    using second router to boost wifi

    I have home plugs and a second router. The second router is a dlink (615 I think) which I think supports custom firmware if needed. I conencted it up and gave it its own wifi and things seem to work okay but not great. I notice speed when connecting to it is quite a bit slower and there is lag on my network now. Can someone give a few pointers on what setting need to be set on the second router. For example do I need to change its mac address?

    Oh also I have a virgin superhub 2. Is it possible to put custom firmware on that? as its much newer and has 5ghz wifi so would likely be better

    From your description you've set up 2 wifi signals - 1 from the vm superhub & 1 from the dlink? It would be better if you set up the dlink router in bridged mode (if it supports it) so that it boosts the signal from your vm superhub - that way you don't have to switch wifi depending on which room your in.

    Setting up bridged mode is usually very straightforward - it's usually going into your router settings, selecting bridged mode, and then entering the SSID and password for your primary router.

    I had a similar situation with a weak signal with this combination (2nd router & home plug) due to wiring in an older house, and I found a better solution was to move the bridged router to a location where there was a strong signal from the primary router, and I then could extend my wifi signal more reliably.

    Yea pretty much but main router is a sky q hub. I was thinking a separate wifi would be better as it wouldn't interfere with the main wifi and all data would go through the powerline adapters? I don't think the router has wifi bridge mode as is anyway but I think I can install dd-wrt on it which will likely have all the settings I need.

    It all goes down the same broadband connection anyway, so it's just experimenting to see how you can get the data to the modem fastest I suppose.

    One thing to check if you're using 2 separate wifi networks - ensure they're on different channels. Also check the wifi signals from your neighbours, as most people leave it on the default channel and it can get a bit crowded.

    There's simple wifi analysers available that show you what channel a wifi is broadcasting on. I use a free one from the win10 store - surprisingly called "wifi analyser" I'm sure there are others with more features etc, but for what I use it for, it is more than adequate.

    just 1 ssid would be nicer actually. I'll play with the settings and do some tests to see what works best. thanks for the help

    I also have a similar set up with the same wifi SSID but on different channels. Your electricity wiring/circuits may be restricting the speed you are getting over the powerline adapters.

    Hopefully you're only running it as an additional access point and not full DHCP server and firewall.
    You only need one DHCP server and firewall. Also remember to drop your transmission range as more power doesn't mean a better signal if your wifi aps are fighting over signal strength. Remember it's about just using enough power to get the job done and not seeing how far down the street you can get your wifi signal.

    well thats the idea but I'm not 100% sure I've got all the settings right. they are hidden between various menues and its a bit confusing. I set its ip different to the main router and then added that ip to the main routers dmz (no idea if this is something I should do or not)

    ​Shouldn't need dmz as the 2nd router is just an access point so you've dmz'd your own network. Everything is controlled from the 1st router as that connects to the internet it also runs the external firewall.

    I would connect the two together with a switch through.

    Don't bridge a wifi AP to another AP. It will drop your whole wifi network to a lower transmission speed. You ca easily use more than one wifi AP as long as you ensure that there is sufficient channel separation. Make sure there is a 40mhz gap between them or they will clash and create weak spots.

    Also, use the same ssid is fine. Roaming between the APs will then depend on the client devices ability to retain a signal. If you find that a phone or laptop retains a connection to a second wifi AP on the other end of the house despite being closer to the first, then adjust transmission power.
