As of Mar 3, 2013, Telus Optik TV is working. The Internet problem is fixed with a different router. Unfortunately, a separate router costs extra money. The article can be read at http://aprivatebeach.com/blog/2013/02/telus-optik-linksys-ea3500-router/
As of Feb 14, 2011, the TV has stopped freezing. Unfortunately, the wireless Internet still gets kicked off. I have decided to use wireless G. Therefore, it seems that using either wireless B or G works for stable TV signals, but wireless Internet is still a problem.
The information provided below is for reference.
I am currently having issues with the Internet going out. Furthermore, the TV freezes. Therefore, I called Telus to see if they can fix the problem.
They sent a technician to take a look and he did some repairs. Unfortunately, it did not work. Therefore, I decided to try something else.
Possible solution #1
The router supports both wireless B and G standards. Therefore, any wireless device should connect fine that uses these standards. In any case, I decided to try using a different wireless device.
The device I currently use is a Cisco Wireless-N USB adapter. The old one is a generic Wireless-B that can connect but not use the Wireless-G standard. The generic Wireless-B USB adapter has the option to either use auto or B. Therefore, it seems that it cannot connect at Wireless-G speeds.
Assuming that the problem with the freezing TV and the Internet disconnecting lies with that generic USB adapter, I changed it.
I will have to see if the freezing TV and the disconnecting Internet continues.
Possible solution #2
Another option, for those who want to try a quick fix, is to set the router to only use the wireless G or the wireless B standard.
The default is both, but it is quite possible that setting the router to only use one may fix the problem. I would recommend trying wireless B first. wireless B is an older (slower) standard, but maybe more common and used by a more wider range of devices than wireless G.
