Slower internet speed when in bridge mode

[Polanskiman]

Hello everyone,

 

I recently moved from TOT to AIS with their Power Boost 100/100 Mbps package. I have my own router, an Asus DSL-N55U_C and I have asked AIS to configure their Huawei router in bridge mode so I can use my own router. All seems to work fine except that my speed have decreased to:

- Wired: somewhere around 80D/70UMbps wired (yes I changed lan cables to make sure it was not a defective cable)

- Wifi 2.4Ghz: I am getting somewhere around 70D/65UMbps.

- Wifi 5Ghz: I am getting somewhere around 105D/65UMbps

 

When using AIS's own router I am getting the full speed D/U on 5Ghz but only 100D/80UMbps on 2.4Ghz

 

Anyways has anyone experienced these speed drops when in bridge mode? I am also a bit confused as to why speeds are actually better on 5Ghz Wifi than on Gigabits BaseT port. That doesn't seem right to me.

It happened to me. See this thread.

Hi,

 

Thanks. I did read your thread prior posting. I don't think it is the exact same issue although similar. I checked the binding port for bridging on the AIS's router and only LAN 1 is used for bridging. So I think the problem is coming from another bridging configuration setting because my download is ok, only the upload is slower.

 

Actually, I rechecked my speed on another wired section of my network and I was getting 102D/75U. Reason I was only getting 80D/70U before was because I was using my NAS to speedtest and thinking about it I think it is due to the bond configuration I set up and MTU.

 

As for my Wifi 2.4Ghz getting slower internet speeds I think it is to be expected as 2.4Ghz offers slower data speeds and 70D/65U seems to be around the normal limit for one stream. Even when not in bridge mode I was getting similar to slightly better speeds but really nothing much different on AIS's router 2.4Ghz wifi.

 

So the only problem remaining now I think is the upload speed on bridge mode. I have contacted AIS and they will be doing some further tests later today. I will update this thread accordingly.

When you set router to bridge mode, do you disable wireless radio on AIS router?

if not, 2 wireless devices next to each-other will nullify / decrease wireless performance greatly.

Yes of course. All wifi channels are disabled on the router.

Some positive news but not yet resolved.

 

I contacted Asus since AIS said it was not them causing the issue. So I did. Asus initially said my router did not have GbE ports and I needed to buy a new one, so I answered <deleted> since it has 5 x 1Gbe ports. Then they advised me to reset the router to default settings and make speed tests. To my surprise I was seing full speed both on download and upload. So the problem seems to be coming from some erroneous setting in my router or perhaps the configuration being partially corrupt because honestly I can't see what WAN setting was off. Once I pinpoint the culprit I will report. Might be useful someday to someone.

I haven't been able to find the exact reason why the slow speeds despite me looking into every setting possible.

 

A factory reset of the router did solve the problem though and now it is all working fine.

It's not what you're asking, but I opted not to use my AIS-provided router in bridge mode but to leave it in router mode and to plug my other router into it and assign it a different subnet, and I turn the WiFi "on" on both routers but give them different SSID's.

 

I might not be looking at it correctly but I think that's better for security. What I do is set the AIS router to use the subnet 192.168.1.xxx and set the SSID of that router to "visitor". My own Asus router would connect to that subnet and be configured such that when devices are connected to the Asus router (either by wire or by WiFi) they will be assigned IP addresses on the 192.168.2.xxx subnet. What I do is connect all of my devices to that 192.168.2.xxx subnet and let our maid and visitors to our house connect to the Internet using the "visitor" SSID which is on the 192.168.1.xxx subnet. That way visitors to my house would be able to connect to the Internet but would be unable to connect to any of my devices unless they are ingenious enough to figure out the IP address of the Asus router and guess its username and password.

I am not sure what router you have but many decent routers have what is called "guest networks" which basically provides Internet connectivity for guests but restricts access to the local network. That is what I use.

 

The reason I need to put the AIS routeur into bridge mode and my router as main router is because of an ID tagging function that my router does not support. In our office we are using TOT and they provide the exact same GPON that the one I have in my home with AIS. With TOT though I am able to bridge the router (which is also same I have home) directly with the GPON. But AIS uses WAN ID tagging and my Asus routeur does not support that, reason why I can't connect my Asus router to the GPON directly like we do in our office but instead I have to use AIS's router for bridging.

Update your firmware as well.

That was the first thing I did. There is no firmware update for that Asus model since 2016.
