my thoughts, you dismissed my comments about your network not being up to the task but

here
you state your running Linksys WRT150N
which has a maximum connection rate on N band of 150 mbps, general thoughput is usually half so 75 mbps is likely the maximum theoretical thoughput
which assums it’s configured correctly for N spec and does not need to try and pass through walls or any distance or deal with interference from neighboring networks,cell phones, etc …
2 bars out of 4 is not good
as I already suggested, you need to increase your bandwidth if you don’t want studdering slow videos over windows shares
yes the retransmitts are an issue, but that’s likely caused by only have 2 bars, sounds like signal strength is likely down to the 50% neighborhood
