Cisco SRO527W wireless and Wired problem

[hulu119]

Hello everyone:

I am new to this forum, I would like to ask two questions:

1.

in our small office, we are using Cisco SRP527W (Router/ADSL Modem all in one ) and D-Link DGS-1210-16 (ports) as our main network devices, our 3 desktops (Windows XP), Avaya phone system and one Brother MFC 6490CW are wired connected to our D-Link switch, port1 of the switch is connected to lan port 1 of our Cisco router, we also have 3 wireless devices connected to the cisco router throught wireless signal (one Broher MFC J6910DW printer, one laptop with Win7, one all-in-one desktop with Win8), as we know, both Switch and Router support Vlan feature, but at the present, I just use default Vlan (Vlan 1) for all our data traffic, I created a DHCP Pool in Cisco router to provide IP address to all our devices (DHCP Pool: 192.168.30.101 - 192.168.30.250, Default gateway is 192.168.30.254), 

All wired or wireless devices can get right IP address,and all of them are able to get on to the internet, the problem is wireless and wired devices can not talk to each other, for example, my laptop is using wireless connection, when I try to ping a desktop which is wired connected to switch, there is no response, however, if I cable connect my laptop to switch, I am able to talk to the desktop and use its shared resource.

does anyone could give me some clue about solving this problem??

2.

as we know, Cisco SRP 527W provide two default Vlan, one for data, one for voice, I am willing to use voice vlan for our Avaya phone system, because I use Lan Port 1 of 527W to connect port 1 of the DLink switch, so I assigned "Lan Port 1" to both Vlan, I am thinking if I do this, port 1 will be the Trunk, also on Dlink switch, I tag port 1 for both Vlan 1 and Vlan 100 (Voice Vlan), untag port 2 for Avaya phone system which is in Vlan 100, untag other ports (port 3 to 8) for Vlan 1, so I am thinking Port 1 on switch become a Trunk, however, after all the configuration done, all wired devices cannot access to the SRP 527W router.

I am wondering Is there any thing wrong with aboved configuration I made?

Thanks

Hi,

1. Check if AP Isoaltion is Enabled (Interface Setup > Wi-Fi Settings > Advanced Wireless Settings )

2. Basicaly your logic is correct. On the router the port, connect to the switch should be Trunk - VLAN1 untagged, VLAN100 tagged. The same is the configuration on the switch port connected to the router.

The switch ports where you connect a PC, should be Access, VLAN1, and where you connect a phone should be Access, VLAN100.

So if the PCs and phones does not obtain an IP form the router,first you need to check where the problem is comming from-the router or the switch. So plug a PC directly to the router and see what will happened

Hi Kremena:

Thanks for your reply.

This afternoon, I enabled Voice Vlan which is Vlan 100, I assigned SSID2 and Lan port 1 to this Vlan, after that, I made sure the "Intervlan Routing" was enabled, then let my laptop connected to Vlan 100 wirelessly, I found out I can ping all devices in our network (including Vlan 1 wired devices and wireless devices), and connected to them to used their shared resources.

so for default vlan 1, althought the wireless and wired networks are in the same subnet, it seems they are in different vlan, we do need some ways to bridge the two interfaces, does SRP 527W provide such option or it was designed like this for security??

Thanks
