Along with the NIC I have ordered a new SSD to build a new 2.9 system on Debian 11+ (keeping this install in place for now). I read on
www.gnipsel.com/linuxcnc/debian-11-emc.html
that the 5.10-18 realtime kernel is most reliable. I expect there is a way I can restrict synapsis to installing just that version?
I also have been reading around the subject quite a bit, seems that the Realtek NIC's are most problematic (hopefully resolved with the Intel) but Intel NIC's require some tweaking.
Some references which seem to point to mismanagement of NIC drivers in certain kernels:
My problematic hardware thread uses the 6.1 kernel. I did read somewhere yesterday that intel had made some contributions that improves network performance. Not sure if it has got to the 6.2 kernel yet...
Okay, perfect. Thanks for the info. The new NIC should be here shortly so I'll get a look more deeply at this over the weekend. I may just try the new NIC as is to see if we get anywhere as the new SSD I have ordered might be some time out yet.
Just as a quick update to this. I dropped the Intel NIC in, after disabling the onboard lan controller in the bios it worked out of the gate without any config. I have test code running atm on the router. So far so good. I understand there are some intel specific tweaks that might be necessary, ill dig those out soon and apply/try them here. I intend to update the 2.9 non the less as I am running one of the earlier releases and haven't updated it for some time so will see how that goes. Ill keep this updated as I test this out. Thanks for the help gents. Hopefully at 20 quid this was a cheap fix
