I used to run Overnet b4 I tweaked with Cablenut and I wouldnt get great DL speeds but now that I have changed the settings Overnet runs for 20 min. and my bandwith crashes. If I close Overnet and try to load a webpage it will take forever. The only way that I have found to correct the problem after that happens is to restart my PC.
Im on Cable with an advertised speed of 2048DL and 512UL (though I get speeds back from a test server of as high as 5000) (some settings I plug into Cablenet give me results like 9999999.9) pics that would take 3sec. to load will load in 1sec but then when I run Overnet I get bad results.
HER IS THE TCP/IP ANALYZER RESULTS;
TCP options string = 020405b40103030101010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 128480
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled Receive Window = 64240
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

256960 (MSS x 44 * scale factor of 4)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
580KB/S is the fastest stable speed I get when I do one of the FTP Speed Tests from OOL FTP.
I have tried to plug in many settings into Cablenut but nothing seems to cure this problem. When I DL with Overnet I have many DL's going at once but this has never been a problem till now.
WHY IS MY BANDWITH CRASHING? I need to be able to run Overnet and leave it. I cannot stay arround to babysit the program and to restart my PC all the time.
