Hi, I am just at the edge of having WiFi access to my office about 200m away with one tree partially obscuring clear line of sight. My office has 2.4 GHZ WiFi. I bought a TP-Link CPE210 thinking this would do the job. It does, sometimes. I can join the office network in client mode and signal strength can be say -80 dBm, but frequently the connection is lost. I am interested in getting equipment that will let me more reliably use the office WiFi. My budget would probably go up to about 200 EUR, but I'd prefer not to spend that much. Also, my landlord does not allow dishes outside our flat, so I'd prefer something discrete - outdoor mount is OK.
The simplest idea would be a router like the CPE210 but a higher gain antenna and good electronics for long-range signals. I cannot find the CPE220 (with a 12 dB antenna instead of 9 dB) for sale in Germany, but if I could, would the 3 dB increase in gain likely make a substantial improvement? Are there other routers with good directional, high gain antennas that might be recommended?
One idea is to get a YAGI antenna and a router. In that case, what routers with external antenna mounts have particularly good range? Any antenna recommendations?
I am in Germany and would prefer to buy from a German store.
Thanks in advance.
