Sure it does. For every packet dropped on the floor, equals approximately another packet that has to be resent from the far end. This becomes worse if the traffic were UDP, for example - as it's stateless.
I think the OP needs more bandwidth...I'm trying to imagine how there's even enough upload bandwidth if, for example, he and his son were gaming with audio and/or video enabled.
I basically agree with you, but if video is not enabled, you should be able to run 2 game streams and 2 VoIP streams on 2Mbps upload... But just barely... If you have say 6-10Mbps upload you will be much more comfortable.
That (good) hypothesis is easy to test, install (@snoop I am talking to you here, not @lleachii ) iftop on the router (opkg update ; opkg install iftop) and rund it against the the wan interface (to test this look at the l3_device otr the device reported from ifstatus wan) by issueing iftop -i $MYWANINTERFACE, obviously replace $MYWANINTERFACE by the result from the ifstatus query....
That should allow you to monitor the network load generated by one or two of the connected devices to figure out whether the upload is the limit. As a rule of thumb a VoIP-quality voice channel requires around 100Kbps, video will require more....
Issue a cmd iftop -i $MYWANINTERFACE
Am I missing a step?

root@OpenWrt:~# iftop -i $MYWANINTERFACE
iftop: unknown option -i
iftop: display bandwidth usage on an interface by host
Synopsis: iftop -h | [-npblNBP] [-i interface] [-f filter code]
[-F net/mask] [-G net6/mask6]
-h display this message
-n don't do hostname lookups
-N don't convert port numbers to services
-p run in promiscuous mode (show traffic between other
hosts on the same network segment)
-b don't display a bar graph of traffic
-B display bandwidth in bytes
-a display bandwidth in packets
-i interface listen on named interface
-f filter code use filter code to select packets to count
(default: none, but only IP packets are counted)
-F net/mask show traffic flows in/out of IPv4 network
-G net6/mask6 show traffic flows in/out of IPv6 network
-l display and count link-local IPv6 traffic (default: off)
-P show ports as well as hosts
-m limit sets the upper limit for the bandwidth scale
-c config file specifies an alternative configuration file
-t use text interface without ncurses
-o 2s Sort by first column (2s traffic average)
-o 10s Sort by second column (10s traffic average) [default]
-o 40s Sort by third column (40s traffic average)
-o source Sort by source address
-o destination Sort by destination address
The following options are only available in combination with -t
-s num print one single text output afer num seconds, then quit
-L num number of lines to print

I hope I did it right... It's a lot to take in right now. 8 hours sleep 3 days oh boy... LOL
You ssh from the LAN side into a LAN port. ifconfig will list all your network interfaces and there will be one with your external IP. You use that name in iftop. If you are using DHCP, it will be eth0 or eth0.2 or similar. If PPPoE, then it is pppoe-wan.
