'G. Fast doesn’t work with TalkTalk WiFi router connected via WAN port to LAN port on Openreach modem. Cannot connect to Internet although internet light green on modem. The LAN light on modem is not lit I’ve now got 3 Sagem 5364 fast modems. The original and two replacements that have been sent out to “fix” the problem. None of them work so it must be either configuration or a compatibility problem. I’ve had no service since beginning of the week and am waiting until next week for a call from case manager. This problem seems to have been going on for months/ years. There should have been solutions or conclusions to previous posts but none have been posted.
Let me me see if I understand the issue:
Openreach Modem :
* LAN port is disconnected or no power on the port.
Sagemcom Wifi Hub (Router)
Modem LAN to Router WAN (ethernet)
Some things could try while you wait on TalkTalk support:
1. Test with a different ethernet cable to exclude a ethernet cable fault.
2. To exclude any fault on the modem LAN port. Have you tested the Internet connection by plugging in an ethernet cable to a pc/laptop from the modem’s LAN port ?
3. If the cable and LAN port are OK, try a factory reset (pin hole) on the Wifi Hub Router.
Thanks for your answer. LAN port on Openreach modem works fine and I can get to Internet with Ethernet cable connected to another device using the modem lan port with download speeds of 80+. Have reset router as suggested - in fact tried all 3 - but no activity on Router lan port. No light. It all seems to point to the Wan port on the routers not being activated or configured correctly but surely routers would not be sent out like this?
That is strange, the Sagemcom WIFI Hub should auto detect if xDSL or Ethernet is connected for WAN. If the modem is working with a PC, should be no differnet with a router.
I've did a quick test,
A long shot - login to the router and check on the Internet Connectivity settings page, that the router is set to DHCP:
There is nothing else to configure for the Internet Connection.
I think your router configuration software or firmware version is different to mine. DHCP is under WiFi Hub Settings and Enable button is set to OFF. Under Ethernet WAN status shows as DISCONNECTED with no option to change it. Under Internet Connectivity there is just 3 settings - DNS (set to Obtain DNS Automatically)
- DNS 1 (set to blank)
- DNS 2 (set to blank)
I enabled (set to ON) DHCP and tried WAN connection again. It made no difference so I set it back to OFF. Whilst looking at router maintenance tab and logs I noticed this: 01.01.2013 00:05:17 Module WETH Wan Ethernet connectivity has been disconnected. There’s no setting that can find anywhere for this.
I also tried connecting an old laptop with an Ethernet cable to the router WAN port. It did not activate.
I think TalkTalk need to ship you a new router with the appropriate firmware.
As you can’t connect to the internet with the supplied routers, there is no way to update them.
Maybe ask for a Huawei Wifi Hub instead of the Sagemcom.
Worth noting the firmware of the router you are testing with.
Hopefully this gets looked at by the OCE team and they can get you the correct Router out quickly.
I am sure they will help get you back online.
i’ve already had two Sagemcom routers which makes a total of 3 with no success. So, would the router you send be a Huawei one as suggested? There’s no point in sending another SagemCom unless it’s been configured differently. I have been doing tests all morning with Chris with my existing routers without success and I am waiting for his reply to my last test. It was also not successful. I don’t want to confuse things but I’m quite happy to try a different type of router if you can get it out as quickly as possible as I’ll be entering 2nd week with no service tomorrow.
Our product team have confirmed that the sagemcom router will work on Gfast with any of our firmware versions and so should work fine with 1400t.
We could try the Huawei hub, would you like me to send one?
Good Morning Chris. I think that’s worth trying. Please send one as soon as possible. If the Huawei hub doesn’t work, I think I need to give up and would like then to revert to my previous package with my original router - which is the one that does have the latest firmware version anyway. The Openreach engineer did try to go back to the way things were before but I think he had marked the job as “completed” and consequently you had already changed things at your end for g.fast and that didn’t work either. He then did the wiring for g.fast again in the expectation that a replacement Sagemcom router would work - which it didn’t. Thanks
I'm sorry about that. I ordered the Huawei but if the Sagemcom has been sent instead, it's because that's the router that's specified for G.fast. Could you try the new router and new cables provided with it. If it still doesn't work please let us know
