I am having a problem uploading to 2 web sites I maintain at Web.Com
Small files, 30kb or less go ok but I get an error Web,.com calls a time out when the file gets much larger than that .Web says it is not their problem. It fails on multiple PCs here using multiple FTP clients using Century Link DSL but dial up works OK. It also works if I take my lap top anywhere else, even the DSL customer right next door. I have plugged the DSL modem right into the Dmark with no joy. All other internet operations are OK including Emailing a large file or posting it on usenet. Speed tests range from 10m down/ 700k up to about a 3d of that using different test sites. DSLreports seems to be the slowest. Any ideas? I am thinking it has to be something with the actual wire going to the big silver box up the street that passes as a "central office" or the IP address I am using. Nothing else is common. Is there an easy to force an IP address change? Is it possible that I am just getting so many line errors that the FTP server gives up? Maybe the "fast" test sites only count bits, not good packets. Are errors logged anywhere? |

Do you know how to change the MTU in windows (temporarily) ? http://my.bergersoft.net/2010/05/13/...-xpvista72008/ If you want the third option, it's still here, in the Legacy Tools section. Normally your value might be 1500 or so. I can't check my WinXP right now, as I'm doing maintenance on the WinXP drive :-( And I'm on Win8.1 as punishment. http://www.dslreports.com/tools Paul |

I can't check my WinXP right now, as I'm doing maintenance on the WinXP drive :-( And I'm on Win8.1 as punishment. http://www.dslreports.com/tools Paul What would that do for me? That's a workaround for a Black Hole routing problem caused by the server end having ICMP turned off and your MTU happens to be too big. (Definition) https://en.wikipedia.org/wiki/Path_MTU_Discovery Apparently there is a modification to TCP/IP in later OSes, to fix that somehow. But I don't think it's present on WinXP. ******* Another thing you could try, is to use Wireshark packet sniffer and see whether any RST packets are being sent (they show as RST in Wireshark). As those can be a legitimate part of protocol that says the server doesn't have sufficient resources and would like to close the connection. https://en.wikipedia.org/wiki/TCP_reset_attack None of your evidence suggests that's what is going on, but I had a three month stretch where my ISP was randomly sending those. Right after they bought a Deep Packet Inspection box... Paul I doubt I am sending anything the server does not like since the same laptop, sending the same file works fine on dial up, on cable at my FILs house, DSL at the neighbor, using the same concentrator at the end of the street and a free WiFi connection at a business. It even works from here on dial up. I am still waiting to hear back from the Telco. I expect they will be back to work Tuesday. The tech support girl I talked to for 2 hours was clueless. She kept going to ask someone, or so she said, until we got cut off. She was probably handling other calls just to keep her cycle time down. This may not be the time for any of them to screw with me since I am throwing all of my services on the table this week and reevaluating how much I am paying for TV, internet, satellite, web hosting and whatever. I am even thinking about an air card but I expect that will be too expensive. |

I know it changes now and then anyway, I suppose when the lease expires |

I know it changes now and then anyway, I suppose when the lease expires If your router supports this, go to a computer that allows normal FTP access, press the Windows and "R" keys simultaneously, type "control netconnections" into the "Open" box and click "OK". Double-click the internet connection, then click "Details" and write down the "Physical Address". Then enter this address into your router. You may have to restart the computer for the change to take effect. Ben |
