When to call us

Signs your switches and VLANs need attention

  • Guests, phones, cameras and staff all share one network
  • Nobody knows what is plugged into which switch port
  • The network slows down or drops for no clear reason
  • Switch firmware has not been updated in years
  • The network diagram, if there is one, is out of date
  • Moving a desk or adding a phone takes guesswork

Questions

Router, switch and VLAN management: common questions

Why do VLANs matter for a business network?

VLANs keep different kinds of traffic apart: staff computers, servers, phones, guest Wi-Fi, printers and cameras. That makes problems easier to find and limits what each device can reach.

Can you clean up undocumented switch ports?

Yes. We map every port to the device or wall jack it serves, fix wrong VLAN assignments, disable unused ports and label everything.

Do you keep guest Wi-Fi off our business network?

Yes. Guest Wi-Fi goes on its own VLAN with firewall rules that allow internet but block your computers, servers and printers.

Can you troubleshoot a slow network?

Yes. We check for loops, bad uplinks, port errors, duplex mismatches, broadcast noise and cabling problems, and fix what we find.

How much does router, switch and VLAN work cost?

It depends on the number of switches and sites, how many VLANs are needed and how much cleanup the current setup needs. The first 30-minute review is free, and you get a written quote before work starts.
