I just wanted to take a minute and thank you guys for this thread. I found it via a Google search and it along with some of the other threads here really helped me figure out why I've always hated my wireless performance in my home.
After getting comfortable with the thought of separate devices, I bought the Cisco RV042G and two Ubiquity Unifi AP's - both recommended in this thread. I also bought two switches, a pair of ZyXEL powerline adapaters, and a bunch of 15' Cat5 cables. After some initial setup headaches, everything started working, and I can NOT believe the difference in performance. Anywhere we go in my two-story home we are getting three-bar wireless signals across all devices. I'm absolutely loving it.
Two things I had to do to get the Unifi's to work. The first I still don't understand, but I had to set them up with static IP's to get them to show up as an AP for any device. At first, I just wired them to the switch and set them to DHCP, but this didn't work. Thought they might be broken, but both of them? Nah - trial and error and frustration finally prevailed again. Secondly, they don't like SSID's of only three digits. No idea why, but they will not broadcast the SSID "OFF", but have no problem broadcasting my new SSID "ROTFLMAO".
One cool thing I did just for kicks was scan the floorplan of my house and load it into the Unifi controller software. What a cool toy! My whole house is now in the yellow (i.e. best) coverage zone!
I did have one other issue that I'm wondering if someone could provide some insight on - the issue is gone now, but it could pop back up. My personal desktop PC is hardwired to the new Cisco router, and I use it to do the basic setup and admin stuff for the router. After setting everything up, this PC's network/internet performance was just what you'd expect from a wired connection - flawless. However, something (I have no idea what) changed and it (network/internet) suddenly slowed to a crawl (some known live websites wouldn't load at all) even though all other devices - wired and wireless - still functioned normally. This includes extremely sluggish performance in logging into the router for admin purposes and switching pages within. This went on for a day and a half while I fretted over what I'd messed up. Then, it went away after several reboots of various pieces of equipment including my PC multiple times. It started to come back briefly, but seemed to quickly fix itself and hasn't occurred since. Does this sound like something obvious to any of you? i.e. is there a "first thing I should check" next time it happens?
Again - thanks for the tips. I love, love, love my new setup. Netflix streaming is flawless in HD on two TVs simultaneously now while my son games in the other room. Fantastic!
