Mynet N750 suffering random huge latency over wifi

Hi

I have been using the N750 for 9 months and for last few weeks it has started developing huge latency over wifi going all the way upto 3000-7000 ms. Below is the spanshot of the ping status:

The latency issues starts surfacing when I do some heavy data exchange for an extended period of time. I tried changing the location of the router, sat next to it,  tried the 10 second reset to defaults etc but nothing seems to help. Is there something that I can try before I send it back for replacement.

Did you try contacting support to troubleshoot this issue?

Performance depends on factors including distance from the access point, volume of network traffic, building materials and construction, operating system used, configuration of wireless products used, interference and other adverse conditions.

For additional help with this issue feel free to contact one our support specialist.
