How can I get a stronger wifi signal?

[HiDood]

Hi all
I found the wifi signal very weak in my room as the router signal needs to go through 2 walls to enter my room. The internet is fine for normal internet browsing, but for gaming however, the ping is very high sometimes. Any ways for me to get a better signal without moving the router?
Thanks in advance

The best way would be to run an ethernet cable. Since that is not an option for many users. The second best option would be to install powerline networking. Powerline is likely to work but may not be satisfactory, so buy from a seller with a good return policy and install and test them right away.
