Hi everyone, I've recently set up an old router I had (Spark Huawei Hg630B) as a Wireless Access Point upstairs to improve the WIFI signal. My main router is located downstairs and it is a VDSL/FIBRE Dual Band AC1600 Gigabit Gateyway with VoIP provided by Orcon. The router and the WAP are connected using an ethernet cable that goes from LAN to LAN. The settings of the WAP were set according to these instructions:

"

 

1. Under Home Newtork-->LAN Interface-->LAN Settings, change modem IP address to a different range than main modem (I used 192.168.3.1), and Device Name to something else as well. Save and log into the modem with the new IP address
2. Under WAN/internet settings un-tick/disable all connection types (ADSL, VDSL, Ethernet etc). Save settings.
3. Under Home Network-->WLAN Settings change SSIDs and password to be identical to the main router. Save settings.
4. Under Home Network-->LAN Interface-->DHCP Server un-tick DHCP Server, and save settings.

"

I did not change any settings in the main router. Both networks have the same name "Your New Wi-fi" and password, although the main router has an extra 5Ghz network created that the WAP doesn't.

The problem I have is I am getting very slow download speeds using the WAP, but only on some websites. For example, if I download from Google Drive, I normally get a speed of about 4MB/s, which is good and similar to what I get connected to the main router. However, downloading from Mega the download speed is no bigger than 100kB/s, which is extremly slow. I began to try diagnose why this was happening so I did some internet connection speeds using the Ookla speedtest website, which lets you choose a server to test your connection on.

What I found was that when testing using a server in NZ, I get very good results: 4.5MB/s download, 4ms ping, 2.5MB/s upload. These are similar to what I get when connected to the main router.

However, when testing using a server overseas, the San Francisco one, I get very slow results: 0.01MB/s download, 164ms ping, 0.17MB/s upload. Meanwhile, when connected to the main router and performing the same test, I get results similar to the ones mentioned above for NZ (around 4MB/s download).

So clearly it seems that the problem is nothing to do with the ISP, but with the settings of the WAP that seems to give me very slow speeds when connecting to overseas servers, but normal speeds when connected to NZ servers. I don't really know much about networks so I was hoping someone would be able to help me diagnose what could be causing this behaviour, and how I am able to fix it.

Thanks for your help!
