    I have my WiFi network running off a trendNet TW100-BFR114 i than have a 8-port PoE switch by Netgear and 8 TrendNet AP's.

    Every morning I come in the Wifi is not allowing internert connection , the connection is still established just limited to local.

    If I by pass the switch the same issue occurs with a wired connection to the router directly.

    I have metro-E service/VLAN from frontier communications so I have 2 ports set up each with their own public IP pointing to the internet and if I swap the ports around the same problem is still there, only the WiFi segment goes down.

    TredNet had me update the firmware but no help, I really feel its a bad router but to have 2 bad in row? well thats what TrendNet says they are suspicious of my other network devices (switch/modem)

    I replaced the router but the same issue still persists:(

    What do you guys think? and suggest I test to find out?.

    There may be a setting in the modem that shuts off Internet after a certain time period. Or a similar setting in the router.

    Are the computers left on? If so the network adaptor(s) might be power saver mode. Can do into Device Manager and disable that.

    I can come in with a laptop and connect to the wifi establish a connection,
    I just wont have internet. Thats pretty much all the WiFi is for, mobile users.
    They can get a new IP or repair their connection all day long they can patch right in the the switch(if they had access) which I do and have done to test, no insternet till that router is power cycled.

    Verify the mobile comps actually are getting an IP address from the router DHCP server. I fixed a network yesterday where the mobile comps were showing as connected to the AP but were not getting assigned IP addresses. They were getting the 169.x.x.x IPs by Windows.

    That model router is a real cheapo & I wouldn't trust it to handle a lan with more than 2 comps, yet alone multiple APs. In theory it should work, but remember, you get what you pay for. If you need 8 APs then you should invest in a real commercial router.

    How big a zone is the wifi? You could all but cover a square mile with 8 APs!

    If I had to use 8 APs I assign them all static IP addresses and disable their DHCP servers. The router would handle all DHCP assignments. I'd give each AP a unique SSID, thereby providing 8 possible connections. If these APs do not have built in support for point to point you MUST use unique SSIDs.

    You are not going to find a router that will handle that load for under a 150-200 bucks..

    The computers on the WiFi are not getting IPs from the routers DHCP they are getting the 169.x.x.x

    The building isn't a squar mile of course it only 40k-45k in squar feet. I had 4 AP's at first, same brand TrendNet really inexpensive, but there where many dark spots or no reception zones, so I put added one in each hall. AP mode, static IP's. I don't have separate SSID's however I will change that( and probably the router as well)... DHCP is disabled in the AP's there only in AP mode all the work is on the router, but let me ask you, " would running them in bridge mode or letting them do the IP assigning take the load off the router? ".

    Appreciate all your help-full knowledge,

    Bridge mode will lighten the load on the router IF the APs also do DHCP. However, the connection rate will drop about 50% for every node. For example, if a laptop connects to AP #6, and AP #6 connects to AP #3 and AP #3 to the router, the transfer rate will drop to about 10-15 mb/sec, probably less because the stated rates for wifi are theoretical only.

    If have 80211g APs and adapters, the stated rate is 54 mb/sec, but that will never occur in the real world, more likely the actual transfers will be about 30 mb/sec max. Reduce that by 50% for every connection between the router and the adapter.

    But I believe your actual problem comes from the fact that your APs are not using unique SSIDs. Give 'em all IDs like AP1, AP2. AP3, etc. Or by location: 1st-floor-hall, 2nd-floor-hall, 3rd-floor-hall, etc. Use names that will make it easier for you to t-shoot the wlan and that users will easily identify.

    Get the idea that a user with a laptop travels about the complex. If the APs all have the same name, his wifi connection manager will have 8 APs listed which all have the same name. How do you know which is which? (who wants to remember mac addresses?)

    Thanks for that info TonyT

    All the routers connect to the PoE switch independently , no daisy chaining
    i have not set them up as bridge yet cause of the holiday, I did see that they can be DHCP's.

    So with this new info you have armed me with I am going to fix this, I'm sure.

    -=Side Question=-
    is there equipment that allows roaming users to move from AP zone to AP zone while connecting automatically without service interruption as if it was all one big WiFi zone?

    I do not know if this has been answered
    Are you running DSL or cable based broadband internet
    On dsl settings there is a default setting of "connect only on activity" ( paraphrased)
    Change that to "always on "
    Its in the connection type settings
    You might try updating the firmware as well

    good luck

    Yes. You'd have to setup the APs in Bridged mode (Point to Multipoint). Not all APs have this capability though. Basically, you have a central wireless/router and the other APs are bridged to it. Thus, you have the same SSID, subnet and gateway for client computers no matter where they are inside the wlan's range, and the connection is seamless/always on.

    Thanks for that link
    However I am still confused;
    I had thought that AP mode was where the router did all the ip address via dhcp perhaps and the AP's where just a means to connect to that router(so even if there was many AP's to connect to you would be connecting to one network segment "same SSID, subnet and gatway ").
    I had thought that Bridge mode was going to make the AP's act like their own dhcp/router making a separate network, SSID and subnet for each AP in Brige mode.

    I ask this because I have them in AP mode. They all used to have the same SSID, but now there all on different SSID's, as you recomended, yet no mater what AP I connect to I will be on the WiFi nework same subnet and gateway.

    Oh... since setting seperate SSID's I have had no isues with th WiFi segment, has been running strong for the last 3 days..Thanks for the advice.

    If the base router is a wireless router, then yes, all the individual APs will be on the same subnet IF you set them up that way. Some APs have built in DHCP which can be enabled or disabled. I prefer top disable an AP's DHCP if the AP is connected to a router. I let the router handle all addressing. It makes it much easier to t-shoot and manage. If you have a router and APs connected to it, and each AP does its own DHCP, the result will be IP address conflicts on the network because AP1 may not "know" what the router addressing scheme is and may not be aware of AP2's addressing either.

    For example, I setup an wlan at a friend's house like this:

    Verizon FIOS modem/router/AP all-in-one unit:
    IP: 192.169.1.1
    subnet 255.255.255.0
    SSID: Bergnet1

    Netgear AP:
    disabled DHCP
    IP: 192.168.1.2
    subnet: 255.255.255.0
    Gateway IP: 192.168.1.1
    DNS: 192.168.1.1
    SSID: Bergnet2

    The AP was necessary because the FIOS unit is in an office at corner of a large house and the office has cinder block walls, so the FIOS AP has a low range. The Netgear AP extends the wlan to the rest of the house.

    BTW, glad all is running smooth now!

    8 AP's is a lot of WiFi without a controller.

    I have been looking at WiFi controllers i like how they improve seamless AP switching, a friend recommended the Cisco 2106 Wireless LAN Controller, but read that even though it has 8 ports it only supports 6 AP's and can only provide power to 2 AP's so I think that it only has 2 PoE ports.

    what would you recommend? Cisco is so pricey I feel

    -=I know this thread is solved so I hope I can still ask here. I will start a new thread if you feel I should.=-

    well I spoke too soon, my WiFi seg went down again so I went and bought a cisco E3000, and it has more trouble it seems. I put it in place of the junk router and it only last for about 25 min. I set up the lan and wan settings connected a laptop to the wifi, surfed a min and than bam no internet, but I notice that I am still on the right network I have the right subnet and ip scheam, all is good just no internet. I can not ping the gateway or AP well some times I get 75% loss or 50%, weired stuff like that.

    So I placed the old router back to see what I must have missed in the configuration, but it acts the same way. I released my ip and renewed, I get the ip address and subnet and gateway as it should be, but with out internet. If I reset or power the router its good, I can plug in to it and get internet. It seems to mess up whn I connect to the AP.

    What brand/type of modem is used for the metro service? I suspect that it is not playing well with the routers. Many modems have built in NAT and DHCP servers and if enabled will conflict with router NAT & DHCP. Double NATing really messes things up.

    I don't see any print or markings on the ISP's device, there looks like a spot it was removed, so I was going to call them and ask them what you asked.

    I went to work late today to find my boss using the WiFi, he said it worked when he got in, but it is intermittent some times the web page times out or is really slow to load. I have same results on my laptop.

    There was one thing I changed today. I was double checking the settings in the AP's and on the LAN settings I had them all set to their static IP and the subnet but the default gateway was 0.0.0.0 I changed it to the routers IP in all the AP's but nothing has change performance wise, is still intermittent or very slow to display a web page if at all.

    Do the AP's use bandwidth?
    Does the router for the WiFi network need to be a wireless router? or doesn't matter?
    I had a thought to bypass the router and program the AP's with the ISP's WAN settings?

    -Gringoyle

    -= Edit =-
    If i patch in the the switch on the WiFi network I have no issues its only on wireless I have the poor service. Could I be experiencing some impedance?
    But I still have haunting suspicion that tomorrow it will all be down again... even if I patch right in to the router
