Dropping ADSL Connection / Connecting Back?
Mar 2, 2012
I have been having a weird connection issue for a week or so.The problem is at the first time i boot up my modem it simply cant connect.DSL Line LED keeps blinking- handshaking and training as it says in modem config page.After maybe 5 minutes or 2 hours, totally random.It picks up the connection, i can use it for hours until it randomly drops down once again.Ive contacted my ISP and they came over two times, they state the line quality is not suitable for my connection speed and it will be solved if i drop down my connection speed.Doing that is a painful process cause there is no other speed/quota package suitable for me, so i wanted to ask you people about it before i take action.
My modem is a Dynalink RTA1320 and i tried with another modem, tried mine in a friends house.Plus i went to the place where the cable enters my house and tried over there too, it didnt work as it should pick up in about 20 seconds.Here are stats my modem shows in the config page.[CODE]

We have an ADSL2+ line from a WIC in a 1841, everything has been fine for the last few years and then the last few months the connection going down. When checking the interfaces the ATM0/0/0 is up up and the same for the dialer interface we are using, they are both up/up, but this still needs a reload of the router to be functional again, shutting the interfaces does not bring the connection back up.
I am not an expert on ADSL lines, I have never really had a problem with anything previously. The router was running Netflow to a network monitor wondering if this or logging was causing an issue with entries in the buffer??
Here is an output of show dsl int, would change the firmware, it has been fine all this time before though we are running IOS 12.4(24)T1 advseck9-m, as far as I can seen from our ISP the config for ADSL is all correct. [Code]

Recently, i bought a LinkSys WAG120N ANNEX-A to replace my old speedstrem4200. Well everything was fine, but after 2 days of it installed, it started to drop my ADSL connection.
Sometimes, it remain connected for 4-5 hours, then drop, or sometimes, it drop every 30min-1hour.I tried upgrading the firmware to 1.00.16, but no luck, it still drop the connection.I have 3 computer plugged to the router via cable(wired) plus 1 netbook(wireless) and 1 ipod (wireless).Sometimes, when 1 computer is turned off, it seem to make the ADSL connection drop when the LAN light turn off. I noticed everytime it drop the ADSL connection, in the logs, i get this:
Mon, 2010-11-08 22:24:57 - Terminating on signal 15. Mon, 2010-11-08 22:24:57 - Enter: tdb_store. Mon, 2010-11-08 22:24:57 - tdb_store: calling tdb_update.

I tried changing the MTU settings in the router to 1492 (my ISP default) but didnt work.
Tried changing the MTU to 1492 on every computer and still got the same problem.For now im using the WAG120N in bridge mode, and still using my old speedstream4200 as ADSL modem.

I have a Netgear DG834G v3 ADSL router which I have had since early-2007.
When I work from home I connect to office networks on a Win7 machine via a Rackspace-provided VPN using Cisco System VPN Client 5. It works well, except for one issue that is costing me time every working day.
I get intermittently disconnected from the VPN, without any warning or apparent reason.
Since I bought the router 5-6 years ago I have had no need to update firmware, so other than ISP configuration I have had no need to change the router at all and I can say it's worked well for me.
What would be the reason for my VPN connection dropping? Is this an ISP issue (my ISP is Carphone Warehouse/TalkTalk) that I have to take up with them or is it more likely a hardware problem with my router or a VPN configuration issue?
My instincts are to not look into VPN config at the moment as I know a colleague who uses the same VPN through a different router and ISP can stay connected for hours, even overnight.

I have 2650XM router and 2620 Router Both routers have built in WIC T1 CSU/DSU cards
2620Router --
2620Router#sh int se0/0
Serial0/0 is down, line protocol is down
Hardware is PQUICC with Fractional T1 CSU/DSU
Description: DTE side
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
[code]....
My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.

I'm looking for instructions on how to setup and connect two RV082 routers together with a crossover cable between their WAN ports. This is to connect two separate LANS together via an ethernet connection. For staging we are setting everything up with a crossover cable in our shop. Ultimately the crossover cable will be replaced by a microwave link between the two LANS several miles apart. There will be no internet connection.

I searched a lot but couldnt find a clear document about connecting 2 G.SHDSL routers back to back.First of all I am not sure which type of cable (RJ11) is used for connecting two 878 routers. Does it have to be cross or straight cable.
Which RJ11 pairs will be connected each other [code]
According the configuration samples One router must be CPE and the other must be CO for simulating DSLAM.

I live in a Townhome complex so inSSIDer displays a lot of wireless activity. I have noticed that many of the routers channels are listed as 6 + 2, 4 + 1, etc., while show only a single channel. I have been able to "temporarily" replicate this by setting the Channel Width on my DIR-655, by setting channel width to auto, and when I am successful it displays a speed of 300, both in my task bar and in inSSIDer. However, that is usually short lived and the channel for my router reverts back to a single channel and the displayed speed drops to 130 or 144. My neighbor's Netgear is rock solid at displaying dual channels. Well, that and besting my signal strength. :-)
I have the router manually to channel 8 because none of the routers, judged by their displayed strength, use it.So, I guess my question is; how do I stop my DIR-655 from dropping back to using a single channel, which I interpret 20MHz, even though it is set on auto?

We installed one of these devices as our gateway a couple of weeks ago, flashed the firmware to 1.2.4(003) and it worked perfectly until this morning where it keeps resetting the ADSL every minute and losing the web interface to the unit.
The log endlessly reports this:
Feb 24 11:26:00 SRP547W cron.info cron[8779]: (root) CMD (/sbin/check_gn)
Feb 24 11:26:00 SRP547W cron.info cron[8781]: (root) CMD (/sbin/check_ps)

I have bought a WAG320 & ever since I've had it the ADSL line keeps dropping every few hours. The LAN network is fine & I have 7 computers connected to the router wirelessly. When I press the re-set button on the back of the router everything is fine for a few hours then it starts doing it again?

I have a ASA 5505 configured with three VLANs: Inside, Outside, and DMZ.I am running an exchange server on the Inside network and have configured NAT to allow connections to it from outside. This works fine. I can also happily connect to it using it's internal address from the inside. In the DMZ I have setup a linksys router to work as a guest wifi network. I configured the ASA to block any traffic from the DMZ to the internal network.This has been working fine for the last few weeks.Wireless users cannot access any internal resoureces, but can browse the internet etc.. etc..
My problem is that I want users to be able to connect to the wireless with smartphones, tablets etc..., if they do so, they can access the internet, but not get their email. From my (limited) understanding, the problem is that the ip address I am trying to connect to is the same ip that I am transmitting from. Is there any way to send the packets to the outside network and then loop them back to the exchange server?

A Layer 2 switch with IP Address 192.168.1.4 (Vlan0), subnet 255.255.255.0 is physically connected to ADSL Router with IP address 192.168.1.1 (which is also the gateway address for the switch). The problem I have is that all the devices connected to the switch can intercommunicate but are unable to communicate with devices connected to the Router. I guess this may be something to do with how the Vlan is configured on ADSL router?

My desktop however, does not have built-in wireless and therefore would have to connect to the ADSL router (Netgear) through ethernet but this cannot be done as the router must remain in my bedroom, much too far away for cables to reach.I bought a USB wireless connecter for the desktop but it doesn't seem to work. It connects but gives "Local Only" as the connection.

I have a problem connecting wifi router(airlive wt-2000r) to my ADSL modem(webstar epc2203ed2.0) using utp patch cable. When my PC is connected straight to the ADSL modem everything works like charm. But when I connect modem with wan port on the router and router with my PC I get no internet access. The network shows as unidentified network and win7 troubleshooter says: Default gateway not available. Connecting them two devices seems pretty simple and I dont think I am doing anything wrong so what could be the problem?

I have a Wimax internet connection via an ethernet cable from a small roof top receiver dish. Inside the house the cable (RJ45) is plugged into the POE slot on one side of a small electrically powered black box, and from the other side, an ethernet cable (RJ45), connects to my PC. I want to share my internet connection with my HTC mobile and would prefer to make use of an existing Belkin 54g ADSL2 modem/wireless router (Belkin F5D7633) if I can. As this router's incoming port is specifically for ADSL my internet RJ45 cable can not plug into it. I have been advised that I can still utilise the router part of the Belkin though, using my PC as an access point, by plugging the ethernet cable from the PC side of the little black box into LAN 1 on the router, then joining the PC to LAN 2 of the router with another ethernet cable.I did not alter the configuration of the Belkin at all (having reset factory defaults beforehand), mainly because although I could access the internet from my PC and my mobile, I could not access the IP address of the router, presumably because the properties of the local area connection on my PC remained unchanged with the IP address (172.168.1.149), Subnet Mask (255.255.255.0), Default Gateway (172.168.1.1) and 3 DNS addresses (172.168.1.1) (10.30.0.1) (8.8.8.8) as they were before hooking up the Belkin. The IP address the mobile received through WIFI on connecting to the Belkin was 172.168.1.148
I was not unduly concerned about not being able to access the configuration of the router as everything was working as I had hoped it would and even when I powered off my PC I still had internet access on my mobile. On rebooting the PC, however, I found that the router changed the DNS addresses on the PC to 2 only, both identical (192.168.2.1) and the IP on the mobile was allocated 192.168.2.2 Although I could still access the internet on my PC, I no longer had access from my mobile although the WIFI connection to the Belkin showed as being 'excellent'. When I did a 'repair' of my internet connection, hoping to revert to a fully operative state, the PC configuration changed again as follows: IP address becomes that of the router (192.168.2.1), Subnet Mask (255.255.255.0), Default Gateway (192.168.2.1), 2 DNS addresses (192.168.2.1) and the IP address allocated to my mobile remains (192.168.2.2) This configuration means I have no internet access from either PC or phone, but CAN access the router configuration. I restored a usable operating state by unplugging the power from the router, transposing the cables in the LAN ports on the router (swapped cable from LAN1 to LAN2 and vice versa), turned off WIFI on mobile and waited a minute or two. When I powered the router back up and switched on mobile WIFI again, everything was restored to the original working state and I have, once again, access to internet on both PC and mobile. It is very frustrating, however, to keep performing this ritual and I wonder if any of you more technically minded, know a way to work around this, perhaps by manually changing the configuration of PC or router?

I am trying to connect a wireless router (EDIMAX br-6228nc) with a ADSL router (NETGEAR). i assigned the LAN IP of the ADSL modem to 192.168.1.1, subnet mask 255.255.255.0, and enable DHCP server.then i connected a LAN port from ADSL router to the WAN port of the wireless router. i assigned IP of the WAN port of wireless router to 192.168.1.10, subnet mask to 255.255.255.0 and default gateway to 192.168.1.1 now on the LAN side of the wireless router i assigned IP 192.168.0.1 and subnet mask 255.255.255.0 enabling DHCP server.on the client pc i selected the setting of automatically assign IP setting (which it got 192.168.0.100, default gateway 192.168.0.1) but my client pc is not able to access the internet.

We currently have a main network running through a static broadband connecting using a Cisco 1700 ADSL router, everything is working fine locally.
We are looking to rent some space in an office nearby so im going to order another business adsl connection with static IP for this site and i currently have a spare 1800 router.My question is can the cisco routers connect up like a VPN connection so both sites work together and will the connection remain online constantly so from the remote office we can access all our servers from the main network?
Also how does the IP addressing work on 2 sites. The main network uses 10.120.21.x and DHCP is assigned from a cisco router. Does the remote network assign from the same DHCP server or would the remote sites cisco router need to be setup to give out DHCP to local machines. If so what would be the best IP setup to use.

securing a back-toback connection using E1.The connection is between two cities, using 2x CISCO 1841 router + VWIC-1MFT-E1 interface at each city.
The E1 connections has been provided by our local telco, and they are completely private. The customer is a bank, and they asking me if this is a secure connection or not. If possible, we need to guarantee that no body can get access to the bank network even if they brought E1 modem at one of the ends (telco PoP).
