Tried to connect laptop via LAN cable (straight one) directly to the miner, no network hub. Configured the laptop network as specified to IP 192.168.168.100 and tried to access 192.168.168.168 (the miner in setup mode). Not successful.
Connecting your miner to a PC isn't all that simple, I have written a simple guide which you could follow here >

I don't use Avalon gears, but common sense is that if the miner is set to static ip, you have only 2 ways to sort this out, 1- Reset the miner to factory (which you seem to be having issues with) 2- Configure your router to work with the miners static ip, contact the person you bought them from and ask them about their gateway/router IP address and use that on your router.
I am sorry I can't help any further, if this was Bitmain related I would have probably helped you a lot more, try to reach out to
