Hello, First time poster, but long time reader

I have poor Wifi performance with the Spark provided Huawei HG630b

It may have something to do with the crowded Wifi environment I live in, and also the size of the house.

I wish to purchase a better Wifi AP, one that has the option to add an extender if required.

I am trying to decide whether to buy an integrated VDSL modem/router 

e.g. 
Asus  DSL-N66U (802.11n only, 900 Mbps max, $289)
D-link DSL-2877AL (802.11ac 750 Mbps max, $198)
TP-link TD-W9980 802.11n, 600 Mbps, $178)

or whether I should buy a standalone Wifi router only, connected to the Huawei via bridge mode 

e.g.
TP-Link Archer C7 (802.11ac 1750 Mbps, $213)
TP-Link Archer C9 (802.11ac 1900 Mbps, $240)
Asus RT-AC56S (802.11ac; 1200Mbps $259) 
D-Link DIR-880L (802.11ac and 1900, $269)

For obvious reasons, it would appear that getting a Wifi router only will give me better Wifi specs for the same money, but it will need to be bridged to the Huawei.

My questions are:
(1) Would an integrated solution offers better performance than a bridged performance since all the electronics talk to each other directly rather than via a link.

(2) Is it better to have an integrated solution at a lower Wifi spec, than to have a bridged solution with higher Wifi spec?

(3) Are there any downsides to bridge mode, besides the one time only set up hassle?

(4) Of the above routers / modems, which one would you recommend from each of the category (those are within my budget i.e. $200-300)?

Depending on the size of your house, how its built and such. Your best option may be multiple access points.

Dont use bridge mode, just turn off DHCP dns etc, give it a static ip on your network for management and plug it straight in, Essentially turning into a simple "Access point" - Realistically any "modem/router" will do this too.


There is next to no delay added, atleast that would be noticeable at all.


You have not given any real detail on what your looking at by "poor wifi performance", So are we looking at range, speed, consistency? 

As you correctly identified, Living in a crowded Wifi Environment would affect you. - Often in this case, the solution is not to simply throw more hardware at it and hope for the best.

Problem with the wifi is low coverage and sometimes even when there appears to be full bars the throughput is slow. Seems to be a common problem with the Huawei. Hard wire Ethernet seems to be ok. I always plan to use additional repeaters given size of the house (three storeies)

dont use repeaters, use access points, repeaters reduce the total bandwidth.

Can you do a layer 2 bridge with the 630b? If you can thats pretty good, in that case you may want to consider routers with flash routing features. 

1) If you have a medium sized house the cheapest option would be to buy a wi-fi access point and connect it to the LAN, and put it at the opposite end of the house to the current modem and you may want to turn down the wifi signal strength on both till you get a decent signal everywhere. 

2) You could buy another router with better (ac dual channel) wireless and disable the wifi on the 630b, which is what I think you were planning to do. 

To be honest I had all sorts of wifi problems over the years and it was mainly because i had to place the (all in one modem/router) near the master filter which was installed at the far end of the house. And I have found a well placed access point seems to be the most effective solution for so many peoples wifi i have fixed. I currently have a Unifi-AP mounted on the roof in the middle of the house and get a pretty decent signal anywhere in the house. Everything else like the TV's etc are all cabled back to the switch. If you have a bigger house you will probably need two AP's.

I hear the xClaim XI-3 is a really good unit if your budget stretches that far.. I plan to get one (or two) when i build my new house in the new year.

IMHO If you can't explain why repeater are bad you should never use them.

There are scenarios where repeaters are a possible solution, but they should really be avoided at all costs unless absolutely nesessary. Typically speaking they're not a solution, but another problem.

OK. I googled and read about repeaters vs access points. I think I get it.

I will be getting access points, not repeaters.

With this in mind, am I better getting off a few access points and not buying a new Wifi router at all? As a matter of fact, I have four power line ethernet adaptor (Netcomm NP204 no wifi function, 200 Mbps ethernet via power line) already. So will the following work?


VDSL -> Huawei (modem/Wifi) with LAN1 connected to a power line ethernet adaptor


At other locations:

Ethernet adaptor -> LAN input of Wifi access points


if the access points have higher specs than the Huawei, will they be limited to the Huawei's speeds?

Am I going to be limited by the speed of the old ethernet on power line adaptor?

you will always be limited by the slowest device in the system over the path the network traffic needs to take so if the path goes via the powerline adapters then they may be the bottle neck

Yeah that setup will work fine. And no the wireless on the Huawei doesn't affect the speed achievable on the access points.

However..

As Jase mentioned above you are limited by the slowest link in the chain, so in this case any access point will be first limited to the 200Mbps of the powerline adapters, then further limited to the 100Mbps of the Huaweis LAN ports. If all you're doing is accessing your VDSL connection this way then you'll be fine as I doubt it exceeds 100Mbps. However if, for example, you had a NAS plugged into your router then access to that would be limited to 100Mbps.
