Network Troubleshooting & Diagnostics

Networks that drop out at random, speeds nowhere near what you pay for, video calls that freeze on schedule — we diagnose what's actually going wrong at the protocol level, not by guessing. Then we fix it, permanently.

/ When to call us

Signs you need this service

  • WiFi randomly drops and you can't spot a pattern
  • Speeds are far below what your broadband contract promises
  • Lag, jitter or freezing in Teams / Zoom / gaming
  • Smart‑home devices keep going offline at random
  • You've already had "a tech" out twice and the problem is still there
  • Your ISP insists "the line is fine" but the issue persists
  • After a power cut / lightning strike the network never recovered properly

/ What you get

What's included

  • Remote pre‑call — we resolve roughly half of issues without an onsite visit
  • Packet capture with Wireshark to see the actual traffic at the byte level
  • WiFi spectrum analysis to identify interference and channel congestion
  • Signal heatmap (where relevant) to spot coverage gaps
  • Hardware health checks — firmware, configuration drift, capacitor issues
  • ISP escalation support — we speak to BT / Sky / Virgin / TalkTalk on your behalf with the data they need
  • Identification of the actual root cause, not a guess
  • Written diagnosis + recommendation (fix in place, replace, change ISP plan)
  • 30‑day "if it comes back, we come back" promise on diagnosed faults

/ Our Process

How a typical troubleshooting job runs.

  1. STEP 01

    Brief

    You tell us the symptoms, when it started and what you've already tried.

  2. STEP 02

    Remote check

    We probe the network remotely first — saves you a call‑out fee where possible.

  3. STEP 03

    Onsite diagnostic

    If needed — packet capture, spectrum analysis, heatmap, hardware checks.

  4. STEP 04

    Root cause

    We tell you what's actually wrong, with evidence. No "computer says no".

  5. STEP 05

    Fix

    Quoted separately — could be a config change, a single cable, or a hardware swap.

  6. STEP 06

    Verification

    Once fixed, we re‑test to prove the issue is gone. 30‑day guarantee.

/ Questions

Frequently asked.

I've been told "it's just WiFi" — is that true?+

Sometimes, but not always. "It's just WiFi" is what people say when they can't find the actual fault. A proper diagnosis looks at the cabling, the switch, the router, the access points, the device, the ISP line and the broader RF environment — and finds where the real problem is.

Will I need new equipment?+

Not necessarily. About 60% of the issues we diagnose are fixed without buying new kit — a configuration change, a firmware update, a cable swap, a channel change. We only recommend new hardware when there's no sensible alternative.

How long does a typical diagnosis take?+

Remote pre‑call: 30–60 minutes. Onsite diagnostic visit: 2–4 hours typically. Complex multi‑factor problems can take a second visit, which we discount.

What if you can't fix it?+

We tell you honestly what's going on, give you the data and our written recommendation. You only pay for the diagnostic time. If the root cause is on the ISP side, we hand you the packet captures to take to them — and they tend to listen when there's a Wireshark trace involved.

My ISP says the line is fine — can you prove it isn't?+

Yes. We capture packet‑level evidence of dropouts, latency spikes and packet loss with timestamps. ISPs can argue with their customers; they can't argue with their own line stats showing the same numbers we captured.

Do you work remotely or only onsite?+

Both. We always try a remote diagnostic first — about half of the time it's enough. When it isn't, we book a proper onsite visit.
