I am a helicopter pilot and I have some spare time at work and have been asked to help fix the employees network. It is a network that has both wired and wireless connections and has a DSL modem to connect to the internet. This is a network that has no manager or controls and is more a labor of love than a necessary need for our business. Or problem seems to be a problems of packet loss. I have tried several tools that do analysis on the network and it seems as if we are having greater than 50% packet loss. Any ideas where to start finding the solution?

TCP options string = 020405980103030201010402
MTU = 1472
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1432
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 257760
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64440
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
504064 (MSS x 44 * scale factor of 8)
252032 (MSS x 44 * scale factor of 4)
126016 (MSS x 44 * scale factor of 2)
