I´m trying to find the best configuration to improve the roaming in a WLC 7.3I changed the power threshold under the TPC to -67 and in the client roaming I put in custom mode and the minimun RSSI in -78 dBm.but I was wondering if there is a specific configuration to improve the roaming.
View 3 RepliesIs there any additional configuration to be done on the 5508 WLC for Wireless Laptop / Voice Roaming? I tested with Wireless IP Phone and found some blankness in voice , whereas i have other access point nearby , which wasn't switching over easily .

We all use laptops and 2 xboxs' but sometimes the connection will dip, not often but sometimes. Do you think this is my wireless adapter in my laptop or because of the use of modems to open up a wireless network?I was thinking about buying a router and just connecting it to the modem to maybe improve the connection. Suggestions? I really do not know the configuration my dad did for this network, the only thing I know is he uses modems not routers which is pretty strange.

View 2 Replies View RelatedI have a two story house with a basement. Right now I have a Cisco Linksys E4200 router on the second floor in one of the bedrooms. I have a DLink GamerLouge 4500 in the basement. Both systems have the same SSID and are running on different channels. Computers connect to the appropriate one automatically. At least assuming that's what's happening.I am getting limited connectivity on the first floor in the kitchen and family room. Dining room, right by the second floor stairs is fine. All the bathrooms are dead zones. Note I have thick travertine tiles on the walls in the bathrooms so may inhibit signals. Trying to figure out the optimal solution for getting the house setup so everywhere has at least decent signals. I have alot of iPad and laptop devices floating around the house so wireless is key. Note I have wired plugs with Cat5e all over the house to a central hub in the basement which is where the DLink router sits. Thoughts on how to improve my signal strength? Especially in the farther reaching bedrooms and the first floor

View 2 Replies View RelatedCurrently I'm using one e4200 (v1) as my main router in the house. The wireless coverage downstairs is perfect, but upstairs the signal is weak. To improve this I thought about adding the WAP610N as an access point to my network. But this device gets quite some negative reviews ... Thus I was thinking why not add another e4200 (v2) to my network? The price difference is not that big, especially compared to other simultaneous dual band access points. So my question is, would following scenario work?
- first e4200, connected to my ISP, acting as a router, using both the 2.4 as 5 ghz band (basically my current situation)
- second e4200, connected (via UTP cable) to the first e4200, in bridge mode
- second e4200 also using both 2.4 and 5 ghz band, using the same SSID, security etc but a different channel
So when moving a laptop for example from downstairs to upstairs, automatically the router/access point with the strongest signal would be used.
I'm using a wireless g router (f5d7230-4) which for most purposes is fine? Specifically: 1. I can't seem to stream media content from my windows 7 pc to my lg tv (model 55 lw 6500), and wonder if the age of the router is part of the problem; 2. some iptv channels on my ps3 are slow to load menus, though programs run fine when I push play (I gather ps3 is restricted to wireless g but if I upgraded the router I would plug in the ps3 using cat6). When I speed test my internet connection I'll typically get results around 2.5-5 Mbps. I'm impressed that a router of this age performs so well it isn't obvious to me that upgrading will improve the setup.
View 1 Replies View RelatedI have configured a new LinkSys e3000 as as wireless router in our house.I have left the configuration as default (only secured it and turned on the DHCP server).I have only turned on the 2,4 GHz network ( because the 5GH had an even shorter range).Everything works and all my devices can connect to the router and access the internet.However i find the signal strenght of the router to be very poor.Already in the next room it drops to 60%. And in some rooms on the 1st floor the signal drops completly.This happens not even 20m away from the router in an ordinary "family house".Is there a setting somewhere which could increase the signal strength ?I noticed that the router has no antenna, can one be bought and attached so the signal increases ?The firmware version is 1.0.02 and i found a newer on your web 1.0.03.

View 6 Replies View RelatedI've got a WPA wireless network set up that utilizes a total of 4 WRT54GL routers as access points (on channels 1, 6, and 11 [the two APs furthest from each other both utilize 11). Each AP generally supports about 5 clients at a time (though sometimes as high as 10).Generally, everything is working, but the clients furthest from the access points occasionally lose their connections, and some users have reported periods when they are completely unable to obtain an IP. I am virtually certain that this is based on poor signal strength resulting from distance from the APs and/or RF interference from other APs in the building. I have done everything possible to improve signal strength by router placement, optimizing channel usage based upon RF surveys, and upgrading to high-gain omnis.
This leaves nothing to do apart from tweaking the advanced wireless settings to marginally improve problems related to weak signal and/or RF interference, so I've been reading everything I can find on these boards and elsewhere about changing Fragmentation Threshold, RTS threshold, and beacon interval. However, I'm left with the following questions.
1) There seems to be disagreement about Fragmentation threshold and RTS threshold settings. Some (including the Linksys Technical Troubleshooting Wizard) recommend that both be set to 2304. I have also seen people insist that Fragmentation be set to 2306 and RTS to 2304. A few recommend 2306 for both thresholds, and some advise 2306 for Fragmentation and 2307 for RTS (though by my limited understanding, it simply disables RTS when the value is higher than the fragmentation threshold value). Which of these settings is best? And more importantly, WHY is it the best? Generally, I understand what the settings do, but I am reluctant to change them when there doesn't seem to be a consensus about exactly what they should be.
2) With respect to beacon interval, I've seen both 75ms and 50ms recommmended to replace the default of 100ms. For a network of my size (4 APs, averaging 5 users each), will increasing the number of beacons (and hence the RF traffic even when the network is idle) pose a problem? Also, I'm a little less clear as to how this would improve connectivity.
Since these settings will affect all users, I want to make sure that I'm using settings that will be beneficial on the whole. The last thing I want to do is inadvertantly make things worse, and since I can't test things directly from the standpoint of each user.
I am trying to improve the coverage of my home network.I have Fios, and with the existing Wireless capabilities, there are several dead and low coverage areas in my house. This is due to a combination of where my router is (Limited by input feed) and the confuration of the house.
I have CAT-5 running to most rooms, so adding wired devices is not an issue. I went out and picked up an EA4500 router, and my plan was to convert my Fios Router to a bridge and use the EA4500 as the DHCP server. However, even with this router, my coverage is not improved. My preferred solution will be to get 1 or 2 additional access points that I can plug into my wired network, however, I would want to have a common SSID for the entire network.
I've recently acquired a Linksys E1200 router--which is more than a week old--from the recommendation of a friend of mine. The service is great and all, but the one thing that frequently bothers me is the seeming constant instability of my router's model. There are moments when the router performs smoothly, but there is as much an instance because the router doesn't seem to work at all even when the lights (and the accompanying connection) on my modem seem to be working in good order.
I know that a router will always have its problems, but this is really a constant problem with the E1200; and if so, if there's any way possible on how I can be able to "stabilize" the said router's performance.
I have 5 access points (WAP4410N) all connected to a befsr41 8 port/switch router, each AP has it's own SSID. Is it possible to to have one SSID for the entire wireless network so users do not have to change SSID's every time they change locations?

I have 3 Cisco 1242 WAPs that I have deployed at a site that has NO RADIUS/AAA devices. I have given all of them a different channel (1,6,11), but the same SSID and crypto (WPA2-PSK). The issue is when a machine boots up it associates with the closest/strongest AP, but as the device "roams" it does not which to a different AP. It stays associated with the original AP until that signal is gone. Then it quickly associates with the closest AP with no problem.
How do I get the device to associate with the strongest WAP? I have research "fast roaming and WDS" but it seems like you need EAP/LEAP and they do NOT have that at all.

View 1 Replies View RelatedI am having some troubles with client roaming on a 5508 controller running firmware 7.3.101.0. As soon as a client roams outside the range of an AP they lose data flow and do not seem to transition to another AP for about 1 minute.This is a small network with 6 x AIRCAP3502E-N-K9 AP's (running in H-REAP mode) on the same floor and clients are a mix of HP notebooks, Mac Books, iMacs, iPads and iPhones. There are several seperate SSID's setup and the problem occurs on all. All are WPA2/AES with either a PSK or 802.1X. Both 2.4GHz and 5GHz radios are enabled with auto power and channel selection.

Under the section intra controller roaming, WLC 7.0 config guide states that " When the wireless client moves its association from one access point to another, the controller simply updates the client database with the newly associated access point. If necessary, new security context and associations are established as well" URL.Within the phrase "If necessary, new security context and associations are established as well" . What is meant by the new security context ? My understanding is that only an update to the MSCB (with the AP info) is the only requirement as the client is within the same controller and subnet.I just can't think why would the security info needs to be updated.

View 3 Replies View RelatedI have two 5508, no anchor, only one SSID with internal web authentication using radius server.Under "Configuring Mobility Groups", Cisco guide says: "If a client roams in web authentication state, the client is considered as a new client on another controller instead of considering it as a mobile client".
I understand that if a client that has already autheticated via web roams between two LAPs that are associated with different WLCs, it has to reathenticate.
I'm looking to deploy a 2504 controller and some AP1142s but would like to provide the client with an alternative, lower initial-cost option in my proposal. I've been researching the AP541N access points but several areas of their implementation seem unclear to me.
Clustering: For the clustering feature is it necessary for the network to have other SBCS components (500 series platforms)? All of their other features are either unapplicable to or already implemented in the network in question; if I have to add another appliance I would rather go the LWAPP route and use a true WLC.
What are the cababilities of clustering? Can I implement some form of wireless resilience by spacing APs closer together than necessary and they will lower transmit dBm and intelligently respond to attempt to cover a new cell where an AP has gone down?
What about roaming? I believe Cisco advertises this as part of a small business voice solution. A client roaming between two access points in the same mobility group (cluster?) on a wireless voip phone should be able to keep connection, as it's analogus to some critical UDP communications that are going to take place on the clients.
I am running a WiFi network built on Cisco 1262 APs and Cisco WLC 5508. My APs broadcast two SSIDs, let call them "WiFi_Pay" and "WiFi_Free". I have a problem: when users migrate from "WiFi_Pay" to "WiFi_Free" (not moving, connecting to the same AP), the connection fails. If they try for second time, it is always successful. My task is to ensure that such migrations run smoothly and be successful from the first attempt.

What i want to do is connect these APs and broadcast the same SSID (e.g Aironet and NOT Aironet1,Aironet2..etc). Doing that, a user with a laptop can roam between these APs and won't have to re-enter the password of the SSID every time he changes AP. I would also like the encryption to be with a 128bit password key. From what i have read, i need a local authenticator to do what (Something called Local Radius Server).

Setting up a multi floor WLAN using a 6500 WISM Controller. Each floor has an AP group with the floor WAPs assigned. Each floor has a VLAN and the WLC has an interface configured. Each floor has a WLAN configured with the same SSID and the only change is the interface on the WLAN per floor.DHCP is remote on AD servers and each floor as a scope configured.Each floor works fine - we can get connected and get assigned to correct IP address. The issue we had with this setup was moving between floors. When we move up a floor the client loses connection to the inital floor (coverage - as expected). if we disconnect and reconnect it connects to the new floor SSID and gets an IP from DHCP.When looking into this - I then created an interface group and added all the floor interfaces into the group. I then applied the interface group to each floor WLAN and did soem testing - it worked as expected. I could now move between floors.The issue with this is though. When I was testing I already had an IP address assigned from DHCP - before I changed to interface groups. The issue is that the intial DHCP assignment no longer works and we cant connect to the WLAN anymore,
