Hi, I'm pretty much a complete amateur when it comes to networking, so I may need more elaborate explanations.

So, I've got my computer plugged into my modem, and a wireless router plugged into the modem which multiple devices like my phone, tablet or PS3 use to access the internet. I plug my computer into the modem directly because the speed difference is HUGE, like 10x the amount. I've tried disabling QoS, but not much seems to help with that.

Anyway, have read a bit on the topic (couldn't find much), and tried the following:
* Disabling Router DHCP and setting IPs manually, and connecting modem to LAN port of router rather than internet
* Changing router LAN IP to be in the same subnet (I think that's the term, 1st 3 groups of numbers in the IP) as the default gateway of the modem

Have had no success with either. Can anyone help on this topic? Thanks.

There is a solution that you will not need to make any changes to the Huawei. First download a manual for your Huawei model for reference.

Attach the Buffalo WAN to the Huawei LAN port. Simply set the Buffalo as a router for your network, and attach anything on the Huawei LAN ports other than the Buffalo to LAN ports on the Buffalo. You need to figure out the Huawei gateway address, so attach a computer to it and run a command prompt box on the computer and type ipconfig /all -- that will list default gateway. You will use that address as the WAN address and DNS address on the Buffalo, then set up your internal LAN with a different network address. So if the Huawei is 192.168.x.y, make the Buffalo 192.168.z.1 and set up your...

Fibre optic connection, modem (not sure exactly what it is tbh) provided by my ISP - Huawei EchoLife HG863 (http://www.huawei.com/en/products/fixed-access/fttx/ont/hg863/index.htm).
Wireless router is WHR-HP-G300N (www.buffalo-technology.com/en/products/network-devices/300mbps-wireless-n/wireless-routers/airstation-nfiniti-wireless-n-300mbps-cable-router/).

Both are in the same room.

Thanks for the reply! Could you dumb it down a bit please though?

So just to clarify, the AP is the Huawei Modem I mentioned, and I give it a static IP address, disable DHCP and WAN? Not understanding the static table part. So I basically don't need to modify any settings on the router? Hope I'm not getting this completely wrong!

No -- the Huawei is the gateway combo modem/router and the Buffalo will be the AP (give it a static IP address, disable DHCP), connect the two LAN to LAN with an Ethernet cable. The IP address that you assign to the Buffalo must also be entered in the Huawei in an area called static routes (you will need the Buffalo MAC address usually on the back or bottom to make the entry).

That is the only one of two changes to make on the Huawei -- add the Buffalo static address in the static route table. Also make sure that address is not in the available DHCP assignment range of the Huawei. For example only: if the Huawei LAN gateway address is 192.168.1.1, make the Buffalo 192.168.1.2 and then set the Huawei DHCP range 192.169.1.3 to .254 That is all for the Huawei.

All other changes are made on the Buffalo, get the manual for reference, but all you have to do is to attach a computer to it (disconnect the Huawei LAN for the moment. Change it to AP mode by giving it the LAN IP address of 192.168.1.2 (do this last or you will have to log back in on this address) -- it does not need any WAN settings in AP mode. Select a wireless channel, SSID (network name), turn on WPA2 security, and enter a passkey for security -- write that down since you will need it for every device that attaches, make sure that the wireless radio is turned on.

Would really hate your efforts to go to waste...but I just called the ISP since I was having trouble accessing the Huawei, and it seems I can't actually get into its configuration! Is there a solution which doesn't require that? Hopefully an easy variant of the above? Surely all modems must have a config!

I did try the gateway IP, DHCP address, .1 at the end of both, 192.168.x.1, with x being 0,1,10,11,100 (100 supposedly the default for some Huawei devices), but no luck..

Thanks a ton for your replies though, and explaining it in detail.
