Need a coffee shop or room in Warsaw with Ethernet port not just WiFi

A LAN port is also known as an Ethernet port. I am looking for a coffee shop-type place where I can connect a cable to an RJ45 type plug? In other words, connect my laptop via cable instead of their wifi? . Is this possible in Warsaw?

You'll be lucky! To find an Ethernet port anywhere. Old tech - I haven't seen Ethernet anywhere outside a hotel in a decade, and never saw it in places like coffee shops.

Hotels might still offer it.

I would suggest a wifi device connected to your laptop via usb, or Ethernet which will then connect to the wifi of the shop you are in.

Likewise.

His or her best bet is to become friendly with someone who had a small coffee shop and see if it's possible to connect via cable to their router.

sneak into a uni lab/lecture theatre?


Yep, bring your own 5m ethernet cable tho.
