Is repeating a better option than "MIMO"?

    I need to setup a wireless network where a few clients are in the next building from the wireless router. So I have two choices: use a WRT54G connected to the modem in one building and then put a WAP54G in the next building to repeat the signal OR just use a WRT54GX to boost the signal at the source? Obviously in my case, longer range and dead spots avoidance are more important than speed. So which option is better?

    If you use the WAP54G, as a repeater, you will halve the bandwidth of your connection. So if bandwidth is an issue. repeaters do not cut it. A typical 802.11G router will give you about 22mbs under the best of conidtions. The repeater will cut your maximum bandwidth to about 11mbs. Each client will cut you performance further. Two clients will get cut the bandwidth in halve again. The costs of a WAP54G is about $79.99. The problem with the WRT54GX is the costs of the router and the WPC54GX cards. The best you can get in terms of bandwidth with the WRT54GX is about 43mbs with a WPC54GX. The WRT54GX has much longer range, but costs about 179.99 on sale and the WPC54GX costs abut $99.99 per card on sale. The WPC54GX is a PCMCIA card and there is no PCI or USB version of it at this time. You can use a PCMCIA to PCI adapter with it, but drives up the cost about $30. If bandwidth is not a issue, I would use the WAP54G as a repeater. You can try to use the WAP54G as a bridge and use another WAP54G as an access point on a different channel and with a different SSID and may get better results. The two WAP54G units should be on channels at least five channels apart to eliminate any interference.

    The few clients on the other building, the one that does not contain the modem and router, only want to share the Internet not files. Therefore, reliable connection to the Net and longer range is more important not speed. With Internet, getting 500kbps should be good enough. Also, cost is not an issue here. My inclination is towards using a WRT54G connecting to the DSL modem in one building and having the signal repeated with a WAP54G on the next building. My rationale is repeating is better than having a "MIMO" wireless router because the "source" ie WAP54G is inside the second building and therefore, the signal is stronger as opposed to having just one WRT54GX that has not only to fight the tough external shell of two buildings but the 50 feet of space between the two structures. Has there any comparasion testing between using a WAP54G as a repeater and WRT54GX? Does using two WAP54Gs in bridge mode increase range as opposed to using a set of one WRT54G + WAP54G with the WAP54G in repeater mode?

    There is probably no difference between a WAP54G/WRT54G and a WRT54G/WRT54G in repeater mode. If you use the WAP54G as a bridge and connect another acces device to it you would get more bandwidth. The WRT54GX gets its maximum gains with the WPC54GX. You may not get too much penetation into the second structure with the WRT54GX, especially if there interior walls to go through. You should have the two devices in a line of sight and possibly and add access points by a wired connection, or have the access point connected to a WAP54G in the second structure mounted as high as possible. You can add directional antennas on your bridging devices. The antennas on the WRT54GX are not removable.

    I can use WRT54G/WRT54G in repeater mode using just the Linksys firmware? I always thought the WRT54G cannot be used to repeat the signal? That to repeat, I need the WAP54G? I don't see anywhere in the config for the WRT54G that says repeater mode or bridge mode for that matter.

    you are going to need 3rd party firmwar like dd-wrt or hyperwrt

    HyperWRT may not support client mode according to a post on their forum:
    http://www.hyperwrt.org/forum/viewtopic.php?id=66

    I am trying to do the same thing as others here and it would be worthwhile and very helpful if someone could create an FAQ or HOWTO on the topic.

    E.G. from another thread here:

    Unfortunately, "client mode" requires third-party software. I hope the "prefinal" dd-wrt works so I don't brick my WRT again.

    [gripe] All this stuff is _WAY_ more complicated than it should be if you don't want yet another technical hobbie that eats up hours of your time. I'm about two steps away from getting out the _really long drill bit_ and wrapping my house with CAT5 cable. Did that two houses ago, worked great. Maybe this house has too many nails or something. The same equipment in a previous 3-story house worked great from basement to 3rd floor. In this house I can't get a descent signal from one floor to the next--even after dropping more money on the Linksys hi-gain antennas. Argh! OK, I feel better now. Time to go waste some more time and money getting this wonderful wireless network working.... [/gripe]
