Would a WiFi USB adapter be better than a PCI wireless card?

Hi all,

I already have the TL-WN851N 300Mbps Wireless N PCI Adapter but the antennas are attached at the back of the computer case.

Worse still, the case is huge (475x200x440 mm LxWxH) and the PCI wireless card antennas are right smack in the middle of the back of the case. The back of the case is facing a wall, and the internet speed is really slow (about 2Mbps from

I would like to ask if getting a WiFi USB adapter, such as the Aztech WL568USB or TP-Link TL-WN822N would help.

I currently own a Cisco Linksys E1000 router, and it's placement cannot be moved (as there is only one network point installed by my ISP), and the signal has to travel across 2 stories, and 2 walls.

Any advice would be greatly appreciated. Thanks!

    No, it won't help. USB adapters don't have the room for an antenna. That's why internal adapters are usually better to use, because their external antennae can pick up the signal better.

    If this is for a desktop, then you should look into 1 of the following solutions:
    -- installing a wireless bridge/booster in the house. Essentially, the bridge/booster unit will pick up the signal from the main router, & then rebroadcast it so that your PC gets a stronger signal. If your current router is 2 stories away from your PC, then you may want to put the booster halfway between the two.
    -- a better solution, especially for a desktop PC, is to have a cable installer run Ethernet cable from your router through the walls to the room where your desktop is. That way you're not as dependent upon the radio signal reception from the router.

    The big question, of course, is the ISP's network "node". Which ISP do you have: Comcast, Time Warner, Verizon FiOS? And how is their node connected to the router: standard cable-type access (coaxial cable to a cable modem, then Ethernet from the modem to the router), or fiber-type access (fiber optic cable to the house node, then Ethernet cable from the node to the router)? Again, the ISP might have had issues about where they were willing to install it (especially if it was Verizon FiOS service), but a 3rd-party cable installer can extend the cables so that your router can be in a more convenient spot for you; they could even install internal Ethernet cables that run back to wall jacks that they could install near the router, so that you could have multiple rooms wired up. The only downside is that, if something goes wrong with the 3rd-party wiring, the ISP won't send a repair tech out (or at least not without charging for it).
  2. I am from Singapore, and the ISPs are a little different here. The box has some kind of cable that supplies cable TV, it looks like one of the cables that hook up to a TV.

    Was wondering if getting a router with double antenna would work better, as my current router is without antennas. Or would a powerline adaptor system be better?
