Telecom questions, clearly answered

Internet is the external service connecting a location to wider networks. Wi-Fi is one local method used by devices to reach the router. A fast line can still feel slow when local Wi-Fi is poorly designed.

No. Performance varies by coverage, spectrum, congestion, equipment and fibre plan. Fibre is often more stable; 5G can be quicker to deploy and supports mobility.

Satellite can serve remote, temporary or hard-to-reach locations. Installation, sky visibility, capacity, latency and weather resilience must be assessed.

It is a maximum headline figure, not a guaranteed result. Real throughput depends on the access network, local network, devices, congestion and test method.

No. It reduces risk when it has sufficient capacity and independent dependencies. Power, ducts, towers or upstream systems may still be shared.

Position access points carefully, use wired backhaul where possible, reduce interference and add managed access points based on a site survey.

Exact locations, users, applications, expected traffic, indoor layout, continuity needs, installation constraints and desired timeline.

Compare coverage evidence, realistic performance, equipment, installation, support scope, service targets, exclusions, contract term and total cost.

FTTH means fibre reaches the premises, but observed performance still depends on the subscription, in-home network, Wi-Fi, equipment and the service being used. Check eligibility and installation conditions for the exact address.

Video calls react strongly to latency, jitter and packet loss. A short speed test may not reveal Wi-Fi interference, device overload, busy uplinks or a momentary network problem.

Usually no. A separate guest network, with suitable isolation and clear access rules, limits exposure to business systems. The exact design depends on the router, firewall and operational needs.

It can extend coverage, but each wireless hop shares radio capacity and can be affected by walls and interference. Wired backhaul remains preferable where it is practical.

Confirm the address, current contract commitments, building access, installation timing, equipment return, number-porting needs, backup arrangements and who will manage the transition.

They should avoid shared risks where possible: different physical entries, ducts, access technologies, power arrangements and upstream networks. Independence is a design question, not only a second invoice.

A VPN can protect traffic in transit to its endpoint, but it does not remove every risk. Keep devices updated, verify the network and service, use multi-factor authentication and avoid exposing sensitive systems unnecessarily.

It matters when applications, devices, remote access or future growth require modern addressing. It should be planned alongside IPv4, firewall policy, DNS and monitoring rather than enabled without review.

Record the room, device, time, network name, signal level, applications affected and whether a wired or mobile connection behaves differently. This evidence is more useful than repeatedly restarting equipment.

No. QoS cannot add capacity; it decides which traffic is treated first when capacity is limited. It works best when the link is measured and policies match real priorities.

Test loss of the primary link, automatic and manual failover, critical applications, remote access, voice, alerts, restoration and the written escalation process. Record the outcome and correct weak points.

There is no single interval. Track vendor security notices, support status and change windows; test important updates where possible, keep backups and avoid unsupported equipment for critical services.

Simulate a controlled failure of the primary link, test priority applications from real user locations, and measure both failover and return.

It connects each site and device to its version, contract and dependent services, making diagnosis, changes and replacement easier.

Not necessarily. DNS, identity, VPN or the application may still fail. Verify a complete user task after recovery.

Check address changes, CGNAT, IPv6, firewall rules and the remote access method. Do not expose an administration interface directly to bypass the issue.

Not necessarily. Check the zone or VLAN, IPv4 and IPv6 filtering, and access to administration interfaces from a guest device.

Calculate each price period over the same total duration, then add installation, equipment, options and exit costs. Show unknown costs and possible changes separately.

No. It is a probe without a reply within the chosen deadline and must be counted separately. Replacing it with zero artificially improves the median and percentiles. With no replies, these statistics cannot be calculated.

Packets may wait in queues when a link is busy. Compare idle and usage with the same tool and destination, distinguishing Wi-Fi, access, device and server. The difference alone does not locate the bottleneck.

Packet size and the VPN path may be involved, alongside loss or the remote application. Compare the same transfer with and without the tunnel when network policy permits, then ask for MTU and PMTUD checks. Do not disable the firewall globally as a test.

Resolvers retain replies for their TTL; a previously nonexistent name may also be negatively cached. Compare the authoritative server, the resolver in use and the test time. Flushing your device does not clear other users’ caches.
