Multiple access points to flood an area.

From: windsurferLA on 23 Apr 2008 15:23 Multiple access points to flood an area. My attempts to provide reliable wireless access to guest laptop computers over an area spanning about 100 feet have proved unsuccessful. I suspect the problem is interference from numerous other wireless devices in the area. A possible solution would be to position two separate wireless routers (access points) toward the edges of the area with each wireless router (access points) hardwire linked to the modem via (possibly an Ethernet switch and) CAT5 cable. My current wireless router / access point of choice is the D-Link DI-524. It has been chosen because the native IP range 192.168.0.X of the D-Link does not overlap the 192.168.1.X IP address range of the router built into the 2WIRE2701 modem (wireless option disabled). My guess is that I can either: (1) configure each D-Link wireless router so they have non-overlapping IP address ranges and feed them in parallel from a switch, or (2) disable the DHCP in one of the units, and feed it (the second in the chain) from the first unit. Will either of these schemes work? How do I best configure the D-Link DI-524 devices so they act in parallel to flood the area with signal? WindsurferLA

But without describing where you're trying to do this it's impossible to say. If you have any control over the other devices it might be possible to reduce the amount of interference. But if they're not yours and you can't contact who's running them then it may not be possible to do what you're after. Rather it might be possible, but perhaps only with more access points, each running at a lower power. Likewise if the interferring systems don't need to be covering such a wide area it may be advantageous for THEM to reduce their own radio power levels. > A possible solution would be to position two separate wireless routers > (access points) toward the edges of the area with each wireless router > (access points) hardwire linked to the modem via (possibly an Ethernet > switch and) CAT5 cable. Without better info it's impossible to say if that's right or not. But yes, in general, you put an access point where you want coverage and run wire back to the switch. > My current wireless router / access point of choice is the D-Link DI-524. > It has been chosen because the native IP range 192.168.0.X of the D-Link > does not overlap the 192.168.1.X IP address range of the router built into > the 2WIRE2701 modem (wireless option disabled) All devices of this sort have configurable options for their IP address and/or IP range. Chosing one based on that is like chosing a green car because you think it's faster than a blue one (everyone knows red is faster anyway.

Use one as a router, use the other as an access point. They can be on the same subnet, just make one of the run DHCP and disable it on the other. DHCP requests will be passed through one to the other via the wired ethernet connection. An access point is basically 'dumb' in that all it does is pass traffic from the wired network to/from the wireless clients connecting to it.

How do I best configure the D-Link > DI-524 devices so they act in parallel to flood the area with signal? as the other reply has indicated.... we really need more details. You seem to mixing lots of different technical topics, but at the same time, don't really have a handle on technology. The entire paragraph on router "native IP range" tends to magnify that. SO - what is the real situation, and the area you are trying to cover ? Wait - 100ft ??? Are you kidding ? A single AP will do that - it's like 3 houses ? I can see my AP from up and down the block in all directions, along with several neighbors.... What is the Internet connection available to you ? Is it just a simple DSL line via your 2WIRE2701 modem ? Where will the AP's be located ? How powered ? and how connected back to your DSL modem or main router ?

It looks like I've found some real experts. The area I'm trying to cover is the top floor of an apartment house occupied by ten friends and potentially ten lap top computers. The building is 100 feet from front to back and 30 feet wide. The building is in an area with lots and lots of students, many of who have their own wireless access points. A check of networks in range will usually turn up at least ten networks and often many more. I really don't know who those other user are let alone being able to coordinate channel selection and power settings with them. The users on the top floor have a variety of laptop computers, none of which are set up to use MIMO or any of the proprietary range extension techniques. Currently, there is one wireless router located in the center of the top floor; it is set for maximum power on the least used channel. Although the current router and others that we have tried claim to deliver range to 100 feet, reception beyond 30 feet is marginal (one bar) to useless, especially at night when many others seem to power up their computers and wireless equipment. A directional antenna advertised as providing 10 db of gain did not seem to help significantly independent of its positioning. (It was a pole antenna that supposedly achieved its gain by flattening the radiation pattern.) It seems to be possible to get reception through two walls, but any more that that and reception is unacceptable. Each user wants to be able to connect from his/her desk and not relocate to the kitchen counter because of its closer position to the central source. I'm aware that the you can change the IP address ranges on most all routers, but having units whose default states don't conflict makes network repair easier; it is one less thing to have to reset when something goes wrong. The Internet feed is a simple DSL line via the 2WIRE2701 modem. The thought is to disable the wireless capability of the 2WIRE2701 (there is a control panel option for switching it off) and connect one of the four RJ45 Ethernet ports on the 2WIRE2701 to each of the two D-Link DI-524 wireless access points via a physical CAT5 Ethernet cable. Each D-Link DI-524 would be powered form a local source. Each would be located near the opposite ends of the building. I'm plan again to try the tandem configuration recommended by Bill Kearney in his post wherein the DHCP is disabled on the second-in-line router.
From: windsurferLA on 24 Apr 2008 00:06 Bill ... Thanks for prompt reply. Your suggestion makes sense. I'm going to give your tandum feed configuration a try. It is going to be a few days before my second DI-524 arrives and I have the opportunity to lash it up. see reply to ps56k's posting for my more detailed explanation. WindsurferLA.
