Configure the Connection Mode Settings

Options are Auto, DSL or Fibre.
Use Auto or DSL for a fibre connection.
The "Fibre" setting enables the EWAN port for use with a separate modem.

Configure the Internet Connection Settings

Optional settings:

Service Type:  TR069 > Enabled you may get Updated pushed from Talk Talk, disabled may prevent the ISP from accessing the router.
Static DNS:  > Disable to use Plusnets DNS or enable to specify your own dns settings.

"Remote Management" is enabled by default, this can be disabled in the maintenance menue.

Enable Reply to Ping From WAN

By default the firewall blocks ICMP packets from WAN.
To over ride this ICMP block and get  TBB's quality monitor working:
We need the following firewall rule and strangely we also needed to enable TR069 in the internet connection settings.

Ping Graph for the HG635

The layer of yellow (maximum latency) on the graph is something like 20ms deep.
This is unusual, my other routers show only a thin yellow line when the connection is quiet.

I haven't see a problem with latency while using this router so doubt this is anything to be concerned about.

Initial impressions of the HG635

The routers 2.4 GHz wireless signal is significantly stronger then Plusnets TG582n router.
Wireless n bandwidth can be set to 20 MHz, 20/40 MHz or a neighbour unfriendly 40 MHz.
Both 2.4 GHz and 5GHz wireless can be used at the same time.
I find 5 GHz wireless to have about the same range as the TG582n on 2.4 GHz.

4 Gigabit ports.
Gigabit needs 8 core ethernet cable, with 4 core it default to 100mbps ethernet.

The User Interface and Features.
The GUI is pretty basic, much like the Technicolor, although it's much more responsive to navigate than the TG582n.
All the basic features are there, firewall (very basic), port forwarding, DMZ, wireless WPS and access rules.
Also DHCP, UPnP, and content sharing.
DNS can be set from within the GUI.

The biggest down side is there's no telnet access for more advanced settings.  Solved

VDSL Performance
Unfortunately I have a pretty poor line, so it's difficult to make a accurate comparison with BT's modem.
All I can say at present is that it appears to give much the same sync speed and through put as both BT's modem and my TG672 VDSL router.

My VDSL2 Stats from the HG635

Internet Connection

DSL synchronization status:                           Up
Connection status:                                         Showtime
WAN IP Address:                              
Primary DNS Server:                          
Secondary DNS Server:                      

Line Quality

Upstream line rate (kbit/s):                            1296
Downstream line rate (kbit/s):                        23105
Upstream noise safety coefficient (dB):          6.5
Downstream noise safety coefficient (dB):     6.4
Upstream interleave depth:                           0
Downstream interleave depth:                       0
Line standard:                                              VDSL
Upstream line attenuation (dB):                     62.8
Downstream line attenuation (dB):                 26.1
Upstream output power (dBm):                     6.8
Downstream output power (dBm):                11.3
Downstream interleave depth:                       None
DSL up-time:                                               1 day 23 hours 34 minutes 17 seconds

The stats show only basic information.
The interleaving result is wrong -- my line has a downstream interleaving depth of over 400.
The DSL up-time is the routers up-time and not the connection up-time.


After using this router for many months there's only a couple of problems I've had:
1) The routers DNS server is slow and if I use custom DNS setting they disappear after a while leaving no DNS service.
My work around is to configure the DNS server settings in each of my devices network settings. This is not a issue for me but I can imagine it being a problem for some.
2) Every few days there will be a incidence were the router doesn't respond for a minute or two. I suspect it's caused by the wireless, may be it's slow to come out of sleep. This has never been a great problem for me so it's not something I've paid a great deal of attention to.

Hidden Pages

The fact that these pages are hidden suggests that these features may have problems.
Use with caution.


Huawei have released their open source firmware, it's available for download here:

You can find the compiled firmware version 1.014t at the following location in this zipped file:
This is what we think some of the files in this folder are but as always USE AT YOUR OWN RISK.

HG635v1.04t_multicast_with_multicfg_main.bin -- has telnet enabled -- security risk.

HG635v1.04t_multicast_with_multicfg_pack.bin -- it looks very much like the vanilla talktalk firmware, telnet disabled.

HG635v1.04t_packet_config.bin  -- just a conf file which enables telnet -- security risk.

HG635v1.04t_main.bin  -- telnet disabled.

It is strongly recommended not to use the firmware files with telnet enabled, these firmware files are considered a security risk, after a while the routers telnet port 23 becomes open to the internet.

A much better method to enable telnet is to modify the routers config file by using the backup and restore function. The config file is encrypted but this can be easily dealt with using the tool to decrypt and encrypt the file.
Thanks go to Ayosi for creating this tool.

This is my restore conf file with telnet enabled. Use at your own risk.
