As it seems there was a bug in my sys_now(), wrapping-around at the wrong
value.
Now it works perfectly, thank you.

overflow of my sys_now()
function. I assume that it wraps around at 2^32-1, but I will cross check
it.

Hi,
I have a problem with LWIP, where after some time of normal operation, all
TCP communications die. After lots of headbanging, I found that tcp_tmr()
stops beeing called.
I examined the functions sys_check_timeouts() and sys_timeout(), and found
out that there is a problem when sys_now wraps a
,
but also I used my own computer's MAC (after disconnecting it from the
network), and no luck.
Only this specific MAC address works correctly, all other do not work on
the WAN.
Currently I am waiting our new hardware that utilizes an EEPROM
preprogrammed with a MAC address.

e the response, thus it
keeps sending the same request again and again. (This time for some reason
the microcontroller does not send the ARP request at all... Only responds)
Again the controller sends the UDP packet with no response.

C and tries to send the UDP packet,
again with no response. Obviously this will happen at a random time (the
app 30 secs delay I mentioned above).
It seems that the router has something personal with my microcontroller...

The ARP request is valid. It is a normal broadcast send to
ff:ff:ff:ff:ff:ff:, and the source is the MAC address that I have set to
the code. As it seems there is no problem there.

Lending??
No I am asking for the brand/model number of the one that you are
successfully using, to search for a new or used one. As you can image
buying lots of switches in the hope that randomly one of them will have
this functionality, is not an good idea :)

traffic, so I cannot be sure where the communication breaks.
Seems I need a debugging device.

On Mon,
Hi,
I am using LWIP 1.4.1 for a microcontroller project, based on the NXP
LPC1769 MCU. I do not use an RTOS and thus I am using the raw API.
I created the device drivers mostly based on the examples provided by NXP.
While a try any connection to my LAN, everything works perfect. However
