I have a issue with the moneris pos system at a friends store. about 40% of the time it rolls over to the backup dial up system when processing transactions. We have chatted with the techs and they don't have any ideas, we have replaced all cables, installed a new twgbrf114 Trendnet router, which is directly connected to Bell Canada 5200 speedstream modem. I think i have the proper ports open 443 as 60% of the time it works without issues. We have also chated with Bell techs (getting nowhere)
it is a very simple network, two computers and two POS units all static IP into the router, and out to the modem.
happy to provide information that is needed if i missed something.
thanks for reading.
