eFibre Wireless much slower than wired.

    I just got eFibre today. I am getting 70 with an Ethernet cable but half that when using wireless. I have tested it with only 1 device connected, all wireless devices in the house switched off, tried several different channels. The wireless adapter on my main device is a Broadcom 4313GN 802.11b/g/n 1 x 1 with the latest driver. The other 2 devices connected (Laptop and smartphone) are both reporting half speed. Any ideas?

    How long is a peice of string?

    Wireless G really maxes out at about 25Mbps in a best case scenario, wireless N can get between 40 and 50Mbps if your lucky and both devices are spanning 40mhz. If a G device is active at the current time, the network runs at G speeds, combined with the fact its half duplex, so now your at maybe 10Mbps. Unless your router is dual band capable(2.4ghz and 5ghz) and both devices are using only 1 frequency. A wireless AC device can pump out close to 90Mbps real world speed, but needs both channels at 40mhz without any slower devices gumming it down. And of course on top of all of that, your most likely using a usb adapter, so you are unlikely to get more then 40Mbps out of that either. And then there is your neighbours, wireless channels and interference.

    Not sure if it is dual band. Its set at 2.4ghz and the selection to change it is greyed out. (Its an eircom F1000 modem by the way) I am using a built in wifi adapter not a USB one. I have it set to 802.11 n ONLY with no great differnce. I set it to 40 mhz and chose a channel with least interference. Half duplex I dont understand. Maybe the modem is not capable of 70 ? Does eFibre only work with the Eircom provided modem or can I use a generic one?

    better off buying a decent dual band wireless router and bridging the f1000 to it.

    Firstly can you recommend a dual band router and do I still need to use the Eircom one? Secondly, shouldn't Eircom provide a modem suitable for the job?

    you have two options

    1. buy a dual band vdsl2+ router that supports vectoring (this is important - it MUST support vectoring other wise you'll waste your money)

    draytec 2860n should do the job

    2. buy a normal dual band router (not adsl router) and connect it to the f1000 modem and disable the f1000's wifi and just use the 3rd party modem for wifi.

    any netgear or dlink should do nicely

    I just got efibre at home and i have the same problem. I'd be a total n00b with routers and the like, would this netgear one do the business?

    Thats the DGN version, you want the one without a modem.

    I have the 3800(very similar) and I can get max 115 when right beside it. Through two walls(cavity block) its down at 65(when 2.4Ghz does 60) so its worth bearing in mind the fact that 5Ghz has shorter range/poor penetration.
