Hi,

I got following error from a NetGear wireless router, does anyone know
whether it is a configuration problem or a fault wireless router?

SNAP SSAP = 0; SNAP DSAP = 0 (both should be 0xAA)

Thank you.

Jim

Re: SNAP header error

NETGEAR model WPN824v2.

Sorry for not being clear, it is not a PC environment and the question
was for a wireless router configuration, not PC configuration. It is an
embedded system to connect to the wireless Router, the message was got
from dump of the raw data during the connection. The system can connect
to other NETGEAR mode such as NETGEAR model WGR614v7, but has the
problem particularly to one of the NETGEAR model WPN824v2.

Thank you.

Jim

What model Netgear router?
Where are you seeing this error message?  Log page?  Syslog?  Monitor
program?  
If on a PC or Mac, any particular make, model, operating system, or
configuration?

SNAP is SubNetwork Attachment Point.  It's part of 802.2 ethernet LLC
(Logical Link Control).  This might help:

There are several places where it might be coming from.  You'll see it
on a DSL modem when bridging between the ATM layer and the MAC layer
screws up.  You'll also see it on a PC network that has some ancient
MacOS machines running Appletalk.  I've also seen it on Novell LAN's
where there is high packet loss on the ethernet network (usually at a
10 to 100Mbit/sec transition point).
