Re: [WISPA] Customer's web pages not loading/displaying properly

2012-05-10 Thread Justin Wilson
I have one customer we are dealing with this. Only happens on his Apple
devices (iPad, etc.) I can't reproduce it in the lab.

Tried adjusting his MTU (PPPoE customer) and other stuff. No Joy.

Misconfigured MTU values will produce results like this, particularly
noticeable on SSL-enabled websites.
If you can, try reducing the MTU down to say 1300 Bytes and clamp the MSS
to 1280 on a customer router to see if the problem goes away, if it does,
you'll need to work out where the MTU issue is on your network and resolve
it.

Re: [WISPA] Customer's web pages not loading/displaying properly

Saw this once when I was masquerading ALL of my clients to one IP address.

Subject: [WISPA] Customer's web pages not loading/displaying properly

 


This all started last Wednesday.  We have had about 15 WiFi customers that
are all getting the same symptoms. Pages will not load properly (attached
screenshots).  i.e. youtube.com video boxes are just solid black with no way
to play, this includes videos on msn, yahoo, etc.
  
Also most of times the page does not load properly (see attached, ignore the
teamviewer box on the images).  If someone is able to login to the yahoo
email they cannot check boxes to delete messages and with hotmail they
cannot select the emails at all.  We have not been able to isolate any
commonalities between the customer's computers, operating systems, antivirus
software, routers, radios, frequency, and even access points. At one point,
we thought that we had the problem narrowed down to Netgear routers but
after having a customer bypass it, issue still occurred. 

One of the customers had a computer consultant come look at their system and
when they switched to the consultants MyFi the problem stopped... Then as
soon as they went back onto our WiFi connection, the problem returned. 

Has anyone had something like this happen to your network?  Any ideas on
where to look next?

Seen that with Netgear routers and SPI.

Seen it with improperly routed networks.

Seen it with proxy caching.
