Default Wifi signal

Again, thanks to all who replied. I wasn't aware of apps that can check WiFi signal strength and will now pursue that fix.

I use Acrylic Wi-Fi Home to check WiFi signals.

I haven't seen any follow-up on your original note that wife's laptop couldn't find any wifi, not just your own, and would not even try to find one. As so many people here have wifi unless you have an isolated home out in Fenney, there should be many networks detected by the laptop. That is what makes me suspicious the problem is in the wife's laptop not your router. My laptop now is showing 7 networks other than my own.

Here is a google search that gives many suggestions of things to try:

The problem was the router, not the laptop. I got an app, at the suggestion of another TOTV poster, that measures signal strength. Signal was in the "poor" range. Comcast confirmed my router was dated (2 years old?) and is sending me one with greater range.

And now you know.

The new Comcast modem/routers are pretty good. We picked up a new one in May and the signal strength in our house has gone up quite a bit. Our Samsung smart tv previously showed us a signal strength of around 10 Mbps and now tests in the 70 Mbps range. Curiously when I set my iPhone down next to the tv it tests around 90 Mbps.

Still not convinced that it is the router. You haven't gotten the new one, so I (as a previous MS elevated tech) wouldn't consider your case closed, yet.
BTW make sure that your new router handles the latest 2013 transmission protocol 'AC'. Older ones' B' 1999, 'G', and 'N'. Best to have a device that will best handle your future devices. They recycle older modems so your 2 yr might actually be much much older. Look up the specs on your laptop WiFi card find out what transmission protocols it supports. 'AC' is the latest.

If the new router does not solve your issues, buy a USB dongle 'N' WiFi adapter, $10-$20 for the laptop.

I have seen WiFi signal strength in offices/ homes compromised by a dimmer light switch, wireless phone, wireless home theater speakers, older microwave ovens, and LCD blubs just to name a few. I also wonder if you have gotten any new appliances or WIFi devices. 2.4MHz and 5MHz are the WiFi ranges that are currently in popular use. 2.4 goes through walls/ material better and longer but suffers from slower speeds and bandwidth clutter. Even 1 other device that operates at a lower protocol could severely compromise overall system performance. I usually explain it this way: My Lambergini can go 200mph. But one of my tires is flat so I can't go over 10mph. In designing high-end PC's the performance falls to the weakest link. Networks can be affected similarly.

Keep us posted.

(Posted the above as general information so others could diagnose similar connectivity issues.)

agree on some of your points .. First an AC router is required for optimum performance .. But, most likely the current router picks the broadcast channel automatically .. recently there could have been some environmental changes affecting that selection .. The OP might not have the skills required, but it is relatively simple to go into the router and set the broadcast channel .. An internet search will reveal the allowed channels for 2.4 and 5 ghz transmissions .. that will show the "best" alternate channels to broadcast via trial and error ..

I appreciate these tech responses, but you are way out of my pay grade.

Linksys Extender AC750 Boost. Security wise if you select WPA2 are you secure? If not what is the correct thing to do?

Works great just security minded.

If you are a Comcast customer you should go to Xfinity.com and test your wifi signal with their speed test app. Do you know what wifi speed you are paying for? If you are only getting speeds in the 20s then I would let Comcast know and they will fix it. I had a similar problem and they checked it out and ended up giving me a new router that is capable of 400mps. That definitely solved the problem. I pay a little more but definitely worth it. I like you also only stream TV with Roku and Hulu and the faster the speed the better ie no buffering.
