Would this work? Wireless adapter + unmanaged router (ap) +network printer

Here are the equipments
1x belkin "tv" wireless adapter or just a wireless adapter with lan out
1 x wireless router (wndr3700 or dir625)
1x network printer

In have a spare wndr3700 and wanted to make it a repeater, which stock firmware do not support (have a ac66u as main). I try every custom firmware and the signal is significant weaker probably due to a bad batch.

I brought the adapter so I can make my printer wireless, I figure if it is possible to put the unmanaged router between the printer and adapter. Would the printer still get a unique ip so it is accessible?

 

You should be able to put the unmanaged router between the printer and adapter if you want, might be poor speed performance, just make sure the router is on bridge mode (unmanaged router).
If the repeater doesn't give decent performance, btw you should get about half bandwidth or even less as it has to split bandwidth between client and repeated router, (I have repeaters on a apple network and its super slow, good range but poor speed if that makes sense), your best bet is to get a cheap powerline and setup your spare router as a 'roaming network' just set the same network SSID and password. Setup the spare router to be in 'bridge mode'. You should get near full speed from your roaming network as well, and you can place it anywhere where you think signal could be boosted.

They are relatively cheap, £25 ~$40-50, I'd recommend getting a 500mbps ones to be future proof, as 200mbps ones are cheaper but the whole powerline network will downspeed to the slowest adapter so choose carefully.

 

Everything is set up and working as intended but one thing.

At the same location,
Using the adapter direct to computer can use up my internet bandwidth (speed test 20mbps ish)
Adapter to acesspoint to computer via lan (20mbps aswell)
But if i use wireless from the access point , it is much lower even I am just next to it.

Is this normal? Essentially there is no repeating function here, and main router and access point use different channel.

 

Sounds like poor performance on the wireless from the access point?
i assume it goes main router > LAN > access point > wireless > computer ? where you have poor performance on speed?

Check your link speed on windows (adapter properties I think its under it should show 54mbps or 72mbps or something higher hopefully?
