Will the Archer C7 get VLAN support in a new firmware update? VLANs would be very useful for the Guest SSID feature. you can ask their support. But I think they will not.It's made for soho router...

It's will jump out error information when you write ?

Hi,you should provide more detail about your topology. disable DHCP on C7,and don't use wan port. how can you find they lose connect when c7 connected to dell powerconnect 5012

make sure you have done USB settings?enable storage sharing. And do you write it on PC?

it's so special, what's the version and model No. of TPLINK ADSL2+ modem? I really have not met this issue.But it cause my curiousness. What's your topology,how are you connect them?

oh,it's so peculiar~~ But where did you find it, I don't get it on utility.
