MiFi4510L sporatically hangs on Web sites w/ IE Win6&7 (THIS URL!); TCP Segment Lost

  I had to use Dial-Up just to get this far!!!

 

  Sometimes it works fine; other times it hangs FOREVER (TCP Segment Lost)! Must manually STOP..

I've let it hang for over 10 minutes; nothing ever happens after the last trace entry. No re-xmits.

 

  The last time it hung, I collected dumps&traces, then Stop & Refresh in IE and it worked fine.

During the hang, I successfully TELNET'ed to the DNS (same IPAddr), so it's NOT apparently a connection issue.

Certainly YOUR OWN URL should NOT be having constant problems!

 

  I powered off&on your device. Still occasionally hangs.

 

  WHAT IS GOING ON? The only solution seems to be to use Dial-Up!!! I have NEVER had this problem in all the many years

using Dial-Up.

 

  Here are NETMON traces from a recent hang

Hi MtheK, 

 

My understanding is that you have the 4G Mifi and it is losing connection, correct? Are you using Dial-Up to connect, or are you using the Mifi to connect?

 

Please provide some additional details, as well as any error messages you are receiving. We want to make sure your service is working. 

 

Thank you!

  It's not that the connection is lost, just the specific URL hangs. I can TELNET via a
DOS prompt to the same IP address just fine while this FOREVER hang is occuring.
Of all the URLs I use daily, only 3 (of about 50) would consistently, but "randomly",
hang; the GOES IR and WV .jpg, and your site (which is why I had to open this post
using my Dial-up; I could NEVER get past your login). Different IR and WV .jpgs, in
completely different URLs, would work fine when the bad ones would not:

BAD

http://www.goes.noaa.gov/GIFS/ECIR.JPG
http://www.goes.noaa.gov/ECWV1.html  (the .jpg, not the .html itself)

GOOD

http://www.ssec.wisc.edu/data/east/latest_eastir.jpg
http://www.ssec.wisc.edu/data/east/latest_eastwv.jpg


  This particular hang does NOT & has NEVER occured when I use Dial-up @ 56Kbps
to the GOES IR URL.


  It SPORATICALLY occurs when I am connected to the 4510L via Network&Sharing/WiFi.
If I delete my Temporary Internet files in IE, I can USUALLY cause it to hang
while trying to logon to your site, as well as the GOES URLs.


  What I provided was a NETMON trace. The lone 0x1 is the 'TCP Segment lost' GUI column.
I would provide a screen shot, but there doesn't seem to be a way to upload a .jpg
in this forum. This was from another hang that I analyzed more in detail:

  Lately it hasn't been occuring. I just tried forcing it to fail, but I can't,
even using the same methods I used before to make it fail most of the time,
both the GOES URLs and your site, so all I have now are the traces when it DID fail.
I use the GOES IR URL daily, and, so far, it's worked every time the past few weeks
(almost since this original post).

  OK, it failed again yesterday. Here's detail from NETMON including entries proir. #11104 is the detected failure.

Have to do this post in multiple entries due to character size restriction:
