Hello, 
sorry as i was testing with modems .. was offline for a short while ...

YES, I'M absolute willing to do testing :)


ZBT 3526 is coming as default with 512MB RAM and 16MB flash as default ....
but can be ordered/extended to 32MB flash (cost only ~5$ more)
=> so, there are only 2 versions possible
see also: http://www.zbtlink.com/products/router/ZBT-WG3526.html
Hardware	
MT7621 dual-core
Flash:16M (optional 32MB)
Ram：512M

ZBT 826 is always coming with 128MB RAM and 16MB FLASH as default ....
but can be ordered/extended to 32MB flash
=> so, there are only 2 versions possible
see also: http://www.zbtlink.com/products/router/ZBT-WE826T.html
Hardware	
MT7620A  
Flash:16M (optional 32MB) 
Ram：128M


both models can be got with: epci USB modem: "hua909-521 module" (cost around 80$)
(which makes sense, otherwise only an expensive lan/wlan router) :)

=> they are working smooth and fine with packages:
#3g/4g + luci (https://wiki.openwrt.org/doc/recipes/3gdongle)
opkg install chat
opkg install comgt
opkg install luci-proto-3g
opkg install kmod-usb-serial
opkg install kmod-usb-serial-option
opkg install kmod-usb-serial-wwan
#3ginfo package
opkg install http://dl.eko.one.pl/chaos_calmer/ar71xx/packages/3ginfo-text_20170106_all.ipk --force-checksum
#opkg install http://dl.eko.one.pl/chaos_calmer/ar71xx/packages/3ginfo_20170106_all.ipk --force-checksum
#option overwrite with own apps....
#debugging GSM modem:
opkg  install picocom --force-reinstall

if needed - i have also factory binary which is supporting 32MB...
i can install that as well to get information on the mtd layer.




for testing:
