Speed issues can be caused by a number of factors including:
- Equipment failure/fault at your premises.
- Third-party software using the upstream and/or downstream capacity of your ADSL connection (includes p2p, viruses or Internet applications).
- BT Exchange contention.
- Contention on the BT Central pipes which present your connection to Zen.
- Interference or line quality/length issues resulting in an intermittent connection or temporary low line speed.
