So you want to connect an external antenna to your router, but this does not have a removeable antenna? That's where we can help (probably). We can modify most routers. The existing, fixed antennas are removed (one or two), instead of the antennas cable jacks are installed. Then you can attach any antenna to these connectors. We will install RP-SMA jacks, which are the most often used types for WiFi equipment <snip>
How complicated is this operation for newbie in electronics?
Is this somehow possible to do also on the F5D7130?
