WRT300N Secure (WEP) Access Point detected as unsecured - can't connect

|I'm using WRT300N (firmware version 1.03.6) router as my wireless network.  It's encrypted (WEP). Couple of of wireless computers (WIndows 2000 & WIndows XP,Sp2, using G adapters) can detect this wireless network correctly and connect to it. However, couple of my computers with Windows XP, SP2 media center 2002 are unable to detect the network correctly.  They detect the correct SSID network but always show it as "unsecured wireless network" whereas it is setup as Encrypted secured network (WEP).  So I can never connect to the network. When I power down my router, these computers then do not see the network, and when I repower the router, the network is detected again but not correctly as I mentioned above.
The connection setup is identical for the computers which connect correctly. I've reset the Router/modem, restarted the computers, redone the router setup again but no success. 
Any help will be greatly appreciated.
Thanks & Regards,
Irfan R

First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use.  Also, delete your current network (this will clear any old settings).  Reboot computer.  Return to "Preferred Networks".  Re-enter the info (SSID, encryption (if any), and key (if any) )  for your current network. Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".  Reboot computer.  You should connect automatically to your network.
If you still have trouble connecting, in the computer, temporarily turn off your software firewall, including Windows Firewall, and see if that helps.
Hope this helps.

  • WRT300N as an Access Point

    Hello,
    I own a Linksys WAG200G that is connected to the internet and to 2 computers, and I recently adquired a WRT300N router.
    Can I use my WRT300N as an access point that receves from my WAG200G (via wirelless).

    Actually firmware will not resolved the problem. That is the product limitation of the WAG and the 300n. You can purchase a WET54G, or 2 WAP54G.

  • Rogue Access Point Detected

    I am receiving "Rogue Access Point Detected" on some of my Cisco 1242 Autonomous AP's.  Is there anything I can do to understand if this is a real threat? How can I make any use of these alerts?

    Any access point that is not part of your WLC mobility group will show up as rogues. How you can make use of these reports is within WCS / NCS or the controller you can label the rogues as friendly's if you know about them. Lessens the alerts. You can also run a AP in rogue detector mode whereby allowing the system to determine if the rogue is on your wired.

  • RE: How to secure an access point signal.

    Hi everyone,
    I have difficulty making my access point wireless signal secure. My network setup is simple, Modem to Router to Homeplug 1st floor, (secure wireless signal),
    2nd floor (secure signal). Problem when comes to 3rd floor, signal too weak, so I place Homeplug to Access Point. (wireless works well but not secured).
    Tried calling D-link support but was told that I need to fix static IP address before things can work. What the **** is that? Was told many technical issue about sub-net different, etc. Lastly the setup disc don't work with a Mac. (HaHa).
    Thank you all in advance for the solution.

    How are you going to connect them?  cat5 or coax?
    cat5 instructions:
    Can I use my wireless or an extra router along with the Verizon provided router?

    Can I get an ethernet connection in a room with only coax?

  • Best way to setup WRT300N as an Access Point

    I have upgraded my wireless network to 802.11n by replacing my 802.11g AP and NICs in the kids computers with Linksys gear. My old wireless router was configured as an Access Point (no gateway functions). What's the best way to set the WRT300N like that?
    I have connected my wired LAN to one of the switch ports (not the WAN port), disabled DHCP, Firewall, & NAT. This seems to work but I'm not sure if it's the best way to do this. Performance seems a little slow.

    the way your network is setup right now is fine. However you say that you are facing speed issues.Is this on the wired or wireless ?
    Have you checked what firmware version your currently have on the router.Upgrade if necessary.

  • Cisco Security Advisory: Access Point Memory Exhaustion from ARP Attacks

    I recieved this Cisco Advisory e-mail today. I have 1200 access points that I upgraded yesterday to 12.3(7)JA2, in which this problem was corrected. In the advisory it states to upgrade to this software release and to make a configuration change on each radio interface. I made this change on Dot11Radio0 interface and it took. I have 2 more interfaces ( Dot11Radio0.2 and Dot11Radio0.75) in which I get an error when I try to make this configuration change. I don't quite understand these interfaces, so I would like to know if I really need to make this change on the other 2 interfaces or is making the change on the 1st one enough. Any information is certainly appreciated. Thanks, Laurie Coles

    Since you have subinterfaces configured, you are apparently using
    VLANs on your APs. The ARP table is only relevant for the VLAN
    with the management IF, that is the native VLAN.
    For all other VLANs it's simply bridging, therefore no ARP table,
    and therefore this vulnerability doesn't apply here.
    So your only concern should be the native VLAN, and unless you
    need wireless access for managing your APs the best way for
    securing this would be to not configure a SSID for this VLAN.
    Then the only access to the AP would be over the Ethernet-IF.
    The security advisory is more important for APs configured
    without VLANs where wireless clients and the management IF
    of the AP are in the same (W)LAN.

  • After I factory reset my Iphone 4s, I can't finish the step where it ask for WIFI Network, I guess it don't detect WIFI and can't connect to iTunes also. What should I do?

    I can't finish the step after I factory reset my iphone 4s because I can't get thru with the CHOOSE YOUR WIFI NETWORK

    If you can't see your WiFi then is your router broadcasting the SSID or do you not get to that point?

  • Can't access ITunes. Error message"Can't connect to iTunes store"

    Help!

    Try restarting and the iPhone.
    If that doesn't do it, one thing that others have done to fix this is manually set the time incorrectly (Settings > General > Date & Time), test again, and then set it back to the correct time.

  • Setting up a netgear n300 as wireless bridge/access point with airport extremee

    I just replaced my netgear wireless router with the airport to allow our many devices on the network without knocking each other off and also increase the speed.  But would like to use the netgear as a wireless bridge or access point so that I can still connect my NTFS formatted hard drive to be shared on the network.  Any suggestions would be appreciated.  I can not seem to find my netgear router with 192.168.1.1 as that comes up with another device.  I have tried doing this with a windows laptop in another room but can not seem to make it work.  I am now hooked up directly to the airport thinking i need to do it that way and still no luck. Please help.

    As long as you intend to do this over ethernet it will work.. you cannot easily wireless repeat or bridge to an apple router.. you would need specific hardware to do it.
    What is the exact model of netgear you have?
    The setup method depends on the functionality of the router.. but lets assume it does not have a bridge or WAP mode.
    You use WAN bypass.
    1. Setup the Netgear with IP address in the correct IP range for the rest of the network.. it is hard to talk generalities so lets say the apple is main router and your network is now 10.0.1.x .. then set the Netgear to 10.0.1.250 (apple uses IP 2-200 by default) you can use any value you like outside the DHCP range. Up to the limit which is 254 as long as you keep track of all static IP devices. Apply this setting and power cycle the router.. and you might need to power cycle the computer as well to pick up the new IP.
    2. Turn off the DHCP server in the Netgear. You may lose connection to the netgear now.. do not worry about it.. (this can be combined with one.. if you firstly turn off dhcp before you change the IP.. but whatever is possible.. at some point you will need to change around and if you forget what IP .. you will be in a mess.. so write it on a label and stick on the base of the router.. also without dhcp you will either need to reset router to factory using reset button or use static ip on the computer. )
    3. Plug ethernet from LAN of the main router to LAN of the Netgear. Reboot the whole network is often necessary.
    4. In your computer plugged somewhere in the network.. open browser and go to the address you set.. 10.0.1.250 in my example.
    5. You can then setup the Netgear to do whatever you like.. DIsk access is fine.. wireless is fine.. it just cannot be a router.
    Many many reboots if you get lost. Hit reset and start over.

  • Error when accessing a single Access Point

    Dear all,
    Since yesterday I can't access anymore my unprotected Wifi Access Point (receive an error message stating "an error occurred while trying to access selected..." or something equivalent).
    However another PC can connect to the access point, and my macbook can properly connect to a different access point.
    I already completely reset my access point, and I think that the underlying issue may be linked to the fact my macbook has cached the Access Point's mac address.
    Would you have any clue how to reset this cache or even better how to solve this issue ?
    Thanks a lot !
    Laurent

    In the Airport settings in the Network System Preference you can change the "By default, join" option to "Preferred networks". B doing this you will access to all of the networks that have been saved. Just delete any of the ones you need to, apply the change and then you can readd them.

  • Can an Aironet WiFi Access Point bridge multiple internal VLANs?

    I have Cisco Aironet 2700e access points.  Historically they were configured with a single SSID on both radios with WEP 128bit security.
    I now need to add new WiFi devices to the network that have limited flexibility.  They must be associated only with a specific radio (2.4ghz or 5ghz) and WPA2PSK security.
    My thought was to create two additional SSIDs on the 2700 access points, one for 2.4gz WPA2PSK and the other for 5ghz WPA2PSK.  The pre-existing SSID will continue to use 128bit WEP.  To do that  I need to use VLANs on the 2700e.
    I have no other VLANS on my network.  I only need VLANs on the 2700e because I have different physical devices that support different WiFi frequencies and security options.  I don't need to segment the network.
    How do I bridge the VLANs on the 2700e?
    Devices that connect to the non-native VLANs appear to be isolated from the rest of the network (as I would suspect with VLANs).  But that's not what I want .  I'm only using VLANs because I need multiple SSIDs, and I need multiple SSIDs because I have different physical devices that want different WiFI access point configurations.  I can't seem to find any way to configure the 2700e to bridge the VLANs for the multiple SSIDs.
    Any guidance would be appreciated.  I could buy additional access points but that seems to be defeating the purpose of having a device like the 2700e.
    Any help would be appreciated.
    Thank you.

    I made these changes to the example here:
    https://supportforums.cisco.com/document/55561/multiple-ssid-multiple-vlans-configuration-example-cisco-aironet-aps
    and it seems to be working.  (By "working" I mean that I can now ping to/from devices connected on different SSIDs.) I had to make these changes from the CLI.  There does not seem to be a way to make these changes from the GUI.  Is that correct? If there is a way to make these changes from the GUI please let me know.
    The changes I made were to make the sub interface for Dot11 radio 0 on the VLANs part of bridge-group 1.  So assuming the config in the example:
    ap(config)#interface Dot11Radio0.2
    ap(config-subif)#no bridge-group 2
    ap(config-subif)#bridge-group 1
    ap(config-subif)#exit
    ap(config)#interface Dot11Radio0.3
    ap(config-subif)#no bridge-group 3
    ap(config-subif)#bridge-group 1
    ap(config-subif)#exit
    I did not change the bridge group on the Ethernet interface.
    Questions:
    1. Did I create any new problems making this change? It seems to work, but am I going to get myself in trouble somewhere else?  Intuitively it makes sense to me: the VLANs are now part of the same bridge group (1, the native VLAN).  So all traffic should be bridged together.  Correct?
    2. I didn't change the Ethernet sub interfaces.  I don't seem to need to make that change.  I also don't like things sitting out there that I don't understand.  Should I do anything to clean up the Ethernet interfaces?
    3. The original configuration was made entirely from the GUI.  This change needs to be made from the CLI.  Can it be done from the GUI?  I can't seem to find a way to change bridge groups for a sub interface from the GUI. It worried me that it can't be done from the GUI.
    Thank you.

  • Mac-adress list of manufacturers only for access points

    hello,
    i'm going to look for forbidden access points at the ports of huge network. is there any document that can show me whether a mac adress is an access point or not ?

    If you want to do rogue access point detection then you have a few options:
    1. Scan suspected ranges for port 80 servers as almost every access point has web-based configuration.
    2. Cisco has provided a list of vendor mac address who make Access Points.

    Hi All
    I restarted the Access Point and will see what happens. Our Access Point and WLC are in the Same VLAN.
    WLC is connected to Layer3 switch and the port is configured as Trunk port with additional command switchport trunk native vlan 12.
    The access point ports configured are also configured as
    switchport mode trunk
    swichport trunk native vlan 12
    Are these configuration correct for controller and Access Point.

  • Bridge to bridge and bridge to access-point via wireless is it possible.

    here;s my topology i am trying to configure. i have a router whose ethernet is connected to a bridge.this bridge 1 is connected to a bridge 2 via wireless. now i am trying to connect a access-point via wireless to this bridge2. is it possible for bridge 2 to support connectivity to the bridge1 and the access-point both of them via wireless.
    can someone pls help me on this.
    waiting for someone to reply.
    regards
    sebastan

    You can set up each radio in the access point for different functionality. Considering the scenario, this can be done by setting up the SSID for the G radio and another SSID for the A radio. Then, set the role in the radio network parameter for the G radio to access point and for the A radio to the root bridge role.
    ou can prevent unauthorized users from reconfiguring your access point/bridge and viewing configuration information. Typically, you want network administrators to have access to the access point/bridge while you restrict access to users who connect through a terminal or workstation from within the local network.
    To prevent unauthorized access to your access point/bridge, you should configure one of these security features:
    Username and password pairs, which are locally stored on the access point/bridge. These pairs authenticate each user before that user can access the access point/bridge. You can also assign a specific privilege level (read only or read/write) to each username and password pair.
