I have a mini pcie wlan card which uses a mini pcie to pcie x1 adapter card. The adapter card has 2 threaded male connectors which look exactly like conventional rg6 but smaller. Those lead directly to the wlan chip with standard u.fl connectors.

I have an antenna from a netgear router attached to the larger connector.

My question is: what can I do to increase that antennas signal strength?

Alternatively, I have an antenna from a laptop that has a foam spacer and appears to be very intentionally and carefully designed. What can I use to replace or amplify that?

  • \$\begingroup\$ If I understand correctly... Tx is transmission and rx is reception. If so, I can only draw a parallel to upload/download. I care mostly for download. My problem is not bandwidth, it's signal range... \$\endgroup\$ Nov 21, 2020 at 6:54

Even if you are only downloading files, there needs to be both TX and RX, its not a one way communication like an AM radio. The router is probably using some sort of duplexer for TX and RX, you would basically need another duplexer and 2 amplifiers tuned at different frequencies, most likely an LNA and a PA, I'm sorry but there is no easy solution if you use that antenna.

Probably the easiest solution is to use an antenna with higher gain high gain antennas, the higher the dBi rating, the higher the gain of the antenna. Instead of hacking your wlan card, use it on the router.
