Thank you for suggesting an alternative solution but this sounds too complicated and risky to me especially have to touch the firmware. I am also not familiar with Vlan setting. I will try to figure out why the connection via Linksys WRT310N wifi router is so much slower than via fixed line. I will deploy the 2 wifi router+switch solution which I can understand. I learnt that Linksys WRT310N has been superceded by WRT320N. Anyone has experience with this model to share or can recommend other reliable brand and model suitable for a small network?

There is no need to physically separate the networks. You just need to create two vlan's using 802.1q tagging.

The 310N is capable of doing this, but you may need to put openwrt (http://openwrt.org) firmware on.

Essentially you will have

<Internet>-Cisco:877:Vlan:0001 & Vlan:0002

Attach tagged Vlan0001 port to your existing wireless, and Tagged vlan port 0002 to your new wireless.

Alternatively you don't even need to buy any additional hardware. You can have multiple essid's off the Linksys, and send the tagged vlans to the linksys, and then seperate them out.

    Dear experts,

    Currently my office LAN setup is one common network for both
    office staff and the PCs in Computer Lab. We also have a Linksys
    WRT310N wireless router which is only for staff but we want to
    install another wireless router for students. The broadband is
    provided by M1 Connect (originally by Qala which was acquired by
    M1 last year) with 2MBPS fix IP with CISCO 877 router with ADSL
    function. I would like to re-configure the LAN to separate into 2
    sub-nets such that the staff's sub-net is better protected from
    potential access by students or visitors. Can any experienced
    network experts provide some advice? Thank you very much.

    Yours sincerely,
    H. E. Lim
