Hi Donald,
Thanks for responding
The MTU seems fine.
This is the WAN link
pppoa-wan Link encap:Point-to-Point Protocol
inet addr:2.25.173.155 P-t-P:172.16.11.136 Mask:255.255.255.255

I sent a 1492 byte icmp request externally which got through.

rtt min/avg/max/mdev = 49.439/49.439/49.439/0.000 ms
So MTU looks fine.
Thanks

Hi Daniel,
I just saw your message on the LEDE mailing list. The freezing and catching up
sounds like a MTU problem. Could there be a MTU mismatch on the ADSL interface
(1500 <->1492)?

Hi,
I am quite desperate because I have a project going with these routers and I am
running really late.
Can anyone spare some time to help me, I am willing to pay an hourly rate for
the time if it will help.
This issue only occurs on ADSL. On VDSL performance is really good even using
PPPoE.
The issue is a sluggish access to the CPU interface via ADSL, so for example if
you are typing in a SSH client, it will keep freezing for a second or two, than
catch up.
Routed traffic is fine.
Thanks
Daniel

someone else did performance/throughput testing on the HH5A, the results are
posted here: [0]
I did not have time to look into this yet, but maybe Hauke or John have an idea
what's going on.
