Is my router affecting internet download speeds?

[patkim]

I have 512 kbps internet PPPoE connection and I have DIR 615 router that I have been happily using for past 4 years. Last few days I have a strange observation, with router connected (wired or WiFi) I get very poor download speeds hardly 200kbps whereas upload speeds are ok at 450 kbps. When I connect the ISP LAN cable directly to the PC (No router in picture) I get around 400 kbps download and 300 kbps upload.

I have checked with multiple speed test sites are results are more or less matching.

Is my router somehow reducing the download speeds and could there be a solution?
I have tried downgrading router firmware from last latest 5.13 to 5.10 as well but no effect. Thanks.

Check your SNR values

Where or how to view SNR value? It seems DIR 615 does not have this option.

go to 192.168.1.1 and use the user & password as admin.Then Status>Statistics

Under Statistics - It seems to be in the form of dropped packets, not an absolute number though.
Wireless - 124 packets dropped over 65K sent. 0 dropped over 46K received.
