My client cannot communicate between each other, why ?
Controller: AIR-WLC4402-25-K9
AP: AIR-LAP1252AG-A-K9
I have two wlc 4402 to control 50 AP 1131. 2 WLC: wlc-01 and wlc-02, wlc-02 config as backup wlc in the same mobility group. Client authentication:EAP with Microsoft IAS/AD.All AP have joined wlc-01. Wireless client work well with wlc-01.For testing I config access point AP01 have primary wlc: wlc-01, secondary: wlc-02 If I change config of AP01 like this: primary wlc: wlc-02, secondary: wlc-01. Client is hard to connect to wlc-02 and it only connect when client set static ip ALL wlc run this softwar image: 7-0-98-0 Should I send wlc-02 to warranty service?

Previously the wireless networks works fine but for two weeks now most of the clients experiencing reauthentication frequently, Some experience it every 5 mins even if they are browsing or idle and not moving. I've check the session time out settings in the wlc and it was configured for 30 mins as default. I have around 900 student clients connecting every day.

View 4 Replies View Relatedi have a question about tunneling a software EasyVPN client to a client ASA Network. It looks like this:
EasyVPN Server 192.168.202.0/24 Network extension mode to Client EasyVPN ASA 192.168.1.0/24 This works fine in both directions. But now i want to connect the client ASA network via EasyVPN software client from outside. The user are already able to connect to the ASA Server on its static outside IP obtaining an IP from a 192.168.21.0/24 pool. This works fine. But how am i able to connect to the 192.168.1.0/24 network from this client?
I am preparing for CCNA exam and for that I have been working with OSPF in packet tracer.In the scenario below I have made configuration with three routers and everything seems to be working well. However, following ping commands cannot be reached.PC0 cannot communicate with other two PCs. Others can.(can ping from PC1 to PC0 and PC2. Can ping from PC2 to PC0 and PC1 BUT CANNOT PING FROM PC0 TO PC1 and PC2) [code]

Sometimes I cannot connect to internet due to "unidentified network" buy i can resolve this problem by restarting my modem + switch.
I tested ospf multi-areas in packet tracer as shown in attached file.(Sorry I don't know how to upload the lab image.)There I got a problem that router 0 in area 1 and router 6 in area 3 cannot communicate.Except this, router 0 can communicate with other routers and the same to router 6. I have made a virtual link between backbone,area 1 and 2 ABR router 1 and area 2,3 ABR router 4.I use process id 123 for every area. But when I type "show ip route" in router 0, it is shown [code] when it is typed in router 6, it is shown [code] So, router 6 cannot communicate with router 0.I don't wanna make a static route to 1.0.0.0 network in router 6.

View 1 Replies View RelatedMy friend and I bought Acer Aspire 5741's about 9 months ago and neither of us has had any problems until now. My friend went to connect to the internet via wireless router yesterday to find that there was limited connectivity (no internet access). We assumed it was a router issue and I gave her a number of things to check but all seemed ok with it. I went to her house to look at it today and when I ran the connection troubleshooter got "windows can't communicate with.......... (DNS server)". I connected my laptop via her router and everything was fine. I brought her laptop back to my house and tried to connect to the internet via my router and got exactly the same 'DNS' message - my laptop again connected without any problem.
I have re-booted the routers, laptops, network adapters etc and also checked the wireless adapter settings on both laptops, which appear to be the same. I have re-set the TCP/IP stack and have also tried ipconfig /release and /renew - none of which seems to have made any difference. the results of the tests are as follows (linksys is the SSID in use):

However, there is only a "local connection" on my mom's laptop, a Toshiba Satellite running Vista. Diagnosis: Cannot Communicate with Primary DNS Server (68.105.28.12). I've read a bunch of other posts on many websites but so far nothing has worked.

I have two routers in my office, each one having wireless extensions and its own DSL connection.I want machine on A subnet communicate with machine on B,I'll need some sort of physical connection (a cable? a new device?).Router A and B are typical home router with wifi extension: they only have a WAN port,I won't be able to let them talk to each other simpy by plugging an Ethernet cable between two LAN ports, since the two routers are on different subnets.

Problem: No internet connection. 'Can't communicate with primary DNS server'Information: I am using a Windows 7 64 laptop (LAN connection) to connect to the internet. Two days ago this stopped working (after working fine for 3 months). Using windows troubleshoot I receive the message 'Can't communicate with primary DNS server'. I have checked the IPv4 and IPv6 and they are all set to automatic.I then tried to reset this using Microsoft 'fix it solution' as indicated Can't communicate with Primary DNS Server this still had no luck.I have also tried,
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
and ipconfig/ release and ipconfig/ renew none of this has made any difference. I can successfully ping the default gateway but cannot ping google. All packets time out.Additional information: Using an older laptop I am able to successfully connect to the internet on the same line. Also the laptop that is not working does work fine at work. So I don't even know if the problem is with the hub or the laptop.
My wireless connection showed connected but Internet Explorer kept showing the page cannot be displaced. When I clicked the diagnose connection problems, the message kept coming back with "Cannot communicate with primary DNS server (65.32.5.111)".

It will connect to our home network (virgin media cable broadband) locally but won't connect to the internet. I've tried a few of the fixes I've read on here such as changing the DNS settings myself but it's going nowhere.I can connect to other networks for example my parents virgin media network and the other laptops and my ps3 can all connect to our internet just fine so I really don't understand why mine isn't working.When I diagnose the problem it says "Cannot communicate with Primary DNS Server (194.168.4.100)" and underneath it says "Network diagnostics pinged the remote host but did not receive a response"

View 1 Replies View RelatedI just recently switched from the WRVS4400N to the RV180W. I have 4 VLANs, and I want VLANs 1, 2, 3 to communciate freely, but I DONT want VLAN 4 to communicate with anybody, just Internet access. On the WRVS4400N, I was able to do this using the Firewall > IP Based ACL. I notcied that the RV180W, does not have such an option. I am sure there is something I am missing, I just cant find out how to isolate VLAN 4.
View 5 Replies View RelatedI am facing an issue to setup what I initially called simple network but still unable to put it together.On SG300-20 I want to setup 4.3 of the vlan are to separate users in to different groups and to secure data confidentiality.1 is for the NAS. All users on the 3 vlans must access the NAS vlan.All user should have access to internet via SG300 through the ISP provided router. How to configure this, I have every little knowledge of switching and routing? And the routing seems to be the issue I am encountering because I am able to create the VLANs and assign static IP address to them but not able to get them talk to each other. I use each vlan ip as gateway on each port assigned. [code]
