Actiontec GT784WNV wifi signal transmitter problems

[tomva]

    I purchased a Actiontec GT784WNV from Amazon three months ago and set it up

with minimum effort.   It worked well on both ethernet and Wifi until recently.

My main PC  was on wifi and started having problems while the second PC

worked OK on ethernet.  I moved the modem to connect the main PC to ethernet 

with sucess.

   The second PC (now on wifi) now has a very slow and erratic connection. 

The problem showed up using my main PC wifi card and two different 

USB wifi adapters on the second PC.     In addition, my TV wifi  netflix  wifi  also

stopped working.   These tests indicate to me modem transmitter problems

even though the wifi signal bars show a strong signal.

       I have reset the router which helps for awhile.  It has good ventilation and

does not appear to be overheating.  I have tried channel 6 and 11 on the

modem without helping.

Any ideas on how to confirm the Actiontec transmitter  is broken or how to fix?

There are couple of settings you can try and make the wi-fi work properly.

Change the security type from WPA-WPA2  to just WPA.

Change the wireless mode from b/g/n  to b&g

If possible, change the frequency channel to fixed mode (say 7 or 11).

I have tried this and all of my wireless devices work as a charm. Hope this works for you too!

With a GT784WNV I would advise sticking with WPA2 and a fixed channel setting, along with B/G/N mode. But whatever works best!

Of course.

I recommend those settings both for stability and compatibility, with security being included into the mix. I forget if the GT784WNV has an option for only G and N devices, but that'd be the better option to select over B/G/N.

Do you know if the ActionTec model GT784WNV supports a wireless signal booster?
