Hi All, I am using powerline for my ehternet (no choice so sticking with it) but I noticed that my powerline adaptors are occasionally crashing when I do a speedtest (over my 150mbps fibre using AV2 1000mbps plugs). My recived wisdom (via searching) suggests that reducing the MTU of the openvix boxes and my PC's from 1500 to 1450 may well fix the problem as it is due to the tiny buffers in the homeplugs falling over and panicking when they are overloaded with fragmentation. I can't do this on the consumer grade router I have for the LAN so I am changing the boxes and PC's. Done the PC's no problems but I sreated a script and put it into init.g that was as follows:

#!/bin/sh# Delay briefly to ensure the network driver initializes fully
sleep 5
ip link set mtu 1450 dev eth0

It didn't work. I am guessing that it is overridden sometime later in teh boot sequence so wondered if someone can point me to the right place to make this little change and to ensure it survives upgrades and reboots. Thanks all, Paul
 
by the way. For info. Changing he MTU on the PC's to 1450 completely stopped the crashing of the Homeplugs when I did the speedtest - thus it must have stopped the overloading of the homeplug buffers. This is deffo something I want to do on the openvix boxes too as they both use the homeplugs for comms and it makes sense to modify all the devices connected to the homeplugs so the whole homeplug landscape is protected :-) . Even though they will never (in the real world) use anything like 100 or 150mbps I do have the speedtest plugin installed on them both (for diagnostics) and it would be good to be able to run this plugin whenever I like to aid my diagnostics without crashing the homeplugs - even though they do reset just fine on their own in about 1 minute after they crash.
