I went through this at the beginning of the year, it get 900/900 fibre, settled on openwrt running on a nanopi r4s. My other options were a nanopi r6s with openwrt, or nuc type hardware/server running something like pfsence/opnsence etc. The openwrt install took about 5mins then a couple of hours of exploring various menus options etc, which I didnt end up changing.
I had a fake item sent to me, reported to eBay to request a refund, got an immediate refund, seller asked to return the item. I said no, its fake I’ll bin it. Left negative feedback that the items are fake. eBay then removed the review and let the seller keep selling. At least he had one less item to sell and was out of pocket on postage
