Netgear has set up a community forum specifically for General Router products. Most of the people who watch that forum are more likely to have experience with older routers and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

Thank you

What model do you have? 

there's an R6250 and a C6250.

the R series can be updated by the end user. 

The C series, the firmware is part of the partitioning from the ISP. 

So its kind of key to know what version you have to see if you can update.
