Re: [Speed] Bandwidth issues when router is used (HELP ME figure
said by not :x2, and also a lot of consumer level devices are not going to be able to push anywhere near 100mbit, I would switch to a pc-based router running something like pfsense, and make sure your linsys wifi devices are only acting as AP's and not doing NAT on their own.
Tell me you're not using all those wireless routers and actually triple NATing everything as well as routing. I hope you have DHCP turned off on all the Linksys devices and are using the SonicWall as your DHCP and then all your LAN patch cables are plugged into the LAN side of those routers. If not, you're not properly using those routers are just APs, which is what you should be doing. Honestly, you should be working with just the SonicWall and some wireless APs/RE if you want things to work right, but since you're stuck with what you have, make sure you at least configure your devices appropriately and use them in the right way for the setup you have now.
Bottom line, make sure you're using the Linksys devices as makeshift Access Points.
