Question about Intel Dual Band Wireless-AC 7265

I bought this card for my HP EliteDesk 800 G1 Ultraslim. Card fits and is recognised in Win10, but the signal is extremely poor. 30cm from the router I have just 2 bars. Now I have to look for suitable antennas. Anyone have a suitable idea?

Hello,
I can't answer that either,
I once replaced the wireless module in an Acer aspire laptop,
and it worked fine,
if it has a M.2 PCIe connector on the motherboard it worked.
antenna is connected internally to the module.
Would have to see the inside of the unit,
would be helpful to you, still have such a module, new.
greetings
