When a firewall reaches end of support or the Wi-Fi cannot keep up, you do not need a whole new network. BTI checks what you have, keeps what still has life in it, and replaces the rest on one plan, tested before your team relies on it.

A network upgrade is a project with a beginning and an end, but your network keeps running long after. BTI handles every stage:
We look at what you have and what you need, keep equipment that still has life in it, and size new equipment so you do not pay for capacity you will not use.
A walk-through, an inventory of firewalls, switches and access points with their support dates, an Ekahau Wi-Fi design where coverage matters, and an itemized proposal.
Equipment configured and tested before it is installed, with cutovers scheduled with you, often after hours.
An Ekahau validation survey of the new Wi-Fi, firewall and internet failover tests, VPN and phone tests, and as-built documentation with a current network diagram.
After the project, BTI can monitor firewalls, switches and Wi-Fi, keep firmware and security licenses current and handle changes. Work with your IT team through co-managed IT (add people through IT staff augmentation), or hand it to BTI through fully managed IT.
Doing all of this as one team means nothing falls between a designer, an installer and a support provider.
Firewalls, switches, access points and the labor to install them add up. BTI can arrange 3.99% vendor financing for 100% of the project, including equipment, labor and consulting, for qualified buyers, subject to credit approval. Many bank loans run 10% or more today and ask for far more collateral. Our vendor financing is secured by the new equipment itself.
Firewalls past end of support stop getting security fixes. Examples from SonicWall's own lifecycle notices:
| SonicWall model | End of support (SonicWall) |
|---|---|
| TZ 300 and TZ 300W | January 23, 2025 |
| SOHO and SOHO W | April 16, 2026 |
| TZ 400, TZ 400W, TZ 600, TZ 600P and NSa 3650 | August 1, 2026 |
| SOHO 250 and SOHO 250W | October 1, 2026 |
Sources: SonicWall end of support notice for the TZ 400, TZ 400W, TZ 600, TZ 600P and NSa 3650, and SonicWall product lifecycle tables (https://www.sonicwall.com/support/product-lifecycle-tables), checked October 25, 2026. Check your exact model, because dates differ by model and license.
Replacement options. A current SonicWall model or a Cisco Meraki MX, sized to your internet speed, users and security services. BTI moves your rules, VPNs and VLANs, tests failover, then removes the old unit. For ongoing firewall support see SonicWall support; for Meraki see BTI's Meraki services; for firewall policy and monitoring see network security.
Newer Wi-Fi handles more devices at higher speeds, so a Wi-Fi upgrade often reduces the number of cable drops you need. BTI designs and validates Wi-Fi with Ekahau: a predictive design shows where access points go, and a validation survey after installation confirms coverage and signal strength. See also commercial Wi-Fi.
Switches carry everything: PCs, phones, access points, cameras and door controllers. An upgrade is a chance to add PoE power for new devices, separate traffic with VLANs, and add redundancy for the core switch.
More than one internet line with automatic failover, SD-WAN between locations, and VPN for remote staff. Phones and video calls get priority so they stay clear when the line is busy.

When the firewall, switches or access points reach end of support, when Wi-Fi cannot keep up with the number of devices, when you add cameras, phones or access points that need more PoE power, or when you move or expand. Equipment past end of support no longer gets security fixes.
Check your exact model on SonicWall's product lifecycle tables. For example, SonicWall lists end of support on August 1, 2026 for the TZ 400, TZ 400W, TZ 600, TZ 600P and NSa 3650, and October 1, 2026 for the SOHO 250 and SOHO 250W. BTI can check your model and license status for you.
Usually a current SonicWall model or a Cisco Meraki MX, sized to your internet speed, number of users and the security services you need. BTI moves your rules and VPNs over and tests failover before the old firewall is removed.
Often, yes. Newer Wi-Fi handles more devices at higher speeds, so fewer desks and devices need a wired drop. BTI designs coverage with Ekahau so you know where access points go before anything is mounted.
No. Many businesses replace the firewall first, then switches and Wi-Fi as budget allows. BTI value engineers the plan at no charge so you keep what still has life in it.
No. This page is for upgrading an existing network. For a new building or full cabling job, see BTI's network installation services.
Equipment is configured and tested before it arrives, cutovers are scheduled with you, often after hours, and the old equipment stays ready until the new network is tested.
Yes. BTI can arrange 3.99% vendor financing for 100% of the project, including equipment, labor and consulting, for qualified buyers, subject to credit approval.
