have a problem...I applied the 2000/256 Cablenut settings, and I've run some speed tests from that link:

Just got off the phone with Ukonline, they got me to run the line providers test (British Telecom) which came up with the same (slow) results. Despite me paying for a half hour phone call something has at least been looked at, but it's now in BT's hands as it's their hardware and not UKonline's.

If anyone in the UK is using a Broadband connection that runs through a BT line, these login details will get you to their line speed tester if it's any use:

Username: [email protected]_domain

Password: dsl

URL: http://speedtester.bt.com

If however anyone still has suggestions for my connection (as it may not be BT's fault) they will be appreciated!

Cheers Trogers!

Your Round trip time = 797.23 msec. Usually RTT < 300 ms from computers of overseas users.

High round trip time usually points to poor line quality or electromagnetic interference on your signal cables or modem/router. Make sure modem and router are place a few feet apart. Check to see ensure other electrical devices are not placed near to them (eg. subwoofer, speakers, cordless phone, fax...etc). If using wireless, interference in signal transmission to router can be a possibility.
