Routing traffic on LAN via WIFI but send data over ethernet cable
Okay, so I'm not a networking pro.
We've got a beautiful wifi system at home. I'm living upstairs and the wifi/modem(aka superhub at virginmedia http://help.virginmedia.com/system/selfservice.controller?CMD=VIEW_ARTICLE&ARTICLE_ID=3859&CURRENT_CMD=SEARCH&CONFIGURATION=1001&PARTITION_ID=1&USERTYPE=1&LANGUAGE=en&COUNTY=us&VM_CUSTOMER_TYPE=Cable) is downstairs.
My LAN/WLAN signal and bandwidth is insanely weak and slow.
Not sure if it would be possible to establish a wired connection between my laptop and my raspberry pi via an cat5e ethernet cable.
Both of them are on the same subnet(192.168.0.1/24), same SSID.
But by default all traffic is sent over wifi. This is stupid, but I've tried connecting them via the ethernet cable and that does nothing. I assume I'd need a router.
Some time ago, I tried putting up my router and connect both of them to the same router(this router is entirely separate from the superhub provided by virginmedia, this is my own).
The problem is if I do this, neither my laptop or the rpi has internet. I can't get my router to get internet from the superhub over wifi(ie is the router being in my room and not downstairs connected to the superhub with an eth cable), so I can't use or don't know how to use it properly.
This is really basic stuff and like I said, I know next to nothing about networking.
Iperf is showing an average of 4MBit/sec bandwidth speed between my pi and laptop, despite being 15 CM away.
My router is an old Belkin router http://www.pcwintech.com/screenshots-belkin-f5d7234-4-v3-belkin-firmware.
