Try and simplify the situation as much as possible. Hook your PC directly to your DSL/Cable modem. Run the computer for several hours like that. Monitoring the performance. Next add the Router back in but only with the PC connected. Next add one of the MACs back to the router, test, disconnect 1st MAC, connect MAC # 2, test. Finally add all three machines back to the router. These steps will help you isolate what elements in your network are part of the problem.
Additionally, are all of the machines set to DHCP? Mixing DHCP and manually coded IP addresses is asking for problems. I also agree with JinnKai, your machines need to thoroughly scanned by anti virus and anti spyware software.
By the way, be sure to be persistent when you talk to tech support. You should get a case number and write it down. Most call centers create a case number even if they do not tell you. This will help you avoid repeating yourself every time you call. If the person you talk to can not resolve the issue you need to demand to be passed on to the next level of tech support. They work in tiers, tier 1 support may do nothing more than answer the phone and forward you to the appropriate tier 2. Tier 2 probably has very little training and is reading from a script of questions. Tier 3 and 4 is where you normally find people that have actual training and knowledge.
