You are likely to be constrained by the wifi router transmit power itself. TM supplied router does the intended function but its pretty much entry level. In some cases you may need another router operating as an extender or WDS (wireless network distribution) for the areas where wifi signal is too low. Or it could be due to interference from other wifi routers in your location (eg neighbours). 802.1 under 2.4Ghz has only like 11 or 13 channels and even then its like very much less than 10 wifi can operate in the same location without interference. Plus 2.4 Ghz devices including cordless telephone etc are know to cause interference.

In essence, there are many variables that may cause a drop in the range of your wifi and pretty hard for us to tell you what is the cause. Solution is better router or extend the network.

Have you tried a direct cable connection and check the speed? I have seen enough issues with too many wifi networks in the same location causing poor speeds. Would be useful to eliminate this as an issue.

Have you tried a direct cable to confirm its the router?

If the direct cable is problematic as described its likely to be over-heating. Try placing the router away from the modem .. say 20cm or more. Also check if the router feels warm to touch or hotter. I had seen wireless routers randomly disconnect and the cause was traced back to over-heating because other equipment were close by. Check by turning off wireless when you test with direct cable.

Once you find direct cable is ok and the problem arises for wireless only its likely network congestion. In my area its like around 10 or more wifi running at any one time. With 2.4Ghz having 3 effective radio channels and it does not help with some D-Link routers using dual-channel for 802.1n (some vendors for example only use one channel for 2.4Ghz to prevent over-crowding) you will see lots of latency and wifi disconnects. I run both 5Ghz for my gaming systems and 2.4Ghz on other stuff like PS3 and iPhone. The 2.4Ghz shows plenty of drops even though the signal is quite strong - prove of network congestion. And this usually also shows a much much lower speedtest probably because of packets retransmits. Turning on the "network robustness" option on my router helps a bit at the expense of throughput though.

Then I would suggest you try running on cable for a day or so and wifi off to confirm this.

On your question, actual throughput using dual-channel 5Ghz is around 215Mbps on average. Reckon it should be much better performance than 2.4Ghz with everything considered. I get around 200ms to 300ms on MMO gaming to North American servers and don't use any tunneling services. Most of latency issues are traced back to problems on the 2.4Ghz at least in my case which is why I switched to 5Ghz. By the way, N-capable devices may not necessarily run on dual-bands so you need to check. If you go the route of 5Ghz the very nice tutorial to convert the DIR615 as a VLAN switch works like a charm. Invest in a good router with a solid heatsink and you won't need a cooling pad. My gear runs 24X7 for years now and don't have any fans or pads on the equipment which are housed inside a cabinet

My friend in USJ speed seems fine. What he noticed is too many people using wifi in USJ and at times his pc gets slow connection to the router. Do what he does - speedtest using a wired cable (and router wifi turned off) to confirm its not the wifi router.

Given that routers are inexpensive perhaps configuring the DIR-615 as a pure VLAN switch and getting your own router would save a lot of time, pain and downtime in the longer term. I reconfigured the DIR-615 on the same day as my Unifi install and never had low speeds, disconnects etc

For IPTV I went with cable rather than homeplug after looking at some folks tests on YouTube comparing homeplug against 802.1g speeds etc. Its not that great and would be very dependent on the quality of copper and age of copper in the home. You can use 3M clips to neatly run and secure your CAT5 cable neatly as an alternative. And you can paint over the CAT5 cable to hide it if you so wish. Much less work and hassle I suppose. YMMV

Don't seem to have this problem just pinging a particular site. Just tested with ping -c 1000 to a US site.

Mot handsets are near impossible to find You don't need "exact" Mot handset to tie to the same base station. Most (all) DECT phones can be connected. I have my old phone to connect to the Mot base station. My older DECT is more than 5 years old so not expecting much but it works fine otherwise. Only thing is caller ID is not sent from Mot over and that is because a different phone make would operate with limited functionality.
