Glad to hear that

I'm aware of 7.01 firmware routers and you have nothing to worry about. If you notice your 7.01 firmware, the login page lists all the accounts on the system. In the latest 7.05, it doesn't do that because they want to 'hide' the secondary operator account.

You only have 'admin' and 'user' on your 7.01 beta tester firmware. 7.05 customer firmware has 'operator' and 'admin' so you have nothing to worry about, just don't update to 7.05 haha

I don't have the .bin file but i have the mtdblock dumps. But if you disable tr-069 + change the pass you should be fine from getting 'disabled' by them I think.. the dir-615 was always sending out random HTTP requests which I caught on wireshark but didn't catch my attention till they matched the tr-069 settings so assume its that protocol.

Nah, sites having some issues for now. It's not on a dedi box, just my shared hosting I use occasionally. See how it goes, if its still down by 2pm+ I'mma call the hosting provider.

The setup pics were actually on LYN about 1 month+ ago.. just uploaded them on my site ( http://unifi.athena.my/ ) in the FTTH Wiring section. As for #6, yes you can.. read the custom router guide. #7, depends if you're doing a FTTH install or VDSL install (high-rise). FTTH will give you a completely new line.. VDSL will use your existing copper I think.

Yeah I noticed that too, I can't even see the Fragnetics servers in the BFBC2 server list anymore.. but my friends on Streamyx aren't having this problem. Should notify TM about this <_>

Update : Called their tech support line and told them about this. Seems to be a Unifi routing problem since Streamyx users aren't affected. They asked for a pingplotter to fragnetics so I sent them your link

At Unifi launch.. the ping was 9ms.. then after 1-2 weeks became 30-40ms.. then it was 9-10ms again. Now it's 205ms+ :S

I don't know how some people can still use 1mbps.. 2mbps is usable, 1mbps feels like dial up nowadays. For ADSL, its worse since the uplink gets saturated so easily. When your PC downloads some Adobe or antivirus update in the background, the whole link starts to lag :S

Funny thing is Unifi can support 100mbps+ in its current state, they just don't want to give it to the public because they have no competition

Which part of US and Europe? Other countries aren't as tiny as us, there can be a huge difference in depending on where the server is located.

But generally, I get about 190-193ms to WoW tunneling servers in the US (calpop datacenter). 188ms is the lowest latency I've ever seen for US servers on Unifi but the average is around 230-260ms. I wouldn't recommend getting Unifi just for ingame latency since switching from ADSL to Fiber only shaves off 10-15ms. Sometimes they change the routing and the ping to Fragnetics servers just gets totally screwed up. Till today, they haven't fixed the latency with fragnetics and I'm being forced to manually reroute traffic intended for fragnetics network through my old streamyx router.

However, I would recommend getting it if :

1) You need the extra download and upload speed (and you have a lot of people using the Internet simultaneously at home)
2) You need the stability that FTTH provides (no stupid blinking DSL light issue and 30 seconds to establish a PPPoE link)
3) You need a stable connection with extremely low latency within Malaysia (2ms+ to TM cyberjaya datacenters, 1ms to other Unifi users)
4) Your home gets hit by lightning all the time and you want it to stop (or rain makes your DSL link unstable)
5) You like streaming stuff on Youtube

Overall I think Unifi is a step up from Streamyx and you definitely will be able to feel the difference even coming from a 4mbps package.. but if you're just getting it for 1 FPS game I feel its not worth it. I used to be able to play in EATW at about 60ms, now even though the server list says 60ms+.. when I go ingame it shoots up to 500ms and is pretty much unplayable.

How can there be zero difference for latency between ADSL copper and fiber? If you compare the latency to the first gateway outside your home network between streamyx and unifi, even though they have the same address there's at least a 10-15ms difference. Then you have fast path and interleaved mode which significantly alter the latency for the link.. not to mention poor copper quality affecting the data transmission itself. Fiber as a medium is definitely better than ADSL over copper in terms of everything. Routing is another story.



192.168.1.1 is my 20mbps Unifi gateway
192.168.2.1 is my 4mbps Streamyx gateway

First pingtest to 219.93.218.177 (first hop after home gateway) is via Unifi
Second pingtest to 219.93.218.177 is via Streamyx

Traceroute's speak for themselves.. there's an obvious difference in latency between ADSL over copper and GPON. Between using copper and fiber (taking in account the mediums alone), there is no difference in terms of latency.. but when you compare the protocols used over those mediums, there's a noticeable difference. Even the VDSL Unifi users have this same latency pattern with Streamyx users so I doubt you're going to see these 1ms pingtest readings if you're using Unifi over VDSL.

I think you have to contact TM about it.. it's set on their side. Might want to ask 76radius about it too since he has access to the VDSL modem (managed to make it tag/untag VLAN 500 directly to use his own router).. maybe there's some settings you can play around with in there.

@g-string

Are you on Fiberhome Unifi or VDSL Unifi? I've never experienced that before on XP/Win 7/Linux but honestly, the DIR-615 which is provided is crap. Some people are having issues with basic port forwarding, wireless dropping Internet connections (VPN links), weak wifi signal and the DIR-615 locking up under heavy load.

@ihsan

If you look at any ping comparison in real world tests between Unifi over fiber and Streamyx, Unifi will always have the upper hand in terms of this base latency. For local servers, I have yet to see an ADSL line constantly pull <5ms in any latency test -- even with identical routing.

In your opinion, why is it that Unifi over fiber can achieve these 1ms+ latency readings whereas ADSL over copper cannot? You say its because of the routing that Unifi users enjoy these speeds and not the medium (and protocol) being used. Then why is it that Unifi users on VDSL have 20-30ms+ latency whereas Unifi users on FTTH have 1ms+ latency? They are put on the same IP block and have identical routing at the IP level, yet this is the case?

There are numerous articles on broadband and DSL forums stating that interleave mode for VDSL (which is what Unifi VDSL users are put on) causes an increase in latency because its used as a form of error correction at the physical link level. It's the same case with ADSL users.

http://www.kitz.co.uk/adsl/interleaving.htm


So therefore, I say that the protocol used over these two mediums (copper and fiber) is what is causing this difference in latency. Regardless of where you're sending data to or whatever routing you have, there is always going to be this 10-20ms+ base latency increase on xDSL lines (even Unifi over VDSL) compared to Unifi over fiber because of the protocol used at the lowest level which adds this delay.

I agree with you that if you compare copper vs fiber directly, there's no difference in latency if you're using the correct protocols. However, in the case of xDSL copper vs GPON fiber optics.. fiber definitely gives you reduced latency over copper.

I don't think it has anything to do with routing. Even if Unifi FTTH had identical traffic priority, routing and return paths as Streamyx users.. this 10ms+ latency difference would always be present because it's occurring at the physical link level.

@dmc0105

Any wireless card will do as long as its Wireless G or N.

I'm pretty sure that light travels slower in different mediums. Have to look at the index of refraction. -- http://en.wikipedia.org/wiki/Optical_fiber...x_of_refraction

But ihsan is correct when he says there's no difference in latency for copper vs fiber. There is a slight delay but its negligible at this distance (<5km from exchange). I believe whats really causing this large 10/20/30ms+ base latency increase is the ATM cell encapsulation and fast path/interleaving mode (error correction) which not only has high overhead but also increases the latency of the physical link for xDSL connections.

Unifi FTTH doesn't use ATM encapsulation, its purely digital and establishes a private IP subnet immediately when the fiber optic connection is made. That's why Unifi VDSL users have way higher latency (matching Streamyx ADSL users) that Unifi FTTH users don't. Regardless of what kind of routing you have at the IP level, every cell/frame/packet will always be subject to this delay when it leaves your home network because I believe it's being caused at the physical link layer.

Ooh I wasn't aware of that I assumed at first glance Unifi VDSL was on ATM since it has the fast path/interleave mode setting and I personally have never seen that outside ATM infrastructures.. but I've never accessed the modem configuration myself so I can't be sure. Maybe one of these Unifi VDSL users can confirm what kind of protocols are being used on the physical link

But yeah, the interleaving causes a significant increase in latency. Just ask archonixm about it Hopefully TM will allow them to test out fast path mode then we can have a comparison between fast path Unifi VDSL vs Unifi FTTH

.. and you're forced to use a horrible set top box with bad HDMI output quality

I would not know since nobody has offered to assist me in pentesting the IPTV network. At this point, I would need someone who has access to the Unifi IPTV network and has some knowledge in networking or using Linux. They've attempted to lock non-STBs out from the IPTV network by preventing their DHCP server from giving out leases to systems without the proper DHCP request options. Easy to bypass this but yeah, need to use Linux.

My original intention was to use the IPTV network as a free unmetered link for private file sharing/etc.. still seems possible at this time but I can't take any measurements without the help of another user.

I was also working on the STB firmware for a bit :



Managed to carve the firmware update out of a wireshark dump, then I located + carved this cramfs filesystem from within that firmware image.. the firmware still has other stuff in it though like the boot logo, some button images, etc. Made my own tool to check it and read out the information stored in the filesystem for me so that I could rebuild it properly.. but the cramfs filesystem has been altered in some way by Huawei that it wont pass a CRC check. Maybe I didn't extract it out properly idk :S

There's some interesting stuff they left in here like bcm and rt73 wireless kernel modules. STB might even have wireless functionality, who knows lol. I guess the most that I can do at this point is to re-skin it from that awful orange and blue theme

Added the IPTV configuration article today. I believe someone posted the first password to access this menu in the V4 thread but I've put up the secondary password which is required to save the changes to the box. Enjoy
