multiple wireless connections

[ennaoj1977]

is there a way of stengenthing your wifi signal to cope with all the wifi devices connecting to it? (mobiles, tvs, game stations, laptops etc)

Yes but limited.

You can relocate transmitters (routers) to higher points or locations away from things that interfere with the signal. You can extend the distance using access points. You can change frequencies and channels to avoid congestion and overlap with other wireless networks.

But overall, the output signal strength is regulated and restricted with respect to power.

The other aspect is bandwidth. If there are too many wifi devices competing for the bandwidth then network peformance will be slow regardless of signal strength. Even allowing a that a stronger signal can "get through" more often.

Try connecting more of your devices using wired ethernet. That will take some pressure off of the wireless devices and possibly improve the performance of the devices that become wired.

A more specific answer will require knowing more about your situation and network. For example if no wired connectivity is possible or otherwise unacceptable then there are fewer possible solutions.
