I have ethernet connection and its connected to a router and then to my computer using the LAN port of the router . Everything is fine but the router is kept on another floor and thus , I cannot use wifi on other devices as I get very weak signal . So , my question is that if I buy another router and connect it with my first router and finally connect my computer with the second router , will this affect my internet speed ?
Networking – Will the internet speed decrease if I connect two routers together

It should work just fine -- as I understand it, you have a main router which your wireless routers are plugged into, and various equipment plugged into each router.
Since your laptop (or PC with wireless NIC) can only be connected to one wireless network at a time, it doesn't really matter too much how you set up the IP addresses.
One COMPLETELY OPTIONAL suggestion I have for you to make things work even more smoothly though is to configure ONLY your main router to serve DHCP and set up your wireless routers to not do this (if your wireless routers don't support passing IP traffic through from the WAN port without NAT, then you should at least be able to disable the DHCP server options and just not use the "WAN" ports at all -- instead of connecting the main router to the WAN ports just plug it into the regular LAN ports of the wireless routers that have DHCP disabled). This way, you have only one DHCP server managing all your IP addresses, and when you switch to a different wireless router your wireless devices keep the same IPs.
Ok, so I am finally answering my own question here. The answer is derived from the comments by Max Ried and James Womack. I wouldn't have figured it out on my own. In fact, my original setup was 100% correct. The problem was that Unit B (Huawei HG533) has a bug that does not allow clients connected to it to use external DHCP server. The only change I made was setting static IPs and now everything works.
So what I did was:
I set address of Unit A (D-Link modem + router) to 192.168.1.2 and connected it to the phoneline.
I have connected powerline adapter to one of the LAN ports of Unit A and plugged it into the mains
On the top floor of the apartment I have plugged another powerline adapter into the mains and connected it to one of the LAN ports of Unit B. I have figured out that it does not make any difference if I connect it to one of LAN ports or to the one labeled as "Fiber" - result is the same
I have disabled WiFi in unit A and enabled WiFi in unit B
I now connect to unit B and I have access to NAS, connected to unit B and to the internet available through Unit A.
However: I did not manage to setup DHCP. This seems to be the problem that initially did not allow me to create desired setup. I am currently using static IP address for both Unit A, Unit B and all clients connected to Unit B.
There is a setting called "DHCP transparent transparrent transmission" and another one called "DHCP relay" - both have no effect. I have tried enabling DHCP for Unit A and dissabling it for Unit B and putting it into Bridge mode with Transparent DHCP transmission no effect.
Quick search on the internet showed that this is a feature of Huawei HG533 and it seems like no one can get it to transmit DHCP transparently from LAN.
Anyway, I am happy with my current setup even though it is static IP. I am planning to replace unit B (Huawei HG533) with Asus RT-N16 running openWrt soon anyway.
Thanks to everyone who helped me to sort this out.
UPDATE: here are screenshots from the interface of Unit B (Huawei)

If the two routers are connected through cable the answer is almost no (you pay a little overhead).
But you don't need another router, an access point (or a repeater) is a better choice.
Note: you must choose a different non-overlapping wireless channel for the 2nd router. http://en.wikipedia.org/wiki/List_of_WLAN_channels
