Netgear N300 router. No internet in the house. Can i still use the router in bridge mode?

> Netgear N300 router. [...]

   "N300" is a speed, not a model number.  Look for "Model" on the
product label.  Firmware version?

> [...] No internet in the house. [...]

   Ok.

> [...] Can i still use the router in bridge mode?

   To do what, exactly?  "bridge mode" is a widely misunderstood/misused
term.  What, exactly, does "bridge mode" mean to you in this context?

   General advice: You might have more success if you described the
actual problem which you are trying to solve, rather than asking how to
implement some particular "solution" ("use the router in bridge mode")
which may have little or nothing to do with the actual problem (whatever
it might be).

   Is this query related in some way to the folowing one?:

At least one of us is confused.
