I currently have an obsolete WiFi G USB card on my desktop PC. And my desktop only has 100 Mbps Ethernet.
I also have my brother's laptop which contains Atheros AR5B93 WiFi module which has a/b/g/n specs (n could be draft2) . The laptop has Gigabit Ethernet.
Then I have an ADSL (modem+router) which has WiFi a/b/g/n support. The wireless speed is labelled as 150Mbps and it is not having any antenna. And it has 100Mbps Ethernet ports.
Now, I wish I could have fast file transfers between the PC and laptop. My desktop has obsolete hardware which limits the file transfer speed. I have checked the WiFi link speed between laptop and router is 300Mbps , even though my router is labelled 150Mbps. And i have checked file transfers between PC and laptop (with PC connected to router via LAN @100Mbps and laptop connected to routers WiFi access point @300Mbps) and the transfer speed remains at 10-12MBPS. I think the 100Mbps LAN is the bottleneck here.
As I need faster file transfers, I have the following options.
- Buy a WiFi N card or usb adapter for PC.
- Get rid of WiFi and Buy a Gigabit LAN card and a Gigabit Switch.
- Buy a Gigabit switch with inbuilt Wireless N router and a Gigabit LAN card.
Option 1 is cheap solution. But how great the transfer speeds will be? Will i get around 20-30 MBPS . Option 2 is good if i ditch WiFi . But in case if i use WiFi between laptop and router ( and of course LAN between router and switch) I will be limited to 100Mbps I guess. Isn't it?
Option 3 seems perfect but it is more expensive.
What do you suggest? And if I have to buy WiFi card for PC i will choose between one of these
-- TP-LINK TL-WN781ND 150Mbps Wireless PCI Express Network Nic (labelled as 150 Mbps)
-- iBall 300M iB-WUA300N Wireless-N Black USB Adapter (labelled as 300Mbps)
Please give your opinions.
