To start with your network setup if fucking insecure (has nothing to do directly with the performance). Incase you don't have the funds try to get a basic firewall setup (something like pfsense)

If the slowness is coming time to time there can be multiple reasons
  1. Some asshole downloading stuff from the internet since you haven't controlled that
  2. Network congestion because of the number of users using wifi (not sure how many can be handled using a single AP. You need to check that)
1. we have no control or monitoring in place. this may be the issue..
2. tplink 450mbps access point. two of them handling user load.

depends on the where the network bottleneck is
btw what's the internet link in the office? is there any monitoring done on this uplink?
is it going through a firewall? is your server segment located in a seperate vlan or is everything located in the same lan?
I think it would be better if you post a rough diagram with link info.
I doubt it's a problem with your cabling
slt fiber connection. no monitoring done on uplink.
not going trhough firewall
all are in same lan
no cabling is done. all laptop are connected via wifi. only server is connected with cable.

    If you got the budgets try to buy a fortigate firewall. A entry level one will do. You can replace tplink switch the firewall. It will act as a router and a firewall. Will also provide you monitoring and control as well.

    Machan, Get your company to invest a bit and setup a proper secure network machan (proper firewall. Cheap working options would be fortigate. A good AV etc.). It might cost a bit but It is worth the trouble. You guys seem to be fucking unsecure and trust me slow internet is the least of your problems. The day you get hit by some ransomware or something is when you start shitting your pants.

    මගේ කාමරේ
    මුලින්ම ඉන්න users ලා දෙන්නෙක් temporary Ethernet cable දාලා direct switch එකට connect කරලා දවස් කීපයක් වැඩ කරන්න දීලා බලන්න slowness එක එනවාද කියලා. ඒත් slowness එක තියනවා නම් ගොඩක් වෙලාවට SLT fiber line එකේ අවුලක් වෙන්න පුලුවන්. එහෙම නම් SLT එකට complain 1 දාල ඒක හදාගන්න. Direct switch එකට connect කරපු අයට හොඳට වැඩ නම්. අවුල තියෙන්නේ wifi වල.

    ඔය දාලා තියන access point home use වලට හදපුවා. ඔය වගේ වැඩකට ගැලපෙන්නේ නෑ. Concurrent users ගාන වැඩි වෙනකොට issues එන්න පුලුවන්. අනික ඕක support කරන්නේ 2.4GHz විතරයි. 450Mbps කියන්නේ මාකටින්. real world එකේ ඔය users ලා ප්‍රමානෙත් එක්ක හම්බවෙන්නේ aggregate 20-30Mbps අතර. Ruckus, Aruba, cisco (non SMB) වගේ dual band enterprise AP එකකට මාරුවෙන එක තමයි හොඳ. ඒවා ටිකක් ගනන්. ඔය වගේ workload වලටම හදලා තියෙන්නේ.

    අනිත් අයත් කියල තියනවා වගේ පස්සේ පොඩි ෆයර්වොල් එකකුයි endpoint protection එකකුත් දාගත්තානම් කිසි කරදරයක් නෑ
