I could do that if companies made the routers available for review AND if they have Ethernet WAN ports. I can't review routers with DSL, Fiber or Cable modem only WAN.
It's a fairly vertical niche - Premises Equipment - and even across different operators, there's a fair amount of custom work that is done per the operator's requirements - so testing a device from vendor X doesn't mean that it'll perform the same, or have the same feature set even from Operator C vs. Operator V as an example.
Tribal knowledge suggests that all Premises Equipment is inferior and less flexible that off the shelf -
Problem is that tribal knowledge is sometimes out of date - the latest crop of CPE I've seen from the operators is much better than what we saw even 18 months ago... I think much of this is due to a number of factors
1) technology pace - we're seeing AC1900 class CPE finally in the the sector, while it's been on store shelves for much longer - it's the requirements development and testing that takes the long time
2) services - the operators are rolling more and more over IP, so the CPE has to be more robust in the first place
3) Customer Demand - plainly put, customers are asking for more, and using it more
While it would be interesting to see something from a provider on the test bench, I'm thinking not much value if it could be tested, because it would only be representative for that particular operators configuration.
