Does ifconfig show dropped packets/errors? |
| 25 |
|

Is the mtu the same on MSWindows and Linux host and router? |

MSWindows can corrupt its TCP/IP stack, or if you try to modify its parameters |
| 29 |
too much (size of receive/send window et al) things could go wrong. There is |
| 30 |
some Microsoft fix file for this (I recall one available for WinXP at least) |
| 31 |
which resets the stack to its default values. |
| 32 |
|
| 33 |
On the odd occasion I had to stop/start an MSWindows connection which would |
| 34 |
not come up on boot up, but this hasn't happened for quite some time now. It |
| 35 |
might have been dodgy firmware on my router; I don' know and never found out |
| 36 |
what was the cause of it, because it only happened a few times. |
