Is it possible to get a 4G wifi(mobile wifi router) with a late 2009 iMac? It changes always to H even there is 4G.

Even if you are in a 4G coverage area, there may be spots where the signal strength is not sufficient. That could result in the mobile broadband router/hotspot trying to connect to the mobile network (tower) at a lower speed. This has nothing to do with the Wi-Fi portion of the router/hotspot (Wi-Fi is used for the local connection between the router/hotspot and the computer). So, for 4G coverage questions, you should contact your mobile network operator. Good luck!

Hello Carola,

That appears to be a case where electric current flows in mysterious ways. 🙂

Any change with another position for the router/hotspot? Try various places (where the Wi-Fi connection to the devices still works).

Carola,

Which model 4G router is it?

The mobile broadband part and the Wi-Fi part of the router should not have anything directly to do with each other.

Normally, it should not matter whether you connect from a MacBook Pro, a mobile phone, a tablet or an iMac; the mobile side should behave the same. The only ways I can see that the iMac or any other device (theoretically) could affect the router's ability to handle mobile broadband would be through either interference (the Wi-Fi somehow disturbing the mobile broadband reception) or power (the Wi-Fi handling somehow causing the router to use more power, thus perhaps negatively affecting the mobile side). The available mobile bandwidth could also possibly have an influence (for example, heavy downloading only when using the iMac). Please note that the number of people connected to a mobile tower at a given time (and their network activities) can affect the mobile broadband speed.

Did you test the Wi-Fi connections one by one (that is, only one of the clients powered on at a time), with the router in exactly the same position?

Was the router running from its internal battery, or was an external power source used during the tests?

What mobile signal strength (number of bars) was indicated at the router? Any difference when the H was shown (instead of 4G)?

Hi Carola,

Glad to hear that.

BTW, while reading through the documentation for the Vodafone Mobile Wi-Fi R215 (and its Huawei counterpart), I noticed that two antennas are mentioned. Not so much more is said about this, but it appears to be ports intended for one or two external antennas for the mobile section of the router. If necessary, you may want to check this with Vodafone and ask them whether they would be in a position to deliver an antenna with the appropriate cables and plugs. Alternatively, a third-party supplier may have the parts. An external antenna can often improve reception substantially.

Regards,

Jan
