Hi all,

I recently recieved a firmware upgrade for my vr300 from like a week or two ago, I updated the firmware automatically via my wireless connection on laptop.

and since then I find unstable bandwidth speed with lag or slow performance in accessing the router gateway,

the DSL connection itself is stable and the ISP told me that the ground line speed is what it should to be and more actually, the router reads that the line has 40MB/s connection,

this problem happen many times through the day, I tested the bandwidth via many devices and it gives the same low performance.

while everytime it happen I open the gateway and find it slow performing with no obvious reason but I find the line speed itself stays stable at 40MB/s.

I need to know if the problem with that new firmware or if it with the modem router itself so I can return it to the warranty services.
