I hope someone can explain the problem I have with my wifi network. I do not have a telephone line so my wifi network is via a Samsung galaxy s2 mobile phone which I have set up as a mobile wifi hotspot which I am using via the tethering system. I have also set up a wifi repeater to reach parts of my home which were receiving a weak wifi signal. I have a Amiko hd890 satellite receiver box which is close to the samsung phone (approx 4 yards) which I acces the internet via the boxes wifi dongle/antenna. Now to the problem ----If I am using the box and it is the only thing connected to the network I am having intermittent results if you catch my drift --now if my wife starts using her laptop or smart tv to acess streaming services e.g. netflix my satellite box starts performing very much better and any intermittent picture etc dissapears, now I have heard that a wifi signal in some circumstances can be too strong ???? which I find hard to understand, I thought a good strong wifi signal was the ultimate goal. I have tried moving the phone further from the sat box but no improvement, I have tried using a wifi bridge for a ethernet connection but still the same. The only way to get things working properly is to have the two things going at the same time, I hope I have explained it properly - Any ideas ??????
