Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I have been testing 5 PicoW's running 5.07.07a19 and 5.07.07a21 connected to a TP-Link TL-MR3020 router (stand alone, no internet),
all working  great, no issues. They have been running for dayes now.
I am using Tera Term and Wireshark to monitor.

Then I switch PicoW1 and PicoW3 to a Huawei Soyealink B535-333 router (with internet) and some issues showed up.



"Unable to connect to this website 192.168.8.112 took too long to respond.
ERR_CONNECTION_TIMED_OUT"

It takes from minutes to hours before it stops responding to a page refresh. Same experience with PicoW1.
The only  way to get it working again is a Power reset. The MMBasic seems to be working ok.

Anyone have an idea what's going on? My knowledge of tcp/ip communication is limited.

Sorry for my english I'm from Denmark

Start by updating your picoWs to the latest firmware.
a28 has a lot of improvements which might solve your problem.

You can use the version in the first post on this page
https://www.thebackshed.com/forum/uploads/matherp/2023-03-21_181400_PicoMiteWeb%20(4).zip
or the a28 from earlier in the same thread.

Thank you Jim.
All 5 PicoW's are now reflashed and running a27 as firmvare.
2 are connected to TP-Link TL-MR3020 router (7 years old).
3 are connected to Huawei Soyealink B535-333 router (6 month old).
I will now let them running and see what happens.
My goal is to use one to monitor my caravan situated 50 miles away, therefor reliability is important, too long to drive in order reset the PicoW.



Greetings

The 3 PicoW's connected to the Huawei Soyealink B535-333 router all failed.
Then I switched PicoW1, PicoW3 and PicoW4 to a Huawei B525s 23a router.
After a short time PicoW4 stopped with an error.

How is this possible ??

Restarted PicoW4 and all have now been runnig for 40+ hours, great.

My conclusion: the Huawei Soyealink B535-333 router has an issue with the PicoW as an IOT.
I will now ask my ISP why (both Huawei router has been supplyed by them).
Now I am able to continue with some more exiting programing.

Thanks to Peter's and Geoff's great work, which gives the Rpi Pico a very big advantage, built-in "OS" with a very advanced Basic programming language.
Many thanks Peter and Geoff

Try extending the timeout
OPTION TCP SERVER PORT 80, 10000
