When in group chat, skype has bad connection and games lag

Question

Okay so I have searched almost every related post and cant find this exact issue and ive tried all the standard stuff to fix internet issuesWhat happens is So I moved to a new house and had no internet for 2 weeks starts may 20th about, and we got internet around june 5th. Ever since then when I join a group call with my 5 local friends Ive been in a group call with for 4 years i have bad connection and when i play online games it lags. It use to affect my internet browser, google chrome by making stuff stop loading but that isnt the case anymore. I have tried many things. Like recently I join skype group call and it seems to be fine but once i join their terraria server both skype lags and terraria and I end up losing connection. I have a theory but there still a lot of variables. Whenever my one friend is in the group call i lag a lot more than I usually do, but not everytime, and sometimes i still lag when hes not in the call. Its also him hosting the terraria server where its really bad. It has been like this for other games too though and I have tried many solutions. I feel like maybe its a bandwith thing but i get over 100 mbs download speed and around 15 mps upload speed and low ping. I can also download 2 games and play a online game with 0 problems but once skype is involved it becomes terrible.I really would like a fix, I have used skype forever and I dont think my friends really wanna use anything else.I got windows 10 about a week ago, the beta, but it did it on windows 7 too.I have also tried downloading older skypes but it keeps downloading the newer one automatically even with automatic updates off.Also when I lag on skype the little refreshing/connecting icons comes up and I lag to my friends, but I never hear them lag.

If you are swapping out operating systems and nothing is changing then the variables you need to look into are: 1,  Your wired/wireless connection.  Try wired if going wireless as you may have issues sustaining a good connection with the myriad of ports Skype uses.  This can be due to distance, interference or other factors. 2,  Try bypassing your router and go directly connected to your modem (if possible).  Issues with the router firmware, its configuration or the limitations of the  router itself could be causing bandwidth related issue.  Going wired to the modem would be ideal.  3. You can try disabling/enabling uPnP in your router to see if that makes a difference.  Some routers handle uPnP well, others have performance issues with it.  4  Cable modem/Line issues -  You could have stability issues due to the quality of the modem based off standard/tier.  You could have line conditions that affect upload/download stability or both, under load. I've had issues with Skype that were related to my wireless router firmware.  I've also had to swap out my modem to a more compatible and higher tier one (twice) when my ISP performed infrastructure changes.
