Rank Newbie help needed please

[CrazyKen]

Hi! All
I am in the uk. and a total newbie to broadband, I have just signed up with Virgin (bundle one) my setup came with a Netgear wireless router which I am using as a wireless connection to my two desktop computers, the setup is ok and I am getting speeds of around 2800kbs downloads, Virgin say that I should be able to get speeds up to 8. I know that this is dependent on the quality of the phone line so mabe what I am getting is not bad? I thought that I may try the tcp tweak prog but I do not know if I am PPPoE or not my question, where in the settings can I find this out and any advice on what I may be able to do to get the best from this link up.
Many Thanks.

Post your TCP Analyzer report.

If your MTU is set at 1500, your connection is PPPoA. If it is set to 1492 or lower, it probably is a PPPoE line.

[CrazyKen]

Thanks for the quick reply. My settings:


TCP properties for IP = 82.3.245.243 (82.3.245.243)
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Avant Browser; Avant Browser; .NET CLR 1.1.4322)
Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 0204058a01010402

MTU = 1458
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.

MSS = 1418
Maximum useful data in each packet = 1418, which equals MSS.

Default TCP Receive Window (RWIN) = 17016
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 17016

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
521824 (MSS x 46 * scale factor of 8)
260912 (MSS x 46 * scale factor of 4)
130456 (MSS x 46 * scale factor of 2)
65228 (MSS x 46)

bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 681 kbps (85 KBytes/s) @ 200ms
Your TCP Window limits you to: 272 kbps (34 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 113 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

[trogers]

Log into your NetGear router and note its MTU, MRU and MSS values. Then set MTU and MRU to 1492, and MSS to 1452, save and reboot the router.

Post a new TCP Analyzer report.

[CrazyKen]

Don't forget I am a complete newbie, all I do is switch on and I am conected. How do I log on to my router?

[trogers]

Click this: http://192.168.0.1

Enter for username = admin and for password = password

You can go to this link to download the user manual for the model of your router:

http://kbserver.netgear.com/downloads_support.asp

[CrazyKen]

Thanks, loged in and found this in WAN setup PPPoE is not enabled and MTU size is 1458 can't find the other settings though?

Many Many Thanks, I will try it, got to go out for a while now but will post my results later, Thanks again

OH DEAR! I'm in big trouble now, used the tcp setting you sugested and my speed has gone completely to pot. 228 down & 277 up I have tried reseting to the saved tcp settings, no go, so I have done a norton ghost back of the hard drive to when I had just installed every thing still getting speeds of around 2 to 300 downloads, sitting with my head in my hands and crying.

here is a copy of the speed guide analiser, which seems to be the same as my original, WHAT HAVE I DONE.

Set it to the settings that I gave, reboot comp and then post a new TCP Analyzer to check if your TCP Window is set to 260912.

If speed is still slow with my settings, do a tracert to www.yahoo.com and post.

[CrazyKen]

I dont know if it makes any diference, but I niether of my computers are conected to the router I am conected by radio using belkin usb recievers, does this mean that no matter what I do on the computer I cannot affect the router settings? also how do I do a tracer route please.

Changing settings of a router should be done through an ethernet cable connection with the router and not on wireless.

You have irregular ping times at hop 1. Normal values would all be <1ms.

You have very high ping times at hop 2.

First, ensure your router and modem are placed a few feet apart and that both are placed a few feet away from any other electrical devices to avoid electromagnetic interference. After relocating your signal devices, turn their power off for 5 mins to let them reset.

Then do another tracert to see if your ping times improve.

[CrazyKen]

Tried all that earlier with no change. but I will try again. I have to go now as I have a gig to play tonight. will continue the saga tomorow. Many Thanks for all your hard work, talk soon.

Hi! I got back home this morning only to find that I now have downloads of around 4384 about twice the speed that I started with, I can only assume that the phone line or virgin must have had a problem yesterday, what a dat to choose just as I was making changes to my settings. at the moment all seems great!!!!
Many thanks for all your help not only sorted but learned a lot will keep you posted.
Ken.
P.S. search youtube for The Sussex Jazz Kings, thats me on the banjo.

[CrazyKen]

I am very happy with the increase in speed but can't help wondering if it is possible to tweak even further, what do you think?
