I think my bedroom is in a deadzone

I recently purchased a Vizio smart tv (model M322i-B1). When I put the TV against the desired wall and set up WiFi, the connection test showed speeds varying from 300-100 kbps, and often failed the connection test. However, the connection is showing full green bars. When it did succeed in the connection test and I tried to watch Netflix, the quality was poor, and stopped streaming to reconnect often. I thought the router/modem was the culprit as I have had similar issues connecting to a WiiU in a different room but nothing as bad as the TV. I purchased a new router in hopes that this would solve both issues.

Since purchasing the new router, the WiiU problems have ceased but the TV problems remain. I thought I would try moving the TV around on the same wall in my bedroom and found the connection problems to be unchanged. When I moved the TV into the same room as the WiiU, the connection speed improved dramatically, coming close to 1100 kbps and having zero issues connecting or streaming on Netflix.

Through testing locations of my TV throughout the bedroom in question, I've determined only the one wall causes any issues. However, I'm puzzled that the connection strength remains at full green bars regardless of the distance from the router(approximately 26 feet away from the router is the deadzone).

Why does the connection speed drop but the connection strength remain the same?

I've read that some things tend to interfere with the signal strength as the distance from the router increases. What type of things should I be looking for when trying to determine the culprit of the dead zone? The WiFi signal only travels through 1 wall on its way to the trouble zone, does the proximity to a second wall have anything to do with the problem I'm having? I have tried unplugging baby monitors, phone chargers, TV antennas and nothing helps.

Model of TV in question: Vizio M322i-B1
Old modem+router: ZyXel P-660HN-51
New Router: TRENDnet TEW-812DRU
# of wireless connections: 1 TV(the one in question) 1 WiiU, 1 iphone 5, 1 iphone 5S, 1 iPad4(model A1459), 1 Nest thermostat, 1 PC( no problems with it). total of 7 wireless
1 Wired PC with no problems.
I live in a suburban neighborhood, and the houses are spread out so I don't see many conflicting WiFi names, maybe 3.

Any advice would be appreciated! Thanks!

ok, seriously, can your router operate at 5Gz? 2.4GHz has a lot of stuff that can affect it from microwaves to cordless phones.

also, it's possible that behind that wall are a bunch of electrical cabling, perhaps not properly shielded.

We also actually don't know what the bars on the TV truly represent. They may consider "signal strength" = "latency" or something. Or the calibration is off, they may consider 4 bars = -10dB even though thats not a particularly strong signal.

Then there's the issue of interference from other wireless networks although you say the issue is just with one wall, and everywhere else it works fine. so maybe that's not it.

one other thing is that the signal of a wireless router is not a "sphere" it's more like a donut depending on the orientation of the antenna(e). It's possible that that wall sits in the hole of a donut.

I did do some more research into the products and found that while the router does transmit 5Ghz, the TV only picks up 2.4GHz(unless there is a way to manually make it connect that i'm not familiar with). Probably some research i should have done before blindly buying the new router(but hey, new toys). I think for now I'm going to just return the TV and save up for something newer that can handle the 5GhZ.
