College Internet Connection

[Deftones2307]

I recently moved into college and hooked up my computer through their data jack in the wall and I'm not quite sure what connection they use but it has been really slow and need some help making it alot better. Here are my TCP Analzer results. Please help.

TCP options string = 020405640103030201010402

MTU = 1420
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1380
Maximum useful data in each packet = 1380, which equals MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 1380
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 345
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
507840 (MSS x 46 * scale factor of 8)
253920 (MSS x 46 * scale factor of 4)
126960 (MSS x 46 * scale factor of 2)
63480 (MSS x 46)

bandwidth * delay product:
Your RcvWindow limits you to: 55.2 kbps (6.9 KBytes/s) @ 200ms
Your RcvWindow limits you to: 22.08 kbps (2.76 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 53 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Take a speedtest from Here (http://speakeasy.net/main.php?page=sup_pops) and the post the results, so we roughly know what speed your connection is. :)

2002-09-01 20:31:39 EST: 1096 / 3056
Your download speed : 1096734 bps, or 1096 kbps.
A 133.8 KB/sec transfer rate.
Your upload speed : 3056546 bps, or 3056 kbps.

Your upload speed is much faster than down.. have you tweaked?
Seems like broadband .. above the 1mbit barrier!



Please help me

What OS are you using and what kind of speeds are you supposed to get? i.e. your supposed rated speed on their LAN. First read the Help & Tips link in my signature and try and fix your MTU.:) :D

[Deftones2307]

I am running Windows 98 and I have no real clue as to what speeds I should be running but they are god awful terrible speeds. I swear 56k would be better.

[mnosteele52]

OK download the TCP Optimizer (http://www.speedguide.net/files/TCPOptimizer.exe) and try the following settings.

Settings tab:

select - cable modem
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1500
TTL - 64
TCP Receive Window - 64240
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 Options - uncheck both boxes*
(* if using TCP Receive Window of 65535 or higher check windows scaling)

Other Settings tab:

Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized

Then select "Apply Changes" and reboot to take effect.

Then please post another TCP/IP Analyzer test and do 10 speed tests from Speakeasy and post the average of your top 5 results, then we can go from there.
:) :D

Ok I tried changing the setting but they did not save and I tryed a couple times and no luck. Here are my current settings.

This is really frustrating considering they boast about their top of the line networks and connection speeds and they turn out to be nothing but crap.

[mnosteele52]

It's not the colloge, it's your settings:(. Try downloading Cablenut, it will overwrite any previous settings.:)

[Deftones2307]

Cablenut also failed to set the settings correct and they are back to the original ones that are crappy.

Can I have your upload speed? :D

Only if I can have your download speed

[Deftones2307]

Damn this is really annoying, I can't even play Counter Strike because I constantly get CL_FlushEntityPacket error like everytime. DAMN DAMN DAMN!!!!!!!!!

Apply the speedguide patch for your OS.

[Deftones2307]

Even after installing the speedguide patch all the settings are exactly that same.

[Illini25]

Only If we could combine our connections........DAMN!! That would be nice, lol

[Fudgemaker]

try unplugging yoruself from the connection temporarily just to see if you can go to your registry where the keys are located.. and see if they're different when you aren't connected. If they are, that means that your connection is limited to certain settings and you can't change them, but it would also help if you upgraded to windows ME, or windows 2000, or even windows 98 SE for that matter.
