600. I'm pretty sure the 450 isn't dual band. If you have a connection that supports it and have high enough bandwidth, the dual band is best for Netflix on one and laptops on another.
Same situation here. The worst part is 2.4GHz band gives me about 20Mbps. This is the latest router I bought for my apartment (from Amazon) 29 days ago. The other one that I have for my home (from BestBuy) is about 6 months old and its is pretty good. I contacted Netgear. They initially agreed that the speed is lower, but later said even 20mbps is good enouht for HD streaming. I told them I have 4 4K tvs and want to stream 4K on all 4K tvs (LOL) I have asked for replacement from Amazon. I will update if the new one is any better. Its a same Netgear product sold by many stores. I wonder why prices are not same and whether the product is 100% same from store to store.
I don't think so for now because the AT&T doesn't release those kinds of deal.You have to use their own equipment if you are with at&t biz I was for 3 years before with at&t. Now I switch to Timewarner.
