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

Re: [WISPA] Customer's web pages not loading/displaying properly
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. From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Mark Theis Sent: Wednesday, May 09, 2012 6:29 PM To: WISPA General List 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? -- Thanks!

Seen that with Netgear routers and SPI. Seen it with improperly routed networks. Seen it with proxy caching. Regards, Chuck On Wed, May 9, 2012 at 7:41 PM, Josh Luthman wrote: > Seen that on Trango.
