Cable broadband modem
I use Virgin media cable for our home based office - excellent, no complaints (currently uses Netgear 54 Mbps Wireless Router WGR614-6VGUKS modem/hub).
Other than the server (hidden behind the TV at the access point in the lounge) all other access, currently three PCs and 2 wireless + 1 wired printers), are on wireless connectivity with no problems to date.
However - expansion of business means using a second room as an office in the near future and this is at the limit of current wireless range.
As some form of upgrade may be necessary anyway, would welcome any suggestions in terms of best kit for improved speed/range etc.
Going wired is not an option.
