A good Wi-Fi signal is around -50 db
After about -70 db it becomes almost unusable.
The signal in the study doesn't seem to be very strong. I don't know where you have the wi-fi booster plugged in, but if as Gerry says the red network is the booster, then that's even weaker in the study. Is there somewhere you could plug the booster in that's halfway between the hub/router and the study?
I'm assuming you don't see your internet dropping out at all when you have the laptop in fairly close proximity to the hub/router?
Assuming that the issue is with the wi-fi signal strength, there are a few options.
1) You could replace your hub/router with a better one - generally, those supplied by internet service providers are mediocre. Using a replacement that has external antennae gives an added advantage of being able swap the antennae for higher gain variants - The only problem is that these tend to make the signal more directional, thus you could get a better signal on the ground floor of your home (assuming your hub/router is on the ground floor) but a weaker signal on the first floor.
2) You could try using a Wi-Fi dongle with your laptops/desktops to which you can attach an external antenna - I have one of these with two antennas - a +5db antenna that it came with and a +10db antenna I bought separately. With the 10 db antenna attached, I'm able to see many more wireless networks - but as yet I've not really roadtested it. If it's an option you are interested in, then I'll happily do some tests to see in real terms what difference it makes.
3) You could try getting a second wireless access point - almost any router will do - you can pop it in your study or somewhere nearer to your study and then connect it to the first access point using a network (cat 5e/6) cable. That way, when you are in your study, devices can be connected to the nearer wi-fi access point. If cabling is an issue, you could always try power over ethernet adapters. Again, they have their issues - they work best where both adapters are connected on the same mains ring. Sometimes other electric devices cause noise or interference which impairs them. There are also privacy concerns too - the network traffic between the power over ethernet adapters is generally unencrypted and if you happen to live next door to an avid computer hacker, they can buy a similar device and use it to sniff your network traffic. Despite the shortfalls, plenty of people swear by them.
4) Use network cables. In an ideal world houses would come with network cables and sockets chased into the walls. You might be able to run a cable under the carpets or perhaps neatly around the exterior of your home. Essentially, it's the one sure fire way of being able to always guarantee network connectivity without wireless issues - or running multiple access points connected via cable so that wi-fi just works better. But it also requires the most thought and investment. At home I have ethernet cables connecting a network switch in my garage to a network switch in my living room, and network cables connecting the "modem" to the firewall. Then other devices are either plugged into the switches or connected by the wireless access point that's plugged into the living room switch. As we redecorate, I'm planning to install more network cables so that hopefully, eventually, there's a network socket in nearly every room.
Finally, has the Wi-Fi/Internet actually ever been any better than this?
I am using a BT Broadband Extender 200 Kit.
unfortunately,it's winter now,hard to find bugs to photograph
